i have a t-mobile phone with an att sim card, it says i need a subsidy code,anybody work for t-moble or att that knows
If you had an account with T-Mobile that you paid-in-full they will give you the unlock code through customer service.
I don't work for either company, But what I do know is once you have an active account with att you can take your sim card and put it in any att phone and it will work. I honestly don't believe you can switch phones like that with out having an active account Good Luck
Hi Lawson The T-mobile phone is sim locked, what that means is that the phone will only work with a T-Mobile sim. Depending on the model and make of the phone, there are different ways you can go about unlocking the phone to work with the att sim. You can get the subsity code for free from T-Mobile if you have an current account with them and have been with them at least 90 days. If you do, phone them, request the code, reason is that you will be travelling out of country and want to use that contrys sim. If you do not have a t-mobile account, find a freind that does and have them call. Without you listing the make and model, I can not tell you other ways you might go about getting it unlocked
