Mobile phone owners with devices more than 10 years old may need to get a new one as 2G and 3G networks are phased out, a tech expert has said.
The switch off of the 3G network is almost complete after mobile phone operators were given a 2033 deadline by the government, with O2 to switch off its 3G network gradually in the coming weeks.
Gloucestershire-based David McClelland said some older phones, along with burglar and care alarms, will not be able to receive 4G and 5G networks, while others may automatically switch over.
A spokesperson for O2 said it had written directly to its customers to inform them and had advised those with incompatible phones on upgrades “at a discounted price”.
