I can't text anyone or phone anyone. It seems that the Giffgaff network is down. Me and my husand and son have giffgaff and my friend and they are all having trouble getting a signal to fone anyone or to text. We cannot even phone emmergency services if we wanted to! It has been like this now for 2hours today! What is going on Giffgaff? Can anyone help? Does anyone else have this problem or know what is going on?
