I followed these steps on my Xperia 1ii and nothing changed (except me having to re-enter all my wifi passwords). I expect the same will be the case for the 10ii.
Can you clarify whether or not VoLTE relies on something being enabled at the phone company end?
The page here on the Sony website implies that it does - if 4G calling or VoLTE isn't available in the settings it says to "contact your network operator".
3G is still operative at our local mast. Now find my wife's main phone on EE, can only do texts, and it seems my Moto has lost calls ability [on 3], since Monday.
Wonder if it's local mast problem, shared by 3 & EE/Vodafone.
Placed the sim in my Moto Smart phone, and it shows this; in that device, texts not working either; have ordered replacement sim. Hope that fixes. Screenshot of sim in my other device.SIM in another phone.
Most dual SIM phones only support 2/3G in slot 2/SD card slot. Can you let me know if the SIM starts picking up service in slot 1 and when selected as the primary SIM in settings?
I was told at the Three shop that there is no "list" of 4G phones that are accepted by them, and if it can do "VoLTE" it should work. You can check my reply to Kate S (from the community support team) for more details of the "procedure" I am currently going through to get my voice calls back working.
I have a similar experience with my Punkt. MP02 phone which was specifically designed to work on 4G Volte networks. I read in another post that it is up to the carrier company (in our case Three UK) to put these phones on a "whitelist" and enable them to work on their network. My phone lost its ability to make and receive voice calls around the time it was said that our local 3G mast was switched off. Live chat today said I should go to the three shop to get it checked out, which I will do tomorrow.
