Hi i think your mobile is locked by particular provider. So only it didn't accept your t-mobile sim card. If you need unlock your mobile you can visit this site Theunlockarena.com here you can get the code and unlock your mobile easily. To get the code you have to mentioned which country is locked now,network provider and imei number. Then they send unlock code through email .

You need the T-Mobile settings if you are using a T-Mobile SIM. assuming you are in US as Unicel not over her in UK so the settings are:

T-Mobile GPRS settings (T-Mobile EDGE settings) T-Mobile GPRS/EDGE settings for terminals (e.g., phone handsets). Some items are possibly Nokia-specific. I have found the authentication type can be either Secure or Normal. These settings should be useful for T-MobileWeb users.

APN is the GPRS Access Point Name.
T-Mobile GPRS/EDGE modem settings T-Mobile GPRS/EDGE network settings when using a device as a GPRS "modem", that is, when "tethered" to another device. Examples include connection via Dial Up Networking (DUN) Bluetooth profile, or via Universal Serial Bus (USB). These settings should be useful for T-Mobile Internet users.
