What wrong with my Samsung Alpha, it's not receiving calls?

[AC Question]

Samsung Alpha not receiving calls

My brand new Samsung Alpha will from time to time not receive calls or texts with good coverage and never a problem with other phones in these locations. Diverts straight to voicemail but can make outgoing calls at this time just not receive.
I have exchanged the phone for a new one of same and changed sim card.
It is a lovely phone but if this issue persists it will be back for a refund.

Re: Samsung Alpha not receiving calls

Welcome to Android Central! It probably has more to do with your carrier than with the phone. Have you spoken to your carrier about this?

Having the same problem with my alpha. Changed sim cards and still not receiving phone calls at times and other times it fine. All from the same locations.
