Does the Doro Leva L20 work on Three?
Yes.
WorksThree's own device support page lists 4G Calling (VoLTE) as supported.
Nothing on Three's published plans affects this pairing right now.
This comes from a network list, the network selling it, a maker statement or an owner report.
Three (UK)
- 3G: Switched off (November 2025)
- 2G: Three has never had a 2G network, so calls need 4G Calling (VoLTE)
Doro Leva L20
- 2G: GSM 900 / 1800
- 3G: 900 MHz, 2100 MHz
- 4G bands: 1, 3, 7, 8, 20, 28
- 4G Calling: yes – Doro's UK spec sheet lists VoLTE: Yes, and Three lists 4G Calling (VoLTE) as supported.
The same applies to networks that run on Three: SMARTY, iD Mobile. Smaller networks sometimes handle 4G Calling differently, so check with them too.
Other networks in the UK
