Q: No Data if Not Activated?

Hello. I am wondering if someone here might be able to clear something up for me. I bought a new EVO 4G off eBay a few days ago. I called Sprint to verify the ESN is clean.
The thing is, I don't have any intention to activate this phone, rather I bought it as a toy, and because upon coming back to the US for a vacation a few weeks ago, I finally saw what it looks like in person and I had to have it (Yes, I like smartphones). Of course ironically it FINALLY released in Japan just days after I left but that's besides the point.
Anyway, I have the WiFi turned on and the phone has found my location for the HTC Sense weather widget, however the internet won't load and when I try to connect to Google to use the Marketplace and such, it says there is an error communicating with the servers, and that my phone might not be set up for data provision.
Someone please tell me that Sprint hasn't locked down this such that you can't even use the Wi-Fi until it's activated. Though I suspect that is indeed the case...
...and IF that is so, then am I correct in the understanding that flashing it with some custom ROM would solve the problem? I have never rooted a phone before, though I do own a number of unlocked ones (Nexus S, Xperia Play, etc) and so I had intended to try it out with this, since I can never actually use this as a phone. But perhaps it might be more of a necessity than I had expected.

Not sure if this will help you, but if you flash Warm Z, or any other of the froyo/sense 2.2 ROMs, during setup it will ask you if you want to use it on the data network or only on wifi.
Since you don't need 4g anyway, I would recommend checking it out. One of my favorite ROMs.

I can't say this with confidence, because my Evo hasn't been deactivated before, but as far as I understood it, you should be able to connec to WiFi, whether the phone is activated or not. You shouldn't need to be activated to use WiFi. When you connected to the WiFi network, did it connect successfully and show good signal strength?

How about formatting the phone and then turning on airplane mode and then wifi. It should work fine
A drop of Chuck Norris's semen was placed on Android OS. We now have CyanogenMod.

Yes, being a used phone, I would highly recommend do a factory reset on it first. That way it will be clear of anything the previous owner might have done to it.
And yes, the phone will work on wifi only without a data plan, just make sure the phone is in airplane mode all the time, then turn the wifi on.

I had that happen to me with a old android when I did a factory rest you should have wifi but you can't use the market or gmail without a data plan from sprint at least I could not but I had a Samsung moment and it was rooted with a costume ROM on it I've never had my evo turned of so IDK..... If thats the case you can use other ways to get apps like Amazon or applanet thats what I did anyway......

Thanks to everyone who provided assistance. A few things:
1. The phone was actually still sealed. The security stickers were still on the phone and the manual, and even the battery was still unopened. Furthermore the phone itself still had the plastic sheet over the screen in perfect condition (something I've not even got from so-called new unlocked phones) so unless the seller went through really great loops to make it look new, it is apparently new. Though I will format the memory just incase.
2. I turned on Airplane mode as everyone suggested, and then when I turned on WiFi it let me connect to the Android Marketplace actually.
Actually, can I ask one more question, though unrelated. I want someone to confirm this:
I have two different contract carriers with me here roaming (Docomo and Softbank), both on Android Phones (the Xperia Play unlocked and Desire HD locked respectively). I have the mobile data transmission set to off (no roaming), however the actual phone service is on roaming. Every time I turn on the phones I receive messages from the carriers about roaming charges for data. I want to confirm that if the data roaming is OFF, and it is on Wi-Fi always, there are no charges for anything other than if I were to make a phone call, is this correct? I am 99.999% sure this is true, but part of me is really worried about returning and seeing a $10,000 bill.

but you can't use the market or gmail without a data plan from sprint

Yes you absolutely can. To the phone, a wifi connection is the same as a 3g connection, its just a way to access the internet.

You could still get charged for any texts/picture mail you receive, as those still go through the regular phone radio, not the data radio.

Drat...I've received a number of those actually, but all from the carriers themselves which I think might be free of charge.
Japan basically doesn't do SMS/MMS thus it's really not an issue. And while Softbank does to an extent, I can't seem to actually receive any while here, as it actually keeps saying I have undelivered mail.
But I am happy everyone here mentioned the Airplane Mode detail as I had no idea you could use Wi-Fi in it. I had been angry because there seemed like no way to shut off the cellular radio and that provided a solution.
Sorry if I seem paranoid, but I literally received a bill for $5400 last December due to a carrier mistake (and they actually had the nerve to accuse me of using an overseas phone when I CLEARLY was using a locked one) and ever since I have been scared about getting another. Currently Docomo is the only carrier in Japan that will allow unlocked phones to be used, though in doing so you are thus accepting that your data transmission charge will be capped at $120 a month instead of the normal $75 for its sanctioned (locked) products. But Japan is so far behind with smartphones I can't stand to use any of them.

[Q] Can't get international data roaming to work

I just got my G3 and left the country. Voice and SMS work fine, but I can't get a data connetion while out of the country. It didn't work in either the UK or India.
I'm guessing there's some sort of APN issue and I have a call into TMO tech support. The original call was to do #RON#, but that didn't help.
When I swap my SIM to my trusty Nexus 5, data works, so it's something device specific.
I've read about needing to force IPv4 when roaming and I tried creating a new APN with only that changed. One thing I noticed that's different between my N5 and G3 is there is no APN setting for Roaming Protocol.
Any ideas?
Thanks!

did you enable roaming in the settings?

Yes. One interesting thing is that the data roaming setting seems to reset on every reboot.

I have the exact same problem. Lg g3 t mobile, been to Germany twice in last two weeks and no data. All settings on phone are correct. After many phone calls with tech support, found someone who said they seem to have growing pains with new devices and the more they get feedback and realize there is a phone specific problem they can go to lg . Very frustrating but hopefully gets ironed out soon. I also came from a nexus 5.

That's not too encouraging. I was hoping that I'd have data sometime on this trip so I can actually use my new phone! Since it's new and still in my return window, I'd like a solution before I go home to decide if I should return the phone. I travel internationally a lot and it's one of the reasons I shifted to T-mobile from AT&T.
Tech support has told me they will have some sort of reply within 72 hours so hopefully I'll head something by end of day Wednesday.

I agree totally !!! Unfortunately we are early adopters of this phone. Tech support told me flat out that it will not be fixed for me while on my trip. I travel internationally for work and not being able to use data for google navigation and train schedule apps has been very upsetting. I will post something here as soon as they get back to me as well.

I've been trying to troubleshoot the tethering and found some interesting things. Looks like in an effort to avoid people enabling tethering without using the pcweb apn, they have broken the international roaming.
I think the problem is that you cannot use an ipv4 only APN. I added a new APN which was an exact copy of the built in one (which you cannot edit) and if I change it to ipv4 only, I get no data (in the US). Data only works when setting it to ipv6 or ipv4/ipv6. I haven't tried to debug this, but I think this could be the problem since when roaming internationally I doubt ipv6 is supported.
I also travel often to Mexico, so this is a big drawback.

Same issue in Canada
I just spent about an hour on the phone with Tech Support. Very friendly, but alas, I have the same issue. A ticket was entered, and she said she would get back to me today. If the LG G3 can't go International, my local T-Mobile store is about to get my returned handset. I'll try something else, I suppose. Glad I found this out within the first week of having it, what with the 10 day return policy.
Of note, the tech support person mentioned to me that I had to create an IPv4 APN (otherwise identical to the existing fast.t-mobile.com APN, which is IPv6).
I also tried selecting IPv4/IPv6, but that didn't work either. Neither GSM nor WCDMA works.
My co-worker here is happily connected on his Samsung Note 3. Frustrating to have a newer phone with a better processor, just to have my boasting neutralized by no roaming. :crying:
If I get a resolution, other than returning home or getting a new phone, I'll post it.

I really hope this isn't the case. I'm deployed overseas right now and get service just fine on my N5. If I can't get data with my G3 when it gets here in a few days, I'm going to be pissed.

Thanks for all the ideas. It's nice to know that I'm not alone in this.
I still haven't heard back from T-mobile and it's at 72 hourse since I reported the issue. I'm on another flight tomorrow to the UK, so if I don't hear anything by the time I land, I'm going to give them another call.
If they can't get this to work or at least give me a timeline for resolution, I think I'm returning the phone and will wait for the N6 (if one exists). Hopefully I can get them to waive the $50 restocking on return since I'm returning it for not working reasons.

This is a pretty big bug, I can't believe no one tested this before launching the phone. I sold my N5 a day after I got the G3, so if I were to need my roaming while abroad I would be SOL too. Not sure if I want to return it yet, once we get a custom ROM I'm sure we'll be able to get around this.

If it were me, I'd trade out to a different phone before I left for the UK. Still within the 10 day return period, so there's no penalty, and so you have data abroad.

I'm already in India, so it's not another trip. I'm home on Sunday evening, and Monday will still be within 10 day. I didn't really need a new phone, but what sold me on the G3 was the 3Gb of RAM and bigger battery. My N5 is sluggish and the battery doesn't last all day with all the software I have installed.

I wanted to post an update. I hadn't heard anything from TMO so I called them back to check on what's going on. I'm now in the UK and still have the problem (again). They really gave me the runaround this time saying that they needed to file a new ticket since my original ticket was filed for problems in India. They also told me that enginnering had responded that there were no roaming partners in India, which is just false. I kept mentioning that other people are having this issue in other countries and mt Nexus 5 worked just fine.
At the end of the call, they did file a new ticket and escalated to some other support team to resolve. I'm really not hopeful anything will happen before I return to the US. I told them I'm flying home on Sunday and that if I didn't have resolution, I would be returning the phone upon return.
If something happens in the next day (the timeframe I was told I would get a response), I'll post another update.

That won't work for this issue. I have a TMO US SIM and my free international roaming isn't working. The phone is locked, so I can't get another SIM.

To all having this problem - I am having a similar, but different issue. I just purchased a brand new T-Mo USA G3 yesterday. I run it on a T-Mo MVNO (Roam Mobility) since I don't live in the US. Voice works fine, I can see I'm on the "Roam" LTE network (which is really just a T-Mo USA LTE network), but no data. Proper APN is inserted and the SIM gets LTE data in the same location on my Moto X.
In the meantime I unlocked the G3 fully, no change.
Finally tried changing the network to WCDMA / GSM only and...I have data.
No idea why T-Mobile is blocking LTE when not on T-Mo itself. Will try in Canada tomorrow but expecting same results as everyone else, but will be interesting to see if it runs on HSPA+.

I tried disabling LTE and creating a new APN with IPv4 and after about 15 minutes powered on, still no data. Then I tried WCDMA only and still no go.

Latest update:
Just got off the phone with support again. The engineering team came back saying this was a handset problem and there are no known issues. I just did a full reset under direction of the support guy and still nothing.
I'll be returning the phone next week when I return to the states.
The support guy also said he will be posting on the TMO message board for other people to post issues with roaming. When that comes up, please post so they understand this is a wide-spread issue.
Maybe I'll rebuy the phone after I know the issue is resolved or by then there might be something better...

Quick update - just arrived back in Canada, and pleasant surprise - full LTE data on Fido! Just had to manually add the APN.

Can't Access T-Mobile Network

Woke up this morning and have not been able to access the T-Mobile network. No changes have been made that should have impacted the ability to connect. Greatly apprecaite any help.

If you made no changes then it's either your phone or the TMO system.
Sent from my LG-D851 using Tapatalk

Well first, obviously, did you try rebooting your phone? Push into Airplane Mode and back?
Second, how is it not connecting to the T-Mobile network? No data connections? Or voice calls? Not connecting to the network at all?
Did you check your APN?
Can't really offer help if there is no accurate description of the problem at hand.
And finally, if you can gain access to post on XDA, why not contact T-Mobile themselves? As I'm pretty sure they can help you far better than many of us here with this issue of network connectivity. :silly:
Just sayin'.

I have the same issue. After a few days of getting brand new phone the data connection is messed up
Thinking of returning and getting S5

Call up 611 on the phone (if possible) and say "Clear Location", that automatically clears out your phone connections and details (not your personal data) and resets the connections with the towers/antennas. You might need to speak with a rep or tech support to get that request, but they always do it if asked.
If you can't use the phone in question, call from another phone using 1-877-453-1304 and just give them your T-Mobile phone number in question and request the same.
Clear Location updates where your phone is being used and has it renegotiate its protocols, handshakes and talk, it essentially has your phone act like when it first booted up out of the box and was activated with T-Mobile.
I don't understand how the T-Mobile store didn't just perform that request/task with you when you were there....

They did do that and it worked in the store. But problem resumed when i got home

I would try the Clear Location again, just to see if it would fix it, if it doesn't, I would ask for a device swap in store to see if it works and holds.
It might be your account provisioning, but it was working fine then didn't, so it's most likely on T-Mobile's side. You can wait it out and when and if it works again, call up and request a credit to your account for the loss of service.
It seems to be your data isn't working at all but voice is, so you can check your Mobile settings and see if the APN is set to fast.t-mobile.com with IPv6.

Im going back today and swap for new phone. Im not sure if it was always working. Sometimes it works and sometimes it doesn't
When i first got the phone i went straight home and used wifi. I only noticed it 3 days later when i was outside. It was after that, that I started monitoring the problem
I get the 4G icons but little data coming thru

Yeah, I would try a device swap and see if that corrects the issue, since it seems the data reset isn't.
BTW, the 4G icon is for 3G+ (HSPA), which is slower than the actual LTE speeds. If you get LTE speeds, the phone will display "4G LTE."

I just swapped the phone and new phone works as it should. In the store the TMo employee had a G3 and we compared Ookla Speedtest. Mine was definitely not working like his.
I hope this new phone won't have a problem. They only waive restocking once. I was ginna swap for S5 but decided to stick w G3 for the screen

That's good to hear that you finally got it to work fine.
Also, in regards to the restocking fee, it is waived if the device is defective. They should not be charging it when the device is broken, defective or not working as it should. The restocking fee is for those who just don't like their device and want to swap out for another one.
You might have to fight with them about it a bit, but no restocking fees on defective devices.

LG G4 WIFI Stuck Trying to Turn On

This is my second LG G4. The first device had an issue where it would not boot up completely and when it did it was not reading the LTE sim card. My wireless carrier swapped it out. This device was working fine the first day I got it but I noticed that downloads were slow, like updates through Google Play. After investigating I found that even though the device was connected to WIFI, it was downloading stuff over the mobile network. Then, I started having problems. If I restarted the device, the Wifi button that you use to turn on or off wifi would become stuck and continually blink as it was being clicked but wifi never would come on.
I have tried resets to factory state. In some instances, this would fix the issue, but only temporarily. The issue would soon begin to happen again. There was even one reset where the device going through the setup process could not turn on wifi.
I think this may be a hardware issue but dread going up to the carrier store. I am past my 14 day period. They had to order me a new phone from the warehouse because they did not have any reconditioned devices but I don't really understand how it is okay for them to give out reconditioned devices for something that should be covered under the manufacturers warranty. I also don't understand why they cannot swap it out with the stores stock. When they ordered the last one, they told me 3-5 business days. This was on a Monday. Apparently something happened and the device never got ordered so Thursday when I called to check on the status of the device, I was told they had to do the order again. I was without a device on their service for eight days which in my opinion is also ridiculous.
I just really dread going up there and dropping my phone off for one of them to say we did a hard reset to fix it, and then I bring it right back home and it happens again and I have to go back up there. Something tells me LG didn't do a lot of QC when they were manufacturing these devices.
I wanted to know if anyone else had the wifi issue I have described above?

Just started happening to me today..wifi icon in status bar blinks like a stop light on crack and it won't turn on or connect to any wifi. gonna go to a sprint store to try to exchange it I'll let you know what happens

I hope you have no issues exchanging it. I got the same guy that supposedly originally ordered the replacement device the first time. Normally they make you come back an hour later but he rushed right out and said, "Your device is defective." and gave me the same spiel about how it is two new and they don't have any reconditioned devices so a new one would arrive from the warehouse in 3-5 business days.
The only reason I am still using Sprint is because they can get signals in places like hospital emergency rooms that the other providers can't because of the 800mhz. I seem to recall, but maybe my imagination is inventing something, that when I had issues with devices on "T" and Verizon that they swapped the devices out of existing store inventory, but I could be wrong.
At first I thought the issue was software related. Also, This will be the third time I have to buy a glass screen protector. The first one I got from Amazon. They never offered to replace it, although they should replace it. The second one, I got when they replaced my device. Today the dude tells me he can transfer my glass. Never heard of that happening without issues.

So sprint will exchange it cause I've only had the phone for5 days but i have to go to a different store to exchange it cause my store doesn't have any left with black leather..so back to the g2 running cloudy3.3 till i can go to a different store

4g connection issues with note 10+ 5g

This is going to be long but I want to make sure I give as much details as possible. I went to preorder a note 10+ 5g. Was going to do a trade in but right before I finished the order decided to go with the BOGO deal instead and add a friend to my account. I received both of the phones and had 4g issues. Most apps had trouble loading anything. If I waited with the app open eventually it would start loading things up but not all apps acted like this. They may hang some but worked ok. Speed tests showed I had a good signal. After talking with tech support on the phone and going to Verizon stores several times they still couldn't get things to act right. They switched sim and phone out in store. One of the store managers said my first order was pending and that 1 if not both of the phones I had were supposed to be in there warehouse and that I wasn't even supposed to have them. They told me the best thing to do was to return the phones and start over. They had trouble returning the phones since I wasn't even supposed to have them. What they had to do was to charge me the full amount of both phones to my account and the credit me the amount. They said after my billing cycle was over they would do it and once my account was back to normal then try to upgrade again (still ended up paying extra on my bill for that ). So I went into Verizon yesterday and did my upgrade and still had the same issue and if I wanted to return them again I'd have to pay the $50 restocking fee . So I called them AGAIN! They have a ticket out but I tried to see what I could figure out on my own. I downloaded a network switcher app and went to 3g and everything was slow but worked fine. Everything also works fine on wifi. One thing I noticed in the app when I ran a ping was that IPv4 connected but IPv6 failed. It said IPv6: fail (1). Anyone else having this issue or know what's going on or know a fix? This is very annoying!

A couple years back we had problems with my daughter not being able to send or receive text messages and after endless efforts on the phone and going to the phone store where they suggest a new phone we looked on her Verizon account and she had some restrictions on there somehow for sending text messages. Long story short look at your account with Verizon and look at every single little nitty-gritty detailed setting - there might be something on your phone line or both phone lines that disallow 4g? Have the store try a different SIM card - NOT ON YOUR ACCOUNT, BUT A DIFFERENT ACCOUNY - and if the 4G works fine on the phone with a different sim card with a different phone number and account then the problem is with the carrier account you have...

I went through everything and didn't see nothing. As soon as I returned the phones and went back to my note 8 without making changes to my account everything worked like it was supposed to again.

RE: 4G Connection Issues with Note 10+ 5G
Hello,
I had the same phone with the same issue and am on the phone with Verizon Wireless now. We found that the 5G version will not read the 4G signal like it is supposed for some reason. So if you are not in a 5G area the data will not work. I just switched to the non-5G version of the Note 10+. We found this out by switching my plan to one that did not have 5G attached and everything worked just fine until we switched it back to the plan with 5G attached.
