[Q] USA vs. UK - General Questions and Answers

I am moving to the UK in a few weeks. I am currently with T Mobile USA and was wondering if anyone knew how will my devices work over there. I know i will need to get them unlocked but i have a few 4g phones and dont know if they use the same service there. I have the following devices, MyTouch 4g, Samsung Vibrant and Samsung Vibrant 4g, galaxt tablet.
Thanks in advance.

I believe you can call t mobile and let them know youre moving and they will let you know what to do.. If I'm not mistaken the gsm band is different in uk so they csm tell you if your phone if compatible..

[Q] Can GS 4G do TMo & ATT 3G?

Hi, am leaving Sprint. Looking to get a used phone (no contract), that will work on monthly plans like TMo prepaid, Straight Talk (ATT)) w/out a contract. I'm reading good things about both the older Vibrant (SGH-T959), and the newer 4g (SGH-T959V). It's clear from my research that people are successuflly unlocking and able to go back and forth between TMo and ATT SIMs on the older Vibrant. What isn't clear to me is can this be done on the newer SGH-T959V?
Again, I don't care much about 4g. 3g on AT&T is fine. But while on TMo, the 4G would be nice.
Thanks!

U can use 4g on tmobile but on AT&T you can only use 2g/edge no 3g

Thanks Brandon. I will then pick up a used, older SGH-T959 (Vibrant), unlock it, and then enjoy the 3g flexibility of both ATT & TMo. It's strange, the T959V is supposed to support the same ATT 3g band as the regular T959, but I can't find proof of this anywhere.

that's affirmative, i'm using it right now with 3G and is very fast
Yes, I also can confirm the 959V (T-Mobile 4g) is 3g on ATT and is very fast.
Not true...

I have SGS4G and am using ATT. I have 3G with no issues...
posted original question here by accident
I am using unlocked 4g on Cincinnati Bell wireless and the 3g works fine.
However I have not been able to get 4g at all on my phone. When I put a Tmobile sim in it works fine one 4g.
I get a little over 2 mbps download on Cincinnati Bell 3g.
You can just unlock it, I'm using mine on att right now. Only thing is you have a backup sync for T-Mobile instead of att.

Yes it can.
I tried my friend's AT&T sim card and it worked with 3G.
Hmm, has anybody gotten 4G on this phone with AT&T?
Does 4G work with an unlocked SGS 4G on AT&Ts network?
no.

3G on AT&T will only work one one of the two UMTS bands: 1900 MHz.
Note that the Vibrant 4G doesn't have the 850MHz band (the other band that AT&T uses for 3G data.)
I've seen a posting that there's a way to activate the 850MHz band, but I have not verified that this works. If anyone has got this working so you're working on both bands on AT&T with your Vibrant 4G, let me know.
As an addendum to my own post, looks like the consensus is that while the Vibrant has an option of selecting the 850MHz UMTS band, it actually doesn't enable anything:

Has anyone speed tested (w/ dual core tele) ST tmo?? Please share speed test results?? ..speed test (dual core) on Simple Mobile 4g plan appreciated too. I'm looking for these comparisons...Help please?
TIA!

Anyone using a euro Sensation in the US? Moving to the States, need advice!

anyone here use a euro Sensation in the US? what carrier are you using and do you get 3G?
thank you in advance!
The US and EU are the same so you shouldn't have any issues and it will run at 4G.
And btw, Welcome to USA
Sent from my Sensation using XDA App
If it uses the same bands as the US version it should work for T-Mobile and Simple Mobile(prepaid mvno that uses t-mobiles tower).
Both gets 4G where its available.

yup tmobile sells z710e and from your signature i can tell yours is z710e so there you have it!
Europe has GSM band. Don't think they use that in USA. But I heard att and T-Mobile should work though.

I took my EU Sensation to Florida in Septemeber - bought a tmobile SIM and had it up and running within a few hours. The initial problem that I had was that my phone was registered with tmobile in the UK - so the tmobile apps didn't work in the US with the help of tech support they registered the phone with themselves and I was able to use the tmobile apps including the $1.34 for internet per day which you have to activate daily.
Of course, now that I'm back in the UK - my tmobile apps don't work here but I don't need them here.

I believe that T-Mobile US is the same as Euro based phones, i.e. uses the same bands, 900Mhz, and AWS. Bell Canada and AT&T US use 850MHz which isn't compatible. They're both GSM for Voice, the data frequencies are different though.
Please correct if I've got that wrong. I know I looked up some of this and it all got scary.
There are various posts on the subject.
I found this so you can plug the county in and see what's compatibile.
(850MHz) http://www.gsmnation.com/htc-sensation-z710a-3g-850-1900-mhz.html
(900MHz) http://www.gsmnation.com/htc-sensation.html
EDIT: Why is life so complicated ? I thought we had it simple now, guess again. At least Pan Europe there is one standard (or so I believe).
Have fun.
thanks for all your input guys! i guess T-Mo is the way to go. my wife said that when she was back in the US (Hawaii and NY), she was not getting 3G on T-Mo while she was there.
could that just be that we don't have a 3G plan?

Sim unlock galaxy s3 on verizon? :(

Can someone please help me with me new galaxy 3s? I just bought it from USA and i want to use it on Greece but it is locked on verizon.... What should i do?
That's an 800MHz/1900MHz CDMA phone. If Greece is like the rest of Europe and uses GSM, the phone doesn't have the radios to work there, so you can't use it. (The SIM is for data, not voice, but you need the basic connection to the network for it to work, and a CDMA phone won't connect to a GSM network.)
You should sell the phone to someone in the US (who wants a Verizon phone - it can't be "unlocked" for other carriers) and buy the GSM version of the phone.

New Verizon phones have worldwide roaming ability (including the S3) so it should work on any GSM carrier outside the US.

It is a sch i535rwb 4g phone. How can i check if it has a worldwide roaming phone? Also what should i do so that i can use it in Greece?
You need the SGH T999 (The GSM variant of the SGSIII) The Verizon variant should NOT work in Greece on a Greek carrier.

Are you sure for that? If i am not wrong this is an US version too, whats the diference and i can use sgh t999 in Greece?
I used to think it was native but apparently not. You can still enable worldwide roaming though.
Here's the thread, you need to do some hackery

You can just root it and and flash the synergy mod rom and it will work on any carrier
Does it actually have a SIM card slot or just a built in one?
If you're looking to use it primarily in your area I'd look for a different phone - sell or trade this one. I've heard the GSM can be used but that it's pretty terrible and certainly not what you'd want for a primary phone.

[Q] Carrier Trade

I was wondering if you guys could help me understand something as I don't know much about cellular carriers. I currently own a Lumia 920 on att and was looking to trade it for a galaxy s3. I found someone who will trade with me, but he is on Verizon and the phone is with Verizon. I applied on att for an unlock code so that he would be able to use it, but I'm not sure how the whole GSM vs cdma works. What would I have to do to make this swap work if that's even possible?
thanks in advance.
It is cdma vs gsm networks. The gs3 on Verizon can work on gsm networks but was not designed to be utilized solely on a gsm network. I would stick with s phone from your current provider

Sprint S6 work on Verizon - verified?

According to this site http://www.willmyphonework.net/ , an S6 from Sprint works on 2G, 3G, and 4G Verizon. Can anyone confirm if this is true? I know sprint is CDMA but not sure if this still is true or not.
Anyone?

You might get an answer from someone on the Sprint forum, most people here have a branded Verizon phone.
