To ask the Secretary of State for Science, Innovation and Technology, what steps her Department is taking to support mobile phone owners whose device is not 4G compatible when the 3G signal is switched off.

The government welcomes legacy networks being switched off in a responsible way, as this will free up spectrum for 4G and 5G networks and beyond. Ofcom has published details of how it expects the mobile network operators to conduct the switch off in line with their regulatory obligations. These expectations include providing customers with a minimum of three to six months’ notice of any steps they need to take as a result of their provider switching off their 3G networks; communicating in a clear and timely way, using a range of communication channels to raise customer awareness of the proposed changes; and providing additional support to vulnerable customers.

The mobile network operators have set out advice to their customers on 3G switch off plans on each of their websites.

We will continue to monitor the MNOs’ progress in switching off their 3G networks.
