Sony Xperia 10 iii

[AlanJack_184552]

Model is listed as XQ-BT52 and preferred network type shows 5G/4G/3G/2G

The incompatible list does show a Sony Xperia 10 iii 5G

Would I be correct in thinking that my phone isn't compatible?

Thanks in advance

That does sound to be the case, unfortunately. But the litmus test has to be: have Three now turned off 3G in your area, and if so, are you still able to make and receive calls without issue?

[AlanJack_184552]

No but the phone does say it is connected to 4G and I can still get texts but the call preference & sms preference options are greyed out

[AlanJack_184552]

Also just checked and I can access the internet it is just calls I can't do

In which case it seems Smarty's web page was correct - your phone is not compatible with their 4G calling, unfortunately.

Hmm according to three the Xperia 10 iii IS compatible which suggests it is a smarty problem

[SmartyTrousers]

Correct - Smarty's own web page about VoLTE compatibility states that the devices which are incompatible with Smarty should work on Three itself, and that the issue is specific to virtual networks.
