I have s22 ultra & it does not have VoLTE even if the SIM card has it
I found a few people they have something called "IMS registration status " is "registered " in the SIM card settings, and they have VoLTE running
While mine is not registered, but I'm sure the SIM that I have, it supports VoLTE, I tested it on iPhone 13 pro max & Huawei p30 pro
Can someone tell me what is "IMS registration status " and how to make it "registered " to run VoLTE??
