There are a number of mobile providers that piggyback on the O2 infrastructure, referred to as Mobile Virtual Network Operators (MVNO’s) in the industry.
Currently the following providers use the O2 network:
– Sky Mobile
– Tesco Mobile
If you decide to get a phone or sim only plan through one of the above providers, you will be able to access the same network as O2 customers, whilst getting the features and service from each respective company.
