I have a problem with my daughters number/ phone. I bought a new phone for her (Samsung trend plus) and upgraded her old number to an option with internet. Since then she can receive calls from all phones/numbers except mine. As soon as I call her, after one ring the call ed is dropped. But she can call me or send me sms. I heard of another person having exactly the same problem (also a TDC number)!. I call TDC, they say there is no problem in their system. I checked my daughters phone- call filters, re-started her phone, mine...all possibilities without success. Anybody is having this issue?
