In my previous life before I retired I was part of the team on the Emergency services network when EE won the contract. They certainly left Voda behind who I dumped last year. Surprisingly O2’s coverage was the best in the UK before EE won that contract but not anymore.I went for the EE network only because we were going to do the Islands, and as the Emergency Services 4G provider I understood that they had the best network in remote places, we certainly had an EE signal more often than O2 and Voda.
But if going abroad then Smarty is certainly one we would look at.
