Vodafone users are being warned that their mobile phones may soon be impacted by changes.
The phone company has become the first major mobile network to switch off 3G in parts of the country with other networks set to follow. As a result, if you've got an old mobile handset you may soon lose internet access on your device.
According to Martin Lewis' Money Saving Expert newsletter, the switch off is most likely to be an issue for users of older mobile devices and Sim cards that can't connect to newer 4G or 5G networks. Telecoms regulator Ofcom estimates 5.5 million people will be affected by the combined shake-up.
