Simple phones that work on Three

The riskiest UK network for simple phones. With no 2G and no 3G, calls only work over 4G.

• 2G: Off. Three has never had a 2G network, so a phone must support 4G calling to make calls on Three.
• 4G calling for phones they didn't sell: Approved phones only. Three says phones without 4G calling can text and use data but can't make calls. Its device hub lists which phones support 4G calling.

We've left out 7 phones we can't confirm work on Three.
