I recently bought a Sony xperia xa1. Since the very beginning I had problems making phone calls over Skype using my broadband data. I use Skype often ringing abroad and it's very frustrating. Whenever I try to make a call I get disconnected because 'Internet connection is too weak'. I could have 4 bars of signal, yet I can't make a call. There is no problem using WiFi though. Is this a device fault?
