Mobile network operator O2 (Virgin Media) has today begun to notify customers about the next batch of four UK locations to go through their 3G mobile (broadband) switch-off programme, which recently started with a pilot in Durham (here). Norwich, Telford and Guildford will be the next areas to have 3G withdrawn on 16th July, with Torquay to follow on 4th August 2025.
The process, which is due to reach nationwide completion by the end of 2025, should free up radio spectrum so it can be used to further improve the coverage and mobile broadband speeds of their modern 4G and 5G networks. O2 noted how they had already upgraded masts in the new locations ahead of the switch-off. The switch-off will also reduce the operators’ costs and power consumption.
The switch-off means that customers in these locations, including those on O2’s virtual / MVNO operators (e.g. Sky Mobile, giffgaff, Tesco Mobile), will require at least a 4G SIM and handset to continue using mobile data. But they are not switching 2G services off yet, which means that affected customers will still be able to use voice calls and send text messages as they currently do, at least for now – O2 will start shifting customers off 2G during 2025 too, but they won’t be able to completely withdraw it for several years (here).
Known vulnerable customers have also been contacted with an offer of a 4G-ready device “free of charge“, while all other customers who do not currently have a 4G handset or SIM are said to have been offered a new device at a reduced price.
Jeanie York, VMO2’s Chief Technology Officer, said:
“We’re switching off our 3G network to focus our attention and investment on upgrading faster and more reliable 4G and 5G networks that will give our customers a better overall experience.
Following the successful pilot in Durham earlier this month, we will now be switching off 3G in Norwich, Telford and Guildford in July, and Torquay in early August, with the rest of the UK to follow by the end of the year.
While we know that the vast majority of our customers already have a 4G or 5G device and will not have to take any action, our priority is to provide support to those who need it. That is why we are reaching out directly to customers who do not have a 4G or 5G handset, and calling those we know are vulnerable, to provide information about their next steps. It is important these customers upgrade their handsets in order to continue using mobile data after 3G is switched off.”
The main thrust of O2’s national 3G switch-off programme is currently due to begin from August 2025. At this point they will stop announcing individual locations due to the scale and pace of the effort.
