I have both Tripletel and Hot Mobile. I have the same issue with Tripletel but Hot Mobile makes me more issues for phones being incompatible. I’ll try using this script to enable VoLTE. Thanks!!

on the mitmachim thread, it seems that it doesnt always work with Hot. Try going to engineers menu >ims>common>operator code and then scroll down to the bottom and click on not in list and by operator code textview, write 172 then set and restart. If it doesnt work then try thisVoLTE on Qin F21 Pro - - No Root Required - Guides / Android Guides - JTech Forums
