I have recently bought a CECT 168 cell phone. Whenever I try to insert SIM card in it, the carries never picks up any signal automatically. I have to do it manually by going into the settings. But my friend’s phone picks up automatically. Why is my CECT 168 cell phone not picking up carrier automatically when I start the phone? What can I do about it? I would really appreciate if someone can help me regarding this. Thanks.
