I'm currently on holiday in Spain and I have not had a phone signal at all since I've been here 3 days ago. I've tried turning off my Wi-Fi and turning on airplane mode for 30 secs and it briefly gives me a signal then goes again! Obviously everything is fine while I'm connected to the WiFi but once I'm not I can't do anything even though my mobile data and roaming is switched on. Can anybody help me please?
