Hi,I bought my phone SIM free in Thailand. I had WiFi calling there with
local SIM but now I brought it to the UK it does not work. It is enabled
but no SMS or calling possible.Please tell me how to get this feature
working with O2 SIM.Thanks and r...
I know how to turn it on. It is enabled in the settings but it doesn't
work. Is the problem because its not O2 handset? How can I make it work,
can O2 activate it, is it something to do with my SIM or account. I have
note 20 ultra
