My curve 9360 stops receiving calls every couple of days
 

My curve 9360 phone stops receiving calls every couple of days. I didn't know this until my wife called me on my other phone asking why she could not call me on my BB. When I checked the BB, the signal was full strength. And I could call out without any problems. After I made a call from the BB, it started to receive calls normally. It still receive emails though. This has happened every couple of days. Is there anyone having the same problem?

Thanks!
