You need to get the unlock code for that specific phone. You can get it on Ebay (safe) for about 10 bucks. I did it just last week. There are several vendors, don't pay more than 10.00.

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.

I just bought a iphone 3gs and i'm not with att. It's asking me for a sim which i dont have. Do i need it unlock before I can use tmobile. I cant even get in the phone without att sim card.


What are you doing with a phone without a connection? A SIM is a must for the phone to boot and function. Even a dead SIM would do. But SIM has to be in it. So contact the service provider and get a connection (and SIM). Unlocking may not be required as it is a Quad and 3G phone with all the frequencies.

Can I use an AT&T phone with a Tmobile sims card?


I actually work for a cell phone company as a tech....all you have to do is have your ATT phone unlocked! You will need to contact ATT on another phone (not the phone you're trying to unlock!) and let them know that you need an unlock code for your ATT device...they should be able to give you the unlock and instructions to unlock your device...if anything just the unlock code (if you have had previous service or service with ATT)...if they can't give it too you right away on the phone they will have to send off your information to the manufacture and will get you the unlock code within 3-5 buisness days. (if you have had previous service or service with ATT)...I can't stress enough that you must have an account or use to have an account with ATT...they don't do if for free because all carriers are charged everytime they request unlock codes. If they can't get it for you. You can get it unlocked by a 3rd party vendor that will charge a small fee to unlock your device, but make sure your sim card works in it before you leave the vendor to make sure they are legit and actually unlocked it for you! Good luck.

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.

Changed service, can't receive a signal


ATT runs off of the 850 mhz bandwith while tmobile uses 900. The old phone you are using uses tmobiles bandwith and only catches 850 occasionaly. I would suggest trying to get an upgraded from ATT when you signed the contract
