Hi,

Had my iD SIM for about a week now. I'm aware that Three only broadcasts VoLTE on Band 20 (800 MHz). One thing I'm noticing is that if both LTE bands are available, I'm tending get Band 3 i.e. no VoLTE. In areas with limited Band 3 but good Band 20 the phone is constantly switching between VoLTE and UMTS (I.e. 3G) I tested this on my partner's phone and the results were the same.

E.g. Currently I'm in Lancaster City Centre, on 4G but not on VoLTE. Anyone else experiencing this?


Hi,

What phones are you using?

Cheap Chinese model and a Moto G4 (which doesn't support VoLTE). Irrelevant though as I know that iD is not utilising Band 20 as much as it could. Plus the Umidigi worked flawlessly on EE 2 weeks ago 😐
