T-Mobile HTC G2 "Unable to connect to network"

EDIT: Just got off the phone with T-Mobile Tech Support, they tell me theres nothing more beyond a Factory Reset that could help the issue, and seeing as I've already done a factory reset a few times to no avail, I should look into getting my money back for this device.
Okay, so I purchased an HTC G2 from ebay. I know this was my first error in judgement, but I have a limited budget so i took what i could get.
Anyways, I currently have T-mobile on my Unlocked Iphone 3GS, but I've grown tired of Jailbreak problems and using 2G data speed.. So i Found this phone on Ebay, and purchased. when I got it, I quickly popped in my already active SIM card and got NO SERVICE, looked around on the phone and found the Network Settings, went to 'Network Operators' and searched for a network. T-Mobile and AT&T shows, but does not connect to either. when I inserted another T-Mobile SIM card, the same error shows. ( thought maybe my SIM was too old to receive 4g or some BS like that.. lol)
anyways, I dont need to Unlock my phone, I dont plan on using it on any other provider or in any other country. All i want is for it to work with T-Mobile, in america. is there anything I can do? or should I just send it back to the Ebay seller.
any information needed, let me know and I can get for you.. its running:
Android 2.3.4.
Baseband: 12.62.60.27U_26.13.04.19_M
Kernel: 2.6.35.10-g96de068

Is try a factory reset. Re insert sim. If still doesn't work call t mobile support. If still no go file an eBay complaint and send back broken phone for a refund.

Okay, thanks I'll try that right now.
Also, do you think T-Mobile will offer support to me, although i did not purchase the phone directly from them? They got testy with me a while back when I was having issues with the Dash.

Okay, so I just tried both Soft and Hard factory reset and neither worked. re-inserted SIM and still get either "this SIM is unsupported" or "Unable to connect to this network"
I also get an Alert on the Drop-down menu that shows " the network (T-Mobile) is Unavailable.

How old is your SIM? The G2 uses a newer SIM; go ask for a new SIM at your local store

Thanked you instead of quoting! Oh well, this was useful advice actually.
He is right - I had to get a new sim card when I got my g2 in order for it to function as a phone!

Oh, see then I suppose I wasnt wrong in thinking that then. so, If I go to a T-mobile and just get a newer SIM card, all should be well?

My SIM is about a year old, I also tried my sisters SIM which is a bit newer and receives 4G on her LG Optimus, I can still try to get a new SIM though, my question is if its free or not?

yes its free just tell them the sim is malfunctioning

Thanks, but after talking with T-Mobile tech support, we've found that my sim is up-to-date enough to receive 4g, and if its working in another phone then thats not the issue. it appears that the phone itself is malfunctioning in some way that prevents it from receiving any network. I've contacted the Seller and she's agreed to a refund. this is a real disappointment but its the only option left for me.
Unless anyone knows how to fix the problem of the G2 not accepting any network. After some research I've found this to be a common problem after an attempted Unlock of the device that went wrong. but, I've found no clear solution to it. Just alot of people complaining about it. I didnt attempt any unlock of this device, nor did I buy an Unlocked device purposefully.
the sad part is, I've only had the phone for two days, with NO SERVICE and i still love the device. IF i could find a more trustworthy dealer, without spending close to $100 more than I already spent, I'd love to use it.

[Q] anybody else having problems with thier sim not working or picking up network

been using the the phone for a few days and suddenly stopped picking up signal or network connectivity. i have tried hard reset, rooting and even check my imei and its clean not blocked what do. halp.

I concur on going to T-Mobile and getting a new sim card for free.
In the least it sounds like your card works partially, so why not get a new fully functional one...

I had the EXACT same thing happen to me.
Call tmobile and have them send you a replacement phone--it was the only thing that worked.
(mine happened within a day of sim unlocking my phone...no clue if there was a connection).
tmobile WILL replace your phone, even if you bought it on craigslist. When the guy tells you 'no', tell them you would like to speak with someone about canceling your account.
Tell that person your story--how you are a good customer, how this phone was working, doesn't work now, etc...
Tell them that AT&T (true) will replace a phone you bought on craigslist, as long as it was an ATT phone and still under warranty.
This worked for me.
Worst case, you can send it back to samsung (but they won't send you a replacement...you have to send it in)
Good luck!

Simple Mobile & Samsung Galaxy S3

Hello Guys,
Strange problem here, I am a simple mobile customer, using a Samsung Galaxy S3 ( Unlocked , rooted and have custom rom ). The phone was working perfect until 8 am yesterday! I didnt do any changes , all of a sudden the phone will not register to the Simple network.
However, the sim works fine with an S2! AT&T sim works fine with my S3 also! So i can't figure out what the problem is !!!
Thanks,
Joe.

Simple mobile user here. Works fine for me. maybe restart phone? check the network setting, maybe it routed to different carrier.

Might be blacklisted? Try to do a complete wipe and reinstall the system.
Sent from my SGH-T999 using XDA Premium HD app

Sounds like it was blacklisted.
I was wondering if blacklists apply to MVNOs. Like the case in point, will a phone blocked on T-Mobile work on Simple Mobile even though Simple uses Tmobile network.

As of 31 October 2012, the U.S. Cellular Providers are sharing IMEI/ESN data to ensure that phones blacklisted on one carrier CANNOT be activated on another carrier. T-Mobile and AT&T are also tied into the international GSM IMEI Blacklist Database to ensure that phones blacklisted overseas cannot be activated in the U.S. and vice-versa.

Is there anyway to protect yourself while buying a used phone off of ebay/craigslist to make sure the phone is not reported stolen later?
Thanks

Meet them at a service store if using craigslist for a rep to check the status.

Sounds like the imei is blacklisted likely stolen phone. I always buy phones online and ask that they have the original box so I can avoid this.

The phone was bought new though! I have the box and everything and it did work on simple mobile for about month and a half! the phone is rooted and flashed multiple roms but no luck!

Go into settings and see if the imei still shows up? Sometimes the IMEI is lost while flashing roms. This would not allow the phone to get service. Was this after you flashed a rom?

I'm having the same problem! Except it stopped working around Friday which was December 14th. I've tried to troubleshoot this myself and the only thing I can come up with is that it's because I unlocked my phone. I got this phone brand new mid october and I've been using simple mobile with it since. Then last week I used that free unlock for Galaxy S3's and Note 2's via dialing the code in and going to the the network lock and switching it off. Last Tuesday, I tested it with an AT&T sim to confirm it was unlocked as I needed it for use in Japan and it worked fine. Then it suddenly stopped working last Friday.
Here are the things I've done:
1) Attempted to use a T-Mobile/AT&T SIM in my phone to confirm that my phone works and isn't "blacklisted" I've called and texted with those sims.
2) I put my simple mobile SIM into another T999 Galaxy S3 and it worked fine without setting up APN settings. I received my texts and voicemails as soon as the SIM was in. The only difference between my phone and that phone is that I unlocked mine and my friend left his locked It was the same model phone, the T999 T-Mobile version of the S3.
3) I've called up CS for Simple Mobile and they've went through all their "troubleshooting tools" and even called up their tech support with T-Mobile to confirm that my phone is getting coverage. The interesting thing that they kept telling me that is on their system and T-Mobile's systems, they see my phone as connected and idling which means I should be getting service.
4 and 5) I've factory reset my phone and bought a new sim card and did a sim swap and still no go.
And yes, if I type *#06#, I get my IMEI so I don't think my IMEI is "lost" unless there is another way to check. I've looked elsewhere for the solution and this is the only post where I found someone having the same exact problem as me.
The method I used for the unlock is this one: http://forum.xda-developers.com/showpost.php?p=34661189&postcount=1
Any help would be greatly appreciated! Thanks!

i got it same problem has no one fixed this or even no WY it happened . no help on the net anywhere

Phone probably blacklisted. Go to check esn free website. On the dropdown box look for the blacklisted imei and enter yours to see if it is in their system. You can also try calling T-Mobile.

Finally I brick my E973,, :(

Couple days ago my beloved Bell E973 wont reay sim card.
Here is what happed. the original from bell, but I bought a unlocked code to use my Rogers sim. It's working perfect for 2 or 3 weeks. I love the screen. personal I like it bettter than S3.
I did not root or unlock the bootloader and one day when I put sim card in, it just said NO SIM. I tried with bell sim. same
So I rooted and tried all kind of ROMs, even F180S. that's fun. but still wont read sim.
If anyone buy it as a parts or want to fix it. let me know. I am in Toronto

You tried to re-unlock it ?
Also, if you flashed korean firmware, your radio will mostly be gone.

no really to re unlocked it, since I tried my friends Bell sim. doesnt work

i saw your post on kijiji lmfao !! we live around each other lmao!!

Did you put it in the proper way?
I made the mistake of putting a sim in the wrong way once on my BB and even took it to a Rogers store and then felt like an idiot after the guy pointed out what I did.

It's still under manufacturer warranty
Sent from my LG-E973 using xda app-developers app

Two things about your phone:
I may be interested in it for parts, depending on price of course. Mine has a dead spot in the digitizer, and as I bought it second hand, LG won't warranty it for me. I'd not want to spend more than the price of a screen/digitizer assembly, so it might be worth more to someone else.
Have you tried a different sim in it? If the phone is unlocked, try a friend's sim card, maybe your sim just died. Edit: missed your reply about trying your friend's bell sim

Have you tried a hard reset?
Have you tried reinstalling the original rom, using the original KDZ file and the "unbrick" method?

Can you browse internet, play store, or use any program with data connection via wifi?
- first, it might be the unlock procedure did it. I had 2 out 5 devices ran into this scenario after doing a factory unlock.
- second, but unlikely and super scarce situations, Bell might have locked up your device's IMEI that caused it. I got one relative that the carrier locked up his phone after doing a factory unlock.

My Rogers E971 stopped recognizing SIM cards yesterday. It is unlocked/rooted. Hoping I can reroot/lock bootloader and send in for warranty service. Still trying to figure it all out.

same problem

I am hoping to set mine back to stock and send in for warranty servicing.

Optimus G sim card inserted or removed all the variations of the device automatically restarts.
Did you notice this situation?
Inhabitants of this problem, removing or inserting the sim card would not open the device?

Woo911, you have used wrong title for your thread thus eliminating people who might know a solution to your problem to ignore the thread, inability to read the sim doesn't mean your device is bricked.

When I first got the phone it would reboot when I inserted and removed SIM cards. It has since stopped doing this.

Just an update. I couldn't figure out how to unroot and relock my bootloader. I ended up sending it off to LG for warranty servicing via my carrier and they fixed it free of charge.

Calls and text not working on AT&T?

Hey guys so I woke up this morning and noticed that I can't make calls or send texts. I can't even run those codes through my dialer to check on my data. Which is weird since my data is working perfectly fine.
At first I thought it was my apn settings that got all wonky but I put my Sim in my Optimus G Pro which is complete stock and I get the same results. It's currently Sunday and the AT&T store is closed. Do you guy's think it's a problem on their end or would it possibly be my Sim card that might have gotten damaged? I almost never took my Sim card out, it's stayed in my g3 for most of its life. I haven't taken it out for maybe 5 months now and everything was working perfectly yesterday.
I would just like to hear your opinions on this please.
Edit: All working now, guess it was a tower issue.
