On some t-mobile phones you can use your cingular/at&t sims card,but on some phones after putting a t-mobile sims card in a cingular phone may cause the phone to lock up.....BUT u can unlock your phone by calling your network from another phone or logging on to your account on the internet(I PERFER CALLING YOUR NETWORK).You can also unlock it but putting another cingular sims card back in a cingluar phone then your phone should work correctly if still locked call your service provider but your t-mobile phone shouldn't get locked if u put a cingular sims card in it your phone should work perfectly fine but if not call u service provider.
If you are trying to use the T-Mobile phone with your Cingular SIM, and maintain your Cingular service, you will have to call T-Mobile to get a Subsidy Unlock code, and unlock the phone to be used with Cingular's service.
yes you can, all u have to do is call the company and tell them to unlock the phone then it sould work
tmobile usually locks their phones, so you would have to call and get it unlocked. Cingular doesn't usually lock their phones though, so the tmobile card should work in a cingular phone.
you cant. tmobile sim cards only work in phones with tmobile service providers. however you COULD unlock the phone.
