This is a sim card phone, the carrier has to be GSM and as far as I know TMobile has GSM but AT&T; is CDMA, personally I use simple mobile, it is a spin off company (TMobile based), check with the store

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.

In short, no. This phone uses a sim card and the GSM network (T-mobile-AT&T;).

This is a GSM phone and is only meant to work on the GSM networks. It will work on T-Mobile and AT&T.; Worked without a hitch on T-Mobile for me. Just get a sim card from them and pop it in and you will be good to go. Hope that helps.

I am using it on T-Mobile, but I can't imagine that it wouldn't work with AT&T; as they have the wider choice of bandwidths in the US.

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!

Net10 uses AT&T; and T-Mobile. I have Straight Talk which is interchangeable with Net10 and it works fine. I had to return this phone because it would not charge.

It should work on T-Mobile. I am on AT&T and it works they both use the same network.

I know AT&T; did not sell this phone. So I doubt it would work on their network. I think this was exclusively a Sprint phone, I know that is who I had when I bought the phone.

At&T; has real nationwide coverage. T-Mobile is a metro-area carrier, even though they are nationwide. They have no coverage in outlying or rural areas. The box my phone came in indicates it uses AT&T; as a wireless carrier. It also shows it may use T-Mobile. I got my phone at Walmart, so this might not apply to the phones being sold here. One way of telling is to examine the SIM number. The second set of digits indicates the wireless carrier...XXX 141.....141 is AT&T...126; is T-Mobile...When a gsm phone uses both AT&T; & T-Mobile...I'm not sure how the SIM is coded.

No. This is a GSM phone that requires a SIM card. Also, the one I received is only a tri-band GSM. You need a quad band to be guaranteed to work with T-Mobile and AT&T; in all areas of the US. I'm not able to use this phone with ATT in my home area.

I believe yes. I personally use T-Mobile, but when turned on phone first wanted to log in to AT&T; network first & was showing AT&T; logo, than manually I had to use other option to log in to T-Mobile.
