I got Motorola Razor V3 phone from T-Mobile couple of days back. I noticed that when somebody calls me, I get "unknown call" on my cell phone display instead caller's phone number. I know the caller's phone number is not blocked.When I called t-mobile customer service, he is saying that this is known issue and he is going to let me know the fix for it in couple of days.Has anyone noticed this problem ? If so, how did they fix it. Do I need to change any settings ?
