I joined ID mobile from o2 and honestly it was the biggest mistake I ever made. I was promised by Carphone Warehouse that ID mobile was the ‘new network’ to be on and that the signal and coverage was great. We checked the coverage in my area and it said it was very good.
After a few weeks I noticed that no matter where I went, I only ever had one bar of signal and sometimes maybe none, It is also super slow to load up anything. I travel with work around the world and was promised this was the best network to cover me everywhere I need to go. I cant even leave my own house without having any signal once I go off my home WiFi, never mind try to fly to another country.
I am soo sorry I left o2 and if I could get out of my contract with ID I would. It is a constant struggle to get any signal or have a fast speed on apps.
