Is 3G being switched off?
On our network it already has been. UK networks are retiring 3G (and eventually 2G) to free up spectrum for faster 4G and 5G.
What that means for you:
- Data and calls run over 4G and 5G.
- Your phone needs 4G calling (VoLTE) to make calls. See How do I check if my device is 4G-VoLTE compatible?
