The Problem
With a standard SIM, you are tied into a single network. When your SIM loses coverage you can't automatically register to another operator and will lose your signal.
The Solution
With WorldSIM, you get unrivalled connectivity across the UK. When the signal from one operator is low or lost, with WorldSIM your phone will automatically connect to another available operator, ensuring you always have a good connection wherever you are.
