What is causing my Skype calls to drop on my Verizon iPhone?
Unfortunately, Verizon’s CDMA network cannot maintain a data connection and incoming calls to your mobile simultaneously. So when you receive a call to your Verizon phone, your data connection will cut out. This will automatically end any Skype calls you are on and sign you out of the Skype application until the voice call ends. When the call ends, Skype will reconnect itself automatically..
