My [CDMA]Galaxy Nexus will not connect to 3G netowrk.

I Just took my phone back to stock, locked bootloader state and that still did not work.
No amount off turning data on/off works and neither does switching from CDMA/LTE to CDMA.
Is there a number like *228 that i can call to try reactivating it?
Is there anything I can do short of taking it back?
and my wifes incredible 2 can connect to the 3G.

Have you taken the SIM out and booted the phone up without it and then powered it back down and then put the SIM back and powered it backup to see if that does it?

nope, but i will.
EDIT: Nothing.
powered down, simcard out, power on, powered off, simcard in, powered on.
Simcard out I was actually NOT on any network at 0dbm. Simcard in it says i am on a network, with signal of 120dbm...
booo
I sure hope these **** third party retailers have one still.

It takes a minute to connect sometimes...give it time ..toggle wifi helps.

i have been battling it all day.
Not once has it connected to 3G.

Am I really the only person with this problem?
crap.

You aren't the only one...I had to return mine. I hope they get their head out of their anatomy & fix their radio/signal strength issue. When they get it fixed I will get another one, but I didn't want to risk my return window ending before they get it straight.

tomorrow is my 14th day, it will be returned tomorrow

This just started happening to me on my 20th day of having the phone...after over 2 hours sitting in the Verizon store yesterday they told me that a maintenance release was expected to be pushed out the end of January that "SHOULD" address this exact issue. Other than that they told me I was SOL.
So I am now carrying around a brick that is less than 30 days old. I am starting to wish I didn't trade in the Rezound I was borrowing until the nexus came out.

This happened to me 2 days ago. It is still not fixed.
I can connect to V's 4G, but when I toggle to CDMA, I get gray bars-no data connection.
I don't know if my 3G antennae got fried or what, but is there a way to reset it?
My Galaxy Nexus is rooted/unlocked but no ROMs.
I don't remember messing around with the radio.
I have tried rebooting, wifi-toggle, airplane mode toggle.
I have not tried flashing 4.0.2.
I have not tried removing the SIM card then turning it on.
I have not tried doing a factory reset.
Any suggestions?

I had this exact problem two days ago as well. I went to the Verizon store and the only thing they tried that worked was giving me a new SIM card. Try a new card. Why mine stopped working for 3G data I do not know.

I don't think it'll connect to any network if the sim card is out of the phone, its possible you have a bad sim card.

I do not have anything real helpful, but I can tell you that flashing 4.0.2, doing a factory reset, relocking the phone, or swapping out the SIM card does not help this situation.
Just out of curiosity...What method did you use to unlock your phone? I am just wondering if its a certain method of unlocking that is causing this issue. I am unaware of anyone having this problem that has not unlocked their phone.

I've got a GSM not CDMA version but I got 2 phones from different places. The first lasted 3 days before it stopped connecting to my network. It went back under warranty and was acknowledged there was a problem - awaiting return, it's being repaired now.
My second one had lasted around 3 weeks and is now doing the same thing. I'll be taking this one back as well.
My sim works perfectly fine in all my other phones (HTC's and iPhone's) so that can't be the problem.
First phone was unlocked and custom ROM loaded. Second one is as per factory, hasn't been touched so IMO it can't be related to any "customization".
IMO Samsung/Google should have waited another month and sorted these issues out before releasing the phone. I won't be buying another Samsung phone after this one

It just started happening to me a couple days ago. It was working fine. When I'm on wifi for a extended period and switch to 3G it won't connect. But I can connect to 4G. If I reboot the phone it will connect to 3G.

Now you've got me worried. I am hoping that VZW was going to issue a fix & then I would buy another Gnex. If it is gonna commit suicide 3 weeks later...

connection issues
I have had similar issue.
Powering phone off did not help. For whatever reason, pulling the battery reset my data connection.
Its happened twice as of today.

The same thing is happening to me. If im on wifi for a long time and try to go to 3g, i just get the 3g signal with gray bars and no data connection. The only way i can get it to work is by rebooting my phone. Im running bugless beast, which is a stock rom, but i dont think it has anything to do with it.

this just happened to me today. yesterday 3g was fine now nothing. and with lte constantly dropping this is just a glorified "stupid" phone. i contacted samsung support and they said i need to contact carrier. i reverted to stock and flashed stock recovery and locked phone and still no luck. rebooting and removing sim does nothing. we got screwed with an inferior product

I was experiencing these problems all day yesterday. No 3g, only 4g. Reverted to stock and tried everything listed in this thread with no success of gaining a 3g connection.
However, i looked at my phone this morning and i have 3g connectivity again. I'm going to assume there was some maintenance going on because it hasnt dropped since being awake

Sim Card Removed - Restart/Reboot Phone

Hi there
i own a galaxy S3 TMobile version for 2 months now.
I recently update on last rom and since then i am getting the following error.
Sim card removed. Replace the sim with a valid sim and restart/reboot the phone.
I am not really sure if i wrote the message exactly as it appears but thats the meaning of it.
I have unlocked the phone to use it on Greece.
I have the same sim on it, since the beggining.
I didnt had the problem before the update. And for sure the problem poped up some days after the update.
When i see that msg the most of the times (if not always) data is enabled.
I should also say that when i see that msg the phone is just sitting untouched. Phone has never dropped or anything like that.
For sure its annoying.
When i restart phone sim is working perfectly...... ..
Has anyone heared about it? Anyone who faces the same prolem and found a solution?
I tried to google it ut i came up with no answers...
Any help is welcome.
Thank you in advance

have u tried a different SIM yet?

I had the same kind of issue on my previous phone. However, there is no data on my phone that I had to reboot my phone a few times to establish data connection. Secondly, sometime I missed called. Replacing SIM card may not help either. A few people had reported the same kind of issue on T-Mobile Support site.

I tthought I was the only one plagued by this issue..
I have this same issue. It usually happens whenever I lose network coverage......it happens repeatedly.. This issue started happening after I updated to jelly bean...ICS had no problems..
I have changed my sim 3 times, installed several touch wiz custom ROMs, changed my base bands and kernel...The issue remains prevalent after all these..
The only way I have been able to resolve this issue is by switching to an AOSP ROM like cm10 or paranoid android rom
I hope a fix for this issue is found soon cos i am tired of restarting my phone everytime i lose network coverage
I have attached a screenshot showing this

replacement sim ractified the problem

I had the same problem the other day when I was driving home from work. I think it happened when I went from 4G to 2G coverage. And also, when I'm in 2G coverage, signal fades out completely and comes back on 10 secs or so later. I went to Tmobile and replaced my sim with a new one and I had no problem of such ever since. .. at least so far so good.

Believe me I have Odin end back to stock n the issue still persists.....changing sim cards is only a temporary solution....
The problem always comes back especially if you always in an area with no network signal

Warranty exchange! Samsung should replace it. Say won't read sim card. Or tmobile

It seems that it happens when the data signal is bad.
Yesterday i had to reboot more than 3 times inside in a 4h period.
Wth........

First & foremost,
How did you "unlock" your phone? Did you mess with the NV data??
Or were you a good boy & had T-Mobile do it for you?
It sort of sounds like T-Mobile may have disabled your SIM card altogether....which may happen if you screwed around with the NV data.
If it was properly unlocked by T-Mobile you should be able to stick whatever SIM card in there now. Easy to test, go down the street to your nearest Greek mobile telecom store & ask if you can test a prepaid SIM card in your phone. Assuming the GSM networks are to some degree similar to the US T-Mobile networks, you should even be completely in good shape using local GSM service.
*IF* you get the same issues with the local SIM card....well screw it then. Go protest in the streets about the austerity measures in effect at the moment. Or just be a lazy Greek bastard & demand 14 months salary paid, require retirement at age 50 and lastly *NEVER* pay property tax on anything.

Well i have unlock the phone through internet. I had no issues for the past 2 months at all and yes i am using a local sim card from the beginning. The problem came up with the last upgrade!
Besides that i have a backup of the nv data but i am pretty sure that isnt the problem.

Foking politicians and goverments who have been stealing money for so many years. That was the problem and not the people!
I wish i knew why you mention all these!

sim card removed
I'm having the same issue with my s3
I tried to unlock it using this method
http://forum.xda-developers.com/showthread.php?t=2014982
I'm not sure if it worked, but perhaps messing with NV data screwed something up??
I upgraded to jelly bean 4.1.1
I tried cleaning the contacts on the sim
I replaced the sim at WIND
I even tried a factory reset
Nothing worked so far.
Has anyone figured out why it's doing this? Is it hardware related? software related?

In the same boat as you...I thought i was the only one..
on wind's sgh-t999v Galaxy SIII ... unlocked it like you did, and I'm getting a no sim card, restart required error, get it about every 8 hours or so..
i ported my number over too, but it says under "my phone number" in settings.. has a completely different number than what I'm currently using.. not sure if that has any effect..
tried restoring to factory settings too.. nothing seems to work...
if anyone has any info that would be much appreciated...

From the cold boot and after the error message goes away, does your phone has data connection?
I got the same error message on my previous phone. However, it would not establish the data connection.
Watch this video to see if your phone behaves the same way --> http://www.youtube.com/watch?v=GRB-cPD-JlE

mine doesn't do that, I have a data connection almost instantly where I have a signal
the error goes away after a reboot, but the error stalks you, and you never know when it's going to strike..
sometimes when it's in my pocket waiting for a call, while i'm driving with a headset on, at night while i'm asleep
for me, it isn't consistent, but it eventually happens..
I intend on taking it to the repair center for wind next week once I get back home (with the family for the holidays)

I don't think this issue has anything to do with if the NV data was messed with because my husband and I have the same phone purchased the same day 6 months ago. We both get the same error message and it's does not always happen at the same time so I am not sure it has anything to do with the network either. When it happens to him, he tells me it's happening but it does not happen to me. I googled the error because it is annoying. I will guess now that this issue has to do with the Gallaxy s3 and the update to the firmware. I can't wait for a better update.

Hi again
Since I know that there are a lot of people facing the same problem I thought it would be nice to give the solution on this kind of problem.
It seems that when you update via kies (of course on stock roms) something goes wrong. Recently I install the latest rom using odin and except that I found so many new things that I couldn't see before I also had no sim problem again.
So I am pretty sure that this kind of problem appears due to the kies updates. And from what I saw there where more.
If anyone else try the same please let me us know if it worked.
Good luck to u 2.
Btw yes I had that problem when the data signal was almost 0... Maybe 0.... Only then!

First of all I want to ensure you that has nothing to do with the way I unlocked the phone.
Second nv data is untouched.
3rd the problem came on after an update.
As I said after a clear fresh install without ba kups etc, starting from 0 the phone works great again and also there are options settings etc that I couldn't see before. Crazy but real. If anyone else do the same thing and make a fresh install with the latest rom he will agree with that.
So... As you said we make good parties and have nice womens... But how you will caption those moments those special (girls) moments without a nice camera (phone) ?
Have a good day hehe.

For those on the SGH-t999v version of the phone... the reason you are getting this "no sim error" is because of the firmware update to 4.1.1. I've sent my phone in for repairs and the best answer they could give to me was that there's an issue with the current jellybean.. not sure about the SGH-t999 standard versions though...
Unfortunately, I've had to revert back to ice cream ....and guess I have to wait till Lime Pie (OS 5) comes out...
The issue is not the NV data as I have used that method to unlock my phone as well.

Thank you for your replies. I'm relieved to know that it is not the nvdata menu that caused this problem.
I sent my phone in twice now and I've recieved it back for the second time today.
The first time resulted in further Sim card error messages. I'm keeping my fingers crossed in hopes that it does not appear again.
If op would be so kind to lead me to the right direction as to how to use Odin, I'd greatly appreciate it.

Unlocked GSM Galaxy Nexus - No signal al all

Hello,
A bit about my Nexus: Bought it online, it's the Domoco version, unlocked, rooted and been using just fine with many custom ROMs.
So yesterday morning, I was talking on the phone with a friend without any problem. After hanging up for a few hours, when I was about to call someone else, I realized my phone didn't have any signal at all. And it has been like that until now, about 48 hours.
It happened so suddenly without any warning. The phone has never been dropped and everything else working just fine.
So here's what I have tried:
- Restart the phone (multiple times)
- Batter pull (multiple times)
- Factory reset the phone (multiple times)
- Wipe cache and dalvik cache in CWM (multiple times)
- Downloaded SetCPU and set the minimum to 700Mhz (instead of 350Mhz)
- Reflash the ROM and tried with other Custom ROMs (I tried Xenon, Xylon, PA, and Carbon ROMs)
- Reflash the Radio and tried with other Radios too (I tried UILH1, XXLH1, SC04DOMLE3 and some others ...)
- I also went to Tmobile and request a new sim card - same problem.
- I borrowed a sim card from another Tmobile customer to try it on my phone - no signal - but the sim card works just fine on his phone.
I ran out of thing to try and I dont understand what happened ... anyone has an idea or something else for me to try ?
Anyone experience this before ?

Welcome too my hell. I have a playstore one now but my first Gnex was an international one and it has this same issue. Its a PCB problem a warranty would fix. I'm near Chicago and a few people have told me there is an electrical engineer downtown that fixes stuff like this. I don't have a price but I think something like this is your only option. Mine sadly is still a battery charger:thumbdown:

I know it sounds stupid, but have you tried toggling airplane mode? I run into the occasional loss of signal when im at work [fair to weak signal in the big metal box], and a reboot is the only thing that fixes it for me. Mines a play store model.

Ah yes, I actually did try that too but forgot to mention. I tried toggle airplane mode on and off, also the 2G only mode on and off. But it didn't help with anything.

So I guess I have to look for an electrician then, cause I have this phone just a little bit over a year so warranty is a no go for me.
Thanks for the idea.
PS: anyone else has more option for me ? I just wondered if I have bricked my phone ... cause I flashed lots of diff. ROMs to try out but never gotten a bricked phone before, could this be a bricked phone ?

Bricked refers to a phone that does what a brick does: nothing. It doesn't boot, it does not light or attempt to boot, it does nothing. This is a signal issue..I have no prior experience with docomo, but this thread came up on search: http://forum.xda-developers.com/showthread.php?t=1574018, maybe it'd be helpful. Have you converted it to yakju or takju and tried a google factory image?
And this: http://forum.xda-developers.com/showthread.php?t=1554150. If it is a circuit board, it kinda looks like s.o.l., and im sad to say that to you.

I wanted to let you know that I experienced the same issue. I bought the unlocked Docomo Galaxy Nexus, and had it working fine on T-Mobile for half a year, and then suddenly had no signal on Tuesday. Nothing I did - factory reset, battery in and out, sim card in and out - could fix it. Have you tried using different sim cards in your phone to see what works and what doesn't?
I figured out that my phone will accept AT&T, and actually does connect to T-Mobile while roaming (I used an international sim card). But, my phone will say "Cannot find mobile network" when any T-Mobile sim card is inserted.

I also have the same problem with the docomo phone. ATT Sim card works. Tried other's T-mobile sim cards and it doesn't work. I wonder if somehow the IMEI has been blocked by T-mobile.

I know others who bought their GNEX through the Play Store and those work just fine with T-mobile. I tried their sim cards in my phone and it doesn't work. I don't think T-mobile is intentionally blocking the docomo phones, because I'm getting T-mobile through roaming, when I use an international sim. My guess is they're doing something to the cell network that just somehow leaves our configuration out. Hopefully it's temporary, but who knows.
Worse case, I'll just purchase a Nexus 4, because I love 4G data for just $30/month with T-mobile. Anyone else got suggestions?

Alright, update on this and there' good news. I called Tmobile and they said my IMEI is actually Blocked. The reason, according to him, is that Tmobile usually sweep the network to clean up all "un-supported" devices, so my device is apparently one of them and therefore got blocked about 2 days ago.
So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.

I'd love to know if you are able to get this unblocked and working as I have the same problem as of Tuesday. I was traveling and went into a TMO store, and they told me it was NOT IMEI blocked. In fact they looked at the IMEI and read the page and said 'it was not eligible for blocking'.

I called TMO to see if my phone is IMEI blocked, and through three levels of support the universal answer was no. I'm now fully confused because if it's a hardware issue, why did several people all have the same problem all on Tuesday. For those others who are having issues, can you see the TMO network but not connect to it? That's what I have, I can see TMO and AT&T but haven't been able to connect to either one since Tuesday.

So he said for this, he needs to escalate it to business support and they surely can unblock it for me, but I have to wait until Monday since they don't work on weekend. But well, that's surely a good news. phewwwwwwwwwwwwww !!!
So to all of you guys who are in the same situation, make sure you call Tmobile first before flashing crazy like I did LOL.
Thanks for all the help.

I'll call up T-Mobile tomorrow and ask if they IMEI blocked my device. I had them reset my signal and give me a new SIM card, but didn't realize it could have been IMEI blocked. I'll give them a call on Monday and let you know what the result is. Maybe it won't be too late to cancel my order on that Nexus 4...

I'm quite confused. I've been told last Thursday in a TMO store and with tech support that I didn't have an IMEI block, and the same with three reps tonight. I know the Sim Card is good, and so I'm being told its a hardware issue. However, several of the same phones had the same issue on the same day, so I can't buy it's a hardware issue. Has anyone with this issue flashed a new or different radio into the phone, either before or after the service loss? I have not, running it as it came out of the box.

I just got off the phone with T-Mobile Support, and they told me the device is not blocked. The reason is that T-Mobile cannot block or unblock devices that are not registered to T-Mobile. So I'm back to square one on this.

chowabbajack - When did you first have a problem, last Tuesday? Did you prior to that do any flashing or radio changes to the phone?
We're in the same spot....

I did not do any kind of flashing or radio changes prior to Tuesday, when I lost signal.

That makes me think its something to do with the radio software, because I am the same the problem overall doesn't seem as large as the number of phones I perceive were bought on the Docomo deal.

Ive been using the docomo version of the nexus as well on tmobile for almost a year and it was since last tuesday when it no longer recieved any singal. with some digging around and too many phone calls, I found that the imei number on the phone is not the same as the one under the battery. i have the generic 004999010640000 imei right now and it not sure how i got it. as i bought it unlocked.
what i have tried:
reboot, battery plug, reinsert sim, factory reset, root and flash, got a new sim card, relocked, unlocked
sim card works on other phones.
also i have called tmobile and samsung endlessly and this is what i got:
tmobile cannot unblock the imei since it is not from them.
samsung is redirecting me to their japan branch.
docomo i cannot reach.
my phone before last tuesday:
unrooted stock 4.2.1
been testing different things to see if there is any way to restore the imei
also using root explorer, i cannot find my efs folder....

I've got the same problem since last Tuesday with my GNex and T-Mobile.
Mine is not from docomo though, but the French phone provider SFR, unlocked through FDocomo apk.
Rooted phone, running 4.2.1., no changes whatsoever in the past month and it worked fine until Tuesday, so I don't think I'm responsible for having no signal.
Honestly, I am relieved to see we are quite a few to have this problem, and also very pissed at T-Mobile for causing all this. What should be the next step then? Is there any chances they fix the issue quickly? If not, I might just go to the competition. I've tried AT&T sim cards and they work fine.

I have the exact same generic IMEI number as you, which does not match the number under the battery. I'm not liking the news that you did flash and still no go. I'm a novice at this stuff so please keep us posted.

ESN Corruption on Galaxy Nexus GSM?

Just wondering if anyone with a GSM Galaxy Nexus ever had a their ESN get corrupted before. I had this phone for about a year, and decided to give it to a friend of mine for his birthday after from upgrading to the Nexus 4, and it was working fine for two weeks then a few days ago it just stopped working. It had this weird phantom airplane mode and all the settings was somehow wiped. This was on 100 percent stock. Only thing different was I had it on Straight Talk with the at&nt sim card and he ordered the tmobile versino because ST doesn't sell the att ones anymore. It worked fine till that problem happened. That was the first issue I had ever with that phone. I tried everything from wiping the cache partitions, and restoring the stock firmware and no change. Still had that airplane mode issue. So, I called customer support and thankfully I still had a month left of the warrenty thank god, so I talked to the tech support and what they told me to try didn't do anything. so, they told me to send it in. I guess the Original Problem: was the ANDROID - DATA SETTINGS CONFIGURATION - BASIC CONFIGURATION ISSUE, and they found:ESN CORRUPTED - WILL NOT CHARGE. This is from the email letter I got back with the tracking. Just wondering if anybody has had this issue before with a GSM version and what causes it. Im interested to find out. I tried looking and searching and found nothing for the GSM ESN, My friend is getting his replacement in today on his birthday, 6/6/13. Sorry for the long post. Just curious on what causes this issue. Thanks!

I don't think GSM devices have an ESN, that's only CDMA?

seems like its the same as IMEI being reset ?

My Nexus S did the same thing. Samsung refused to fix it under warranty. I was one of a few who had that problem in the NS community and there was never a solution found. If you do figure it out let me know. I flashed a rom one time that fixed it. I did a back up and when it rebooted it was gone and occasionally the IMEI would reappear.

[Q] Help with unlock

To state clearly at first. The new phone in question was not rooted when I purchased it, but I did root it. So the phone is rooted but not unlocked. I thought I should also add that I'm in Atlantic Canada.
As usual, I always seem to have an issue that I look and can never seem to find the answer. This leaves me asking a question that I'm hoping there isn't already an answer to because I know people hate that.
So here goes. I have 2 SGH-989D phones. One I got new 18 months to 24 months ago with my re-negotiated Telus contract. I got the second one "barely used" a couple of months ago and I'm pretty sure it was a Bell pay as you go phone as this is what the person told me. He said all of the phones they get are always Bell. He would have no reason to not be truthful especially since I had a Telus and he knew I would need to unlock it I purchased it because my existing phone was acting up and also the screen was pretty severely cracked.
What I found odd is that when I put the Telus SIM card in the phone, I didn't get any message that the phone was locked. I was immediately able to dial a number and the call went through. I could also send and receive txt's. The phone also says Telus at the bottom of the screen. What is problematic however is that 4g won't work. When go into the new phone under network mode info this appears "GSM/WCDMA(Auto Mode)" But when I look at my original phones network mode I get "GSM/HSPA(Auto Mode)" So, I'm thinking this is probably quite obviously the reason that 4g isn't working and I have no data available unless I connect to wifi. This won't do.
So, where do I go from here? I'm thinking i need to unlock the phone in order to do something about this probably? Or is there something else I can do to pick up the HSPA instead of WCDMA? I'm so irritated by this. It feels like it should be a simple fix since both of these phones are SGH-989d's but maybe it's not. Lastly, and I don't think this makes much of a difference. My old phone is 4.0.3 version and my newer one is 4.1.2.
Thanks and I'm hoping someone knows what or if I can do anything or if I should just give up. I really hate giving up so I'm hoping it's not the latter of the two options.

Moved to Q and A, and, please do not bump within the same 24 hour period.

The phone is unlocked or you wouldn't of been able to make calls etc with your sim.
My guess as to the problem is that your Bell phone is not a SGH-T989D, it's actually a SGH-i757M or GT-I9100M, they are called Samsung Galaxy S2's but there are a few models of the S2 out there. To verify your model either go to Settings > About phone and check Model number, or pull battery and look under it for the model number. To my knowledge, Bell has never sold the SGH-T989D model of the S2.

Thanks for your reply Almite. Unfortunately the phone is the SGH-T989D.. I know it's a weird problem I've got here.
I used to play around with satellites back in the day. One of the things we used to do with the boxes was to jtag the box, erase the memory from the primary chip and then flash it with a different STB's info. This would enable us to do some wonderful things.
Rooting and then unlocking seems like a similar process however I just don't want to flash the phone with something that is going to brick it. I guess I'm going to need to do something. This phone is no good to me this way. If I brick it, I brick it. What I would like from someone in the community would be to direct me to the easiest process to flash my phone with a telus ROM.
I have read A LOT and there are many opinions out there, but I'm thinking that there is probably a consensus on what is the best and easiest way.

Update
I have successfully installed Jedi Mind Trick using TWRP as it appeared to be the best stable one out there. Used Darksides superwipe and then installed JMT. Still have issue of GSM/HSPA on original phone vs GSM/WCMDA on the phone that now has JMT installed on. I must say, I'm pretty impressed with how easily it installed and the ROM itself however sadly it did not help my conundrum.
I'm thinking that there is probably a developer here up for a challenge that could probably assist me with my problem. I really would like to be able to pick up 4g on this phone, or It's pretty much useless to me. What I need to figure out is how I can change this phone to recognize the HSPA network instead of the WCMDA network as GSM does not appear to be relative to data. Not with Telus anyway it would seem.
Maybe this isn't even possible because it's hard coded into the phone or something. Anyone have any ideas?

Last update unless anyone has any ideas

Spent almost an hour on phone with Telus tech support. he explained that WCMDA should work fine as that and HSPA are essentially the same thing. Went through several settings changes and edits with him. In the end, he was stumped. The changes we made should have worked but did not. Therefore I supposed I have no choice but to give up. Guess I'll give the phone to my daughter as i don't want her to go online without wifi anyway.

Same issue
My wife recently cracked the screen on her Rugby Pro so I picked up a slightly used Koodo T989D and plugged in the SIM card. I had the same thing happen. Phone booted, made calls, all seemed well. The next day she realized she had no data connection. I rooted the phone, flashed Telus radio, tried different ROMs, even purchased the unlock code for it hoping for a fix. I can't seem to find anything that will allow this phone data connection of any type other than Wi-Fi. I would really appreciate any ideas or information that anyone has on this topic as I'm running out of ideas and buying another replacement isn't an option.

So I hunted and finally answered this question we both had. Go to Settings:Wireless and Networks:Mobile Networks:Access Point Names.
Since my phone was a Koodo phone it lists Koodo SP. Click the menu button then New APN. Name it whatever you want. I called it Telus. APN is sp.telus.com. Scroll down to MMSC and type http: // aliasredirect. net/proxy/mmsc (without the spaces. They won't let me post a 'link'). Under MMSC proxy type 74.49.0.18. MMS port is 80. MCC is 302. MNC is 220. APN type should be Internet + mms. Click the menu button and save. Click the circle behind your newly created APN and wait. In under 30 seconds I had 4G connection.
Hope this helps you.
