All of the major networks will provide impressive-sounding coverage statistics for their networks. Almost always it’s stated in terms of ‘population coverage’ and will be 97-99% or something like that. Unfortunately, as we all know, the real performance is usually very different.
Population Coverage is a measure of how many houses are in a an area with a signal – and an outside signal at that. If you are sat on the roof of those houses, that’s great!
ParentShield is different – your ParentShield SIM is a true roaming SIM so it doesn’t rely on one particular network. The phone it is in will switch automatically to whichever network provides the strongest signal. You’ll find that those ‘not-spots’ are virtually non-existent in most parts of the country because each of the main networks cover different areas.
Sure there are still some very rural locations where no carrier has a presence, but it’s very rare. Basically, if you have coverage from any of EE, O2 or Vodafone then you will have coverage using ParentShield. We actually use a SIM that was designed originally for the emergency services and essential services and lone remote workers such as vets, engineers and doctors.
