4G US/UK Phone - Android Q&A, Help & Troubleshooting

I currently live in the US, but am planning on moving to the UK in September. Currently I have a Droid Bionic that is old, and I am looking to drop Verizon and pick up Tmo or another contractless carrier until I move. Obviously I want the phone to work in the UK, with EE as well. I am looking to buy a newer phone with a 5" 1080p display, nfc, and a micro sd slot. Any suggestions? I like the the Xperia Z but there are different models. Any suggestions?

Sure along as it picks up the correct gsm networks you will be fine pal

Any suggestions for models of phones?

I think the GS4 should meet your requirements.
Has crazy specs along with LTE.

As my phone is ultimately failing right now, I'm not sure how much longer I can use this phone before it goes out the Window or quits completely. So S4 is out of the question.

Rezound gsm on at&t

I've seen speculation but has anyone gotten 3g working on the rezound with an at&t sim? I'm using this as a backup phone and it would be nice to have some form of data other than WiFi.

I dont think it has the correct 3g bands for att
There is a huge thread about using the phone on GSM bands in the Q & A forums.

Yes I think there are atleast two people who have been able to get DATA working on at&t, but am not completly sure just going on what I was told

XT912 on att network

Att SIM card works on Verizon RAZR! Just needs little modification. Does not even require root! Thanks to the bionic forum

does data work ?
what "little modification" are we talking about
write up ? link ?
The procedure...
Data does work because I get an "H". But i choose to turn off data because i do not want to be billed.
I am on ics.
This is what I did (modified from the bionic forum)
- got an att sim card activated with a basic gsm phone
- turned off razr
- replaced the Verizon sim card with att Sim card
- turned on phone. You will get an "unknown sim card" error. Press ok
- go to system setting>more> mobile networks> select GSM/UMTS
- click back button, select access point names, select AT&T US (wap.cingular)
- press *#*#4636#*#*
- go to phone information, select WCDMA preferred, below it, turn off radio then turn it back on, exit by pressing home
- turn off data sync in the mobile data networks. Also turn off wifi.
- wait up to 30 minutes or more to let the phone connect to the network

I've heard of people getting AT&T text and calls to work on a XT912 but to date, I've not read of anyone getting data to work. Can you confirm that you have working data (without wifi obviously lol)?

Wish mine would cooperate so easily. It's been set like that for several weeks and never connected.
Anyone else successful? I got nada trying this.

I turned on data then I lost the signal. It would not come back even though the phone reads the access point name. I think either AT&T or Verizon saw that I'm using an unauthorized sim card and disabled the signal.

My RAZR gets Mexican signals roaming but would not connect to AT&T.
Got the signal back!

That's what I figured. Cellzealot is working on a hack but it doesn't look very promising - http://forum.xda-developers.com/showthread.php?t=1619563. They do have a hack for the Bionic to use 3G on AT&T. I set my little bros phone up a few weeks ago. Unfortunately, the hack seems to only work on GB and not ICS. Most Moto global phones can be unlocked for AT&T but since the Razr wasn't officially released as a global phone and they basically only announced global support because they couldn't patch it on ICS (my opinion, not confirmed), the Razr is different.

I heard that you only lose data when in U.S., when overseas your (overseas) SIM will work with data.

From the bionic forum is where I saw that moto phones will work if the GSM radio is installed and enabled. Being updated to ics, Verizon enabled Gsm radio to have used as a global phone.

I haven't followed it as closely as I once did, but the Droid 3 is completely hackable because AT&T has a similar device. So I purchased the unlock code, flashed the GSM radio and it was done. TBH created a hack for the Droid Pro that would unlock it (old file, not recently updated) similar to the unlock file that works for the Bionic. They also have a Razr unlock file that I believe changes some settings to GSM (I don't believe it's a true hack just setting changes) but it doesn't unlock data in the US. It only allows data overseas. One user in the thread I linked to reported picking up data in the US but only because he's close to Canada and AT&T was roaming to Canadian towers. That's further proof that Verizon and US GSM networks have enabled some sort of block that is yet to be cracked. Cellzealot is a pretty smart guy. If I had to guess (that is IF it can be hacked), he'll be the guy to do it.
A general consensus across the board is that ICS has changed the radio handling which has made sim unlocking much more difficult and patched previous hacks. Again, I'm just paraphrasing what I've read from Cellzealot. He's your guy for more information.

Are you on ICS? Wont work on GB. Some users report that it shows no service but they can still make calls and texts.

On ICS now but I've tried it on GB too. Never have gotten anything to work. Have done the NV edit and various patches, roms, settings.
I hope cellzealot has an epiphany.

Temp phone for JTAG

I'm going to send my phone put for JTAG soon, and I need a replacement phone. All I have is a T-Mobile sensation 4g, as the DNA is my first Verizon phone. The LTE SIM won't fit into the sensation. Any one have any suggestions?
Sent from my HTC6435LVW using xda app-developers app
You could buy a SIM adapter. However I am pretty sure the T-Mobile phone will not work on Verizon. The Verizon SIM is used to connect to the 4G network only. As far as I know, T-Mobile has not implemented LTE and T-Mobile phones cannot connect to LTE networks. Even if it did, it would not be setup to use Verizon's LTE frequency.

DUH! An adapter! Don't know why I didn't think of that. Thanks, that's probably what ill do. I figured LTE wouldn't work, and I didn't even plan on data working period. But I need to make calls and texts, so in hoping that works. The sensation is unlocked and rooted so in hoping it works
Sent from my HTC6435LVW using xda app-developers app
Even with an adapter, the T-mobile phone with a verizon sim won't work on Verizon. Verizon's network authenticates phones, and only phones that are in its database will work.
After a quick lookup, the Sensation will not work on Verizon. You can give it a try and see however it does not support the CDMA frequencies. This is a GSM phone only. I've attached a network spec and you can see it at the bottom of the picture. Also, Verizon does do authentication

My DNA is out for JTAG now. I picked up a relatively inexpensive RAZR HD on Craigslist for the duration. When I get the DNA back I'll just offload the HD back onto CL or on eBay for as much as I paid or more. Find a reasonably good deal and you won't lose, no big deal.

Tmobile LTE

I'm getting an optimus g soon. It's unlocked so if I pop in my sim card and add the fast.t-mobile apn should Lte work? I live in Vegas and is supported by lte. I get lte with my nexus 4 fine
Sent from my SGH-T999 using xda app-developers app
There was another thread where someone said he couldn't get lte no matter what he did. He tried different ROM/radio combos. I've been using an unlocked optimus g for the past month now on T-Mobile but we don't have lte in Florida yet , hopefully next month.
I hope it works for you because according to the specs of our phone it should.

When i get HSPA, I can pull 13mb/s download, 3 mb/s upload. But the 1900 mhz, is not in all places where I live. So I get those speeds, or Edge. Sucks. I don't recommend trying to pull up Google Map to look for something on Edge, it's slow.

Will my Verizon s4 take an AT&T sim?

I'm contemplating switching to Straight Talk and naturally I want to keep my S4 versus getting one of their phones..is this possible to just buy the AT&T GSM sim from them and use it with my Verizon s4? Or am I doomed to a Straight Talk phone.

I belive it will I just got 2 vzw s4s im going to try and get them working on tmobile I did it with a vzw s3 and note 2 I dont see why you couldent. On note 2 and s3 I only got 2g data. Ive read elsewhere that the vzw s4 will get 3g possible 4g. Some1 correct me if im wrong
Sent from my SGH-M919 using xda app-developers app
I use straight talk (using there at&t version) and it works perfectly. The only thing I heard was if using at&t it might bump you to 2g phone in the states, but I don't think that's true for S4 like in previous models. But I'm not 100% sure.
