I can't get incoming calls and text messages with Telecom Tianyi mobile phone.

After all, I suggest you take your mobile phone and card and go directly to the telecom front desk to find the staff. Your card should not open normal communication service for you. I think it's for you to do data business. Go to the front desk to solve the problem. It's blocked. It'll be done in a few minutes. I've met it, too I hope I can help you!
