Unfortunately, I bought S4 for use overseas and on a services other than AT&T; network. It worked with no issues. Regards

The phone is capable of working with T-Mobile LTE. To my knowledge, there are no separate versions for different carriers. I ordered mine online unlocked and I have successfully used it with T-Mobile, MetroPCS, Wind in Italy, and TIM in Italy. Most likely you have some wrong parameters specific to AT&T; still in the phone. Did you try resetting it? If you can, just stop by at a T-Mobile store and they should be able to fix it for you.

I am just wondering if this phone will get LTE with AT&T; or T-Mobile? I read on another comment that it would only get 3G service and not 4G or LTE :/

Can be used on AT&T; and T-Mobile network. Will not work with Verizon or Sprint network.

I'm using this phone with Straight Talk (on AT&T network) and the phone functions, but I'm not getting an LTE connection (only HSPA). Working to resolve the issue.

Nope, it will not. It is not compatible with 4G or LTE. I tried it. They said it would on here, but it doesn't. Don't get fooled and waste your money.

Only works on GSM networts like T-Mobile and ATT&T.; Check with Straight talk.

Best to ask them.... we only provide hardware. You should really call the carrier/service provider to see if this unit will work on their network.

I am not using AT&T, I am using lycamobile its working fine. But observed that some signal drop some times, i am not sure this problem is with phone or network.

No LTE with AT&T here, just 4g. But your local tower could be different. Verizon appears to work with LTE.

Hello Curious, A co-worker had a similar device that would not work with AT&T; but did work on the Sprint network. Apparently there is some internal difference, I would contact Wilson directly to see what product they recommend for your particular carrier. Hope this helps.

I'm unsure I bought it to work on T-Mobiles HSDPA+ (4G) 42.2 Mbit/s network as I wasn't sure if their new 4G LTE was up and running in my area. Also it may depend on the carrier your using as ATT and T-Mobile may operate on different radio frequencies. If I remember correctly ATT had a version for them that was 4G LTE, the LT30at, their previous was the LT28at I think. I don't think any other US carrier had an official 4G LTE xperia. Though T-Mobile is getting the new Z soon. No Sprint or Verizon capable Xperia in years that I know of. Also there may be other versions that would work. You may want to double check on websites like phonearena, or one of the Xperia forums.

No this cell not work on lte or 4g, by the way the 3g works only on a few frecuencies, check your provider and the bands of this cell, becaus you can get an edge service only if you not check right

AT&T; uses the same 700mhz LTE frequency, and I would guess that it would work. I would contact Wilson customer support before buying it though, to make sure. I contacted them and had a great experience. Also, just an FYI this does not work with voice as voice over LTE is not used yet to allow for network redundancy.

Will not support AT&T; LTE. But it will support Verizon. AT&T; uses different frequencies for LTE.

with c6603 you will not get 3g and not even dream about LTE. im in NW florida and i tried at&t, tmobile and net10. all i got is 2g (edge) after change APN set many times, nothing... probably somewhere in the world yes but not in US. in my experience

I use my phone on a GSM network in Jamaica and it works perfectly. AT&T is GSM so it should work.
