Hello everyone, am using a BB 9850 torch verizon to b precise but I unlocked it so am using it with a deffrent line now. My problem is sometimes if someone tries calling, the fone wouldn't ring out n if I pick the call I wouldn't hear what the person is say until I remove the battery n insert it back. And a friend of mine is having similar problem with is verizon 9930. Pls would really appreciate it if anyone can come to my rescue. Thanks so much.
