Would a lg g flex 2 for sprint work on at&t if i sim unlocked it??
yes and no, thats the problem i had with mine, i had a tmobile and at&t sim, everything worked except voice calls in or out....data, mms, and sms worked fine, but no voice, every time i would try to call, the phone would just lose signal...something is locked with it when it tries to use the GSM modem for voice if it connects to a domestic company like AT&T or Tmobile towers, however i know if you take it outside the US it will work...mine is sim unlocked...but until we get a hack out to fix that, then were screwed

I bought Galaxy S2 in China, flashed new ROM, and lost ability to use ATT SIM. Orange SIM works fine, but ATT one simple does not work anymore. I am in US now.
In setting->about phone->status it shows the mobile number from SIM, shows AT&T under "Network", service state "IN service", and "Not roaming".
However, phone does not make and does nor receive calls. If I replace ATT SIM with Orange one, it roams on T-mobile and works fine for calls and data.
Anyone can help?
thanks,
Michael
same here
i have the same problem. my flash counter is at 0. 3g data is down for me, but wifi works perfect. text messaging is also good. but i cant seem to find a fix for this
I recently switched from straight talk to verizon's own pre paid plan after being fed up with straight talk. When I first got the service active everything was fine. I flashed the CM11 AOSP rom snapshot. I then proceeded to try and update my roaming capabilities by dialing *228 which the automated system told me was successful and ever since then my phone will not stay on LTE. It will only goto 3G. If i try to force the lte only mode then my data will work but i wont be able to make calls. I have tried going into stock recovery and resetting factory to try and clear the NV and flashing both the kitkat and lollipop RUU to no avail. Any help would be greatly appreciated.
You might have damaged your Sim card by dialing *228, well I don't know about damaged, but I know Verizon phones locked to their network that uses 4G LTE Sim cards are blocked from dialing *228 because of the reasons you described.

So maybe i need to go get a new sim card then. Thats what i figured hopefully i can get to the verizon store before work and grab one.
Hey,
Were you able to get it working again?
I have the same issue. I dialed *228 like an idiot and my phone activated on 3G and won't get anything else.
I've had Verizon reset the connection on their side and I went to the store and picked up a new SIM but I still can't get LTE. It's driving me crazy. I've tried restoring to a prior backup, factory resetting the phone. Nothing gets me LTE.
Recently purchased the Xperia Z5 (E6653) and I am having some serious issues with calls on T-Mobile USA.
Calls don't dial out (or it takes multiple tries) and calls won't come in when the phone is connected to 4g (LTE); they go straight to Voicemail. I missed about 12 phone calls yesterday - just getting voicemail after vaoicemail till I realized something was wrong on my side. If I toggle off the LTE it drops to Edge (no HSPA+) and calls come in fast and outgoing calls are made with no problem.
I tried to reset the phone, then repair the software with the Sony Companion app. Still same issue. Looked online for the APN settings. Tried various ones. Re-downloaded the Internet/MMS via the phone itself. Same issue. Tried my wife's sim and it was still doing the same. I have a spare 5s and it worked fine both incoming and outgoing calls. So, it doesn't seem like its the sim card.
I have Rev 2 of this phone so I am not sure if that is anything to be concerned about. Am I missing something...any help on this would be appreciated.
Thanks.
Maybe flash a T-mobile firmware with flashtool?
Or Flash 209 firmware meant for usa?
Or wait for someone here that use this phone on T-mobile.
Are you on band 12 LTE by chance
No, it said band 2 with LTE Discovery. I am on the verge of sending it back. Swap it for another one. Let's see.
From what I have gathered/read - it should really be straight forward. Pop in sim, load Internet settings, and it should work on T-Mobile. The APN settings are correct.
Doesn't makes sense for it to completely not work on 4g and go to 2G (Edge) while skipping 3g. I'm wondering if the baseband might just be wonky. I just see this as causing more problems down the road which I don't want from a $520 device.
Any advice is welcome because I am ordering the same phone again. Lemons are always possible.
Could it be possible because I live a relatively rural area (East TN) and the phone does not support AWS? Since it doesn't support T-Mobile VoLTE and doesn't have AWS it is defaulting to 2G? Is this an issue in all areas or just rural? Apparently the E6683 variant doesn't have this problem as it supports AWS.

That means ur phone should work fine with T-mobile,maybe go and get a replacement from where you bought it.
I recently bought an unlocked Google Pixel through Google Store. I use Straight Talk's ATT service and had been using it great (i.e. 4G LTE for data and no problem receiving or placing phone calls) on my old phone, a Moto X 2013. The same SIM card does not work properly in my Google Pixel. I've tried using the APN setttings on Straight Talk's website, I've used settings suggested elsewhere on the internet, and I've used the recommended settings that Straight Talk customer support supplied. Nothing works. Sometimes my phone will receive 4G LTE data, but most of the time it does not. I cannot place phone calls either. My phone shows full service bars with a 4G LTE indicator. However, when I try to dial a phone number, the service indicator kicks down to an H (I'm assuming for 3G speeds) and the call does not go through. When I put the same SIM card back into my old phone, both data and phone calls work. Please help! I have no idea what's wrong. I really like the device, but obviously not having data or cellular service is a dealbreaker. PS When I call Google's support, they tell me it must be an issue with Straight Talk and to call them. Not very helpful.

More than likely it is an issue with straight talk. ATT (which I'm on) usually needs to add your phone to their system. I.e. Registering the imei on their network. I would definitely suggest talking to straight talks customer care and make sure you don't need something like a new sim card or to have the phone provisioned to their network. Also your signal dropping from lte to H is normal as ATT doesn't have voice over lte. Which leads me to believe the phone is doing what it's supposed to but the network is not allowing the call to be placed. Same would go for data over their network.
Hello, I just bought a verizon Samsung Galaxy s7. I am a net10 customer, so to use the phone i purchased the byop kit and inserted the verizon compatible chip and then i go to register the phone with net10, and it says it cant do it, to contact customer service. So I called them and they said that for some reason the imei wont register manually, and that i have to call verizon and see if it was locked. So i called verizon and they said according to the imei i gave them it isnt locked, and that verizon doesnt even lock 4g lte devices. but no matter what i do i cannot get the phone to register with imei. I have even tried strait talk. Another thing to note is that on the verizon website, the s7 isnt listed as compatible device for a byop plan.
So theres no one i can call to have anything unlocked, i cant get my money back from net10, after i called net10 customer service back and told them that verizon said it wasnt locked, net10 CS then stated that the phone wasnt compatible on their network.
A verizon tech said he sometimes has problems registering phone imei's. He said sometimes it goes through, and sometimes you have to keep trying. I really have no clue of what type of process is happening here...
So, i took out the verizon compatible sim, and put in the att/unlocked gsm device sim and then registered that through net10. it actually went through, I now have a phone number and i have basic data, but i cannot send or receive mms. I used the APN settings i found somewhere on the internet for ATT network as they are the only ones that work so far..
The other problem i have is that my phone says the sim isnt from verizon, which im assuming i can just flash the "u" version of the rom to take care of? But am i hoping there is a way to make my phone work in their network so that i can use the intended sim card.
So with all that said I have a couple questions.
1. Why wont my phones imei register on the carrier networks?
2. If i cant get it to register on their networks, is there any way to at least get my mms working?
I find it very strange that no one else has had this problem. I cant find any information as to why the s7's arent part of the byop yet.
Thanks in Advance!
