Hi I get a Motorola Edge Plus phone (XT2061-3) and it’s VoLTE function doesn’t work with Sunrise network: I have enabled the “4G Calling” in phone settings, and SIM status still shows IMS status as “Not registered”.
I understand this could be device compatibility issue with Sunrise network, but VoLTE works fine with Swisscom before I come to Sunrise.
I would like to ask: Is it possible to fix it? Thanks.
