Which Network Does O2 Use. 0 Deleted User Posts. Shame it is on o2.
Each main operator in the UK utilises different frequencies to deliver their mobile networks with the core networks being EE O2 Vodafone and Three. In a nutshell yes. Sims will clamp onto th old o2 Ireland network all over Southern.
Three Ireland are slowly absorbing the network and creating a new one but there are hundreds and hundreds of Masts that have not been done.
This means you get 4G coverage across 99 of the UK. What frequencies do the different operators use. O2 are just waiting on a date to be allowed to use it but it wont be too long. All others piggyback on their signals.
