The listing is completely unclear... is this the AT&T-network SIM card, or the T-Mobile SIM card? I need AT&T, T-Mobile will not work in my area.

This is strictly Net10, it's nothing to do with AT&T;, it's actually a Tracphone with different types of contract. If you want AT&T; will need to SAY it's theirs. I have one of these so don't be fooled.

I just went to the Walmart site and they don't mention that little fact until the very end of the description, way down on the page! I would imagine they are getting tons of complaints about this because people will most certainly unknowingly buy it without realizing, and it says there are no returns. How are they getting away with this? http://www.walmart.com/ip/Tmobile-30-Wireless-Airtime-Card/15443357#rr I also looked on the T-mobile site (they are my carrier) and they do have that same plan listed and says it is available exclusively at Walmart and T-mobile, but it DOES NOT say it can only be used on phones purchased there or at Walmart.

I have my account with T-Mobile and I purchased a phone that was set up with T-Mobile. If it is not set up to use AT&T then I think you would have to have Samsong "Unlock" it to AT&T network use, and then flash the ATT software into the devices programming memory ... but just educated guessing here I have never tried it. Good Luck. Mac Happy New Year!

Not sure what do you mean. I just inserted the SIM card and worked. About AT&T, it is compatible with their bands.

The one I received was. I used it on the AT&T; network and just installed my sim card and it worked.

I do not have an AT&T; phone. I went to AT&T; store and bought a SIM card for $9.99 for 1000 texts. It is text only. or 19.99 for unlimited text. It is working without any problems.

If this is an unlocked Verizon device it will not take a sim card. T-mobile is a different network than T-mobile and AT&T.;

While I cannot guarantee anything, t-mobile and AT&T use the same types of connection, so you should just need the right SIM card.

This one does not work with att. This card is a straight talk/T-Mobile but you can buy the straight talk/at Sim card. If you do, be sure to use an att or straight talk phone. Otherwise, you will get a really suckky signal. My personal experience, this Sim worked awesome ( no problems at all) with a straight talk phone. Signal sucked with my T-Mobile phone.

The model number is LT30p Xperia T. I'm not familiar with the AT&T version because I got the unlocked phone, meaning I can use any network.

As others have said, you get a SIM card from whatever provider you want to use. The key is that it must be a GSM provider, like AT&T; or Tmobile. There are also other GSM regional carriers out there but those are the national ones. I found the AT&T; plans better than Tmobile.

I bought an ATT SIM card through the carrier puretalkusa.com. They were also the sellers. It works fine. A word of warning would be that unless you KNOW there is now a service dept to take card of problems on the US version, I wouldn't buy it. Unless it's changed, it doesn't use the type of cord you can get in any Quik Shop. It's a non-standard cord....apparently non-standard everywhere since there appears to be no replacement. When mine dies, my phone will die too.

I've had this phone for quite a while and have not had problems with an att sim card or one card that I use when I go to Europe. It may be a t-mobile issue. With one of our other unlocked phones (an ATZ) we had to buy a special sim card from net zero for it to work. I hope this helps. This has been a great phone for me. I like it better than the 'smart' phone I have in terms of battery life and voice clarity.

I was running mine on ATT...it was unlocked. If it says T-Mobile on it don't get it. Unless you are getting a real bargain on these now you are better getting something else

I think it actually is unlocked. The one I got also has the AT&T logo on the top, but I'm using T-Mobile as my carrier. So there we go. It should be fine.

I think it originally was with At&T. My T mobile sim card worked fine, but I was unable to receive or send Pictures. I called t-mobile and they did something from their end. Now everything with T-mobile works fine. Gary

Hi Tori,I used a T-mobile SIM card with the phone and it worked fine. I have a month to month plan on T-mobile. I think it will work on AT&T;, if you have a sim card because the phone is unlocked. Hope this helps :)
