Simple phones that work on iD Mobile
iD Mobile runs on Three's network.
- 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. iD Mobile's approved-phone list is "advisory". Its staff say many basic phones don't handle 4G calling well.
We can't yet confirm any of the phones we list make calls on iD Mobile.
We've left out 8 phones we can't confirm work on iD Mobile.
