Thank you for the info but I sent the phone back the the seller. My wifes best friend has a BB Pearl 8100 Team Mobile. If you can unlock that phone so I can use it with my at&t 3g sim card I will diffinatly pay the 15.00. When and if i start using the phone, I know it has to have a data plan. But do you use airtime just making and taking calls,or recieving and sending messages. I phone is from work it has s data plan but not allowed to use it.+6
