I don't know my friend, I bought it for a friend using it in the Middle East.

Yes it did in the USA. Had it for two months dropped it in a puddle and speaker quit working, currently at the factory hopefully it gets fixed, not very happy right now with a phone that was suppose to be indestructible

Yes it does, if it is unlocked by AT&T it will not work. But factory unlocked will work with any GSM carrier.

It should because it's GSM unlocked. It will work on any GSM network. GSM was the global network introduced first by AT&T. Check to see if you have a GSM network provider.

Sorry, I don't have ATT. As a carrier, however the unit does handle all 4 frequencies so it is LTE capable.

No. Even tho it is unlocked it may/may not work with 4g since that is an exclusive Verizon phone. I have att and my 4g doesn't work, so I called about it and that's what was told to me. There is a possibility that you get one that will work but chances are that you won't.

It will work with all carriers but it does not do 4g and it baresly does 3g, the data is extremely slow and qas quick to glitching. (This was my experience, it was not good. I returned it within 2 weeks)

It for sure works with 3G.... I don't have 4G in my area so can't say for sure about that.

Could never get it to work with ATT 4g tried 2 different usb card went back to really old 3g card and it worked. As for UK I think your band frequencies are different so I would guess no this wouldnt work for you.

On my phone it will take it from 2 bars no 4 and it will give me 2-4 bars 4g. But in some spots even with booster and antenna i get nothing but that is just at&t; for you

This unlocked phone should work on any GSM system (att , T-Mobile etc ) regardless of it's original system . I get 2G and 4G on this phone with T-Mobile.

It works on 4G as well as 3G and I am very happy with mine. I hope this helps you.

If the phone is fully unlocked or locked only to ATT then there is no reason for it not working. I personally have done it with three android phones to date and they all work. I do get 4g in my area but I think the I4 is limited to 3G.

I cannot verify that this phone works on 4G. In an area that uses 4G, it says H+ where the 4G would be. The phone works very well for my wife, though. I would recommend if you purchase it, that you have your phone service co. email to you the instructions to set up data, sms, wifi, etc. Hope this helps.

the 3G network of AT&T; is WCDMA, and this phone support WCDMA, so it will still work with your SIM card

Yes, AT&T; SIM card does work on this phone. This phone does not allow you to save your phone numbers on the SIM.

It should work on 3G network. I do believe 4G also supported but not 100% sure. Sorry for not being clearer.

It will work for your phone yes, but it will not boost the 4g network signal. It will boost EDGE network signal on your phone which will give you network and call access, but it will not be thru the 4g network. I hope this helps. I have been using this device for the past 6 months and being able to use phone and internet in complete dead-zones on ATT using my Note2
