I am trying to move to iD Mobile as my phone - Honor Play - is supposed to work with 4G Calling (VoLTE) and Wi-Fi Calling.
I can get Wi-Fi calling to work although it is disappointing that it only works if there is weak mobile signal rather than whenever suitable Wi-Fi is available. Is it possible for calls to go over Wi-Fi rather than the mobile network whenever a suitable Wi-Fi network is available or is how it is working just how it works?
The bigger issue is 4G Calling (i.e. VoLTE). I have found that the phone always drops to 3G when making a call. Also no VoLTE icon appears. Both of these would indicate that VoLTE is not being used. I called 7777 but the person I spoke to said that was correct i.e. they seem to have had no idea what VoLTE is or how it works.
I tried dialing #*#*4636#*#* as I saw in another post and get an error message "connection problem or invalid MMI code" which suggests something maybe wrong...
How can I get in touch with someone to see why VoLTE doesn't seem to be working and try to get it working?
