You will need to contact ATT for this or seek out an unlock web page on the web. Each phone takes a unique number so their is not a single master code. But I would recommend waiting a month or so as ATT is purchasing TMobile

I purchased a sim card from tmobile to replace my att simcard on my samsung SGH-A707.The new sim card won't work,it sy's incorrect sim and networt lock.

Hello

The sim wont work because it is locked to the att network which means it will only work with att sim cards.

You will have to unlock the phone from the att network before it can work with the T mobile sim card

You should contact your network provider so as to get steps to unlocking your phone from the att network or you should contact a repairer to help you unlock it

Putting existing tmobile sim in atat pantech c740 phone says sim locked

ATT phones are locked to only work with ATT sim cards. You can call ATT for the subsidy unlock code, but since it sounds like you don't have service with them, they might not give it to you.
The other option is to do an online search for the subsidy unlock code your that model phone; there are sites that will give you the code for a fee.

2 Problems..Sim Card Problems

Well, first off, an iPhone won't work at all with a T-Mobile SIM card. American iPhones are locked to AT&T's network -- only AT&T SIM cards will work in them.

As far as activating it with AT&T, make sure that the iPhone isn't connected to the computer while you install iTunes. Once iTunes is installed, connect the iPhone to the computer and iTunes should launch automatically and begin the activation wizard. Just follow the instructions on the screen and answer the questions.
