I have two redmi phones (both global editions) that were on telechoice. Things have been fine, but in recent months we were finding at home (inner suburbs of Melb) that most of the time during the day we were unable to make calls or could only make calls after 5+ attempts, did not receive calls (straight to message bank), and would drop calls regularly.
I tried to see if there was any network issue with Telechoice and it all looked fine. They did some network reconnection with my number, and there was no improvement.
I shifted to Boost thinking that their wider coverage would help, but it appears not to have.
Just wondering if anyone has any advice. Should activating VoLTE improve things?
I have a Redmi Note 9 Pro connected with Aldi (Telstra) in Brisbane with no problems at all . I bought this phone via Amazon UK , uses MIUI Global 12.01 & Android 11 with Security update 2021-05-01 .
