Hello!
My question would be that my Mi 9 lite only 6 rings (about 30 seconds) during a call, then ends the call with a "timeout" message. This is also the fault of the original Global Miui. I tried the sim card on another phone (Mi 9 lite), it works properly.
Is there a trick that will fix it?
Thanks

Addition:
Works well on 3g network. Switching to a 4g network is just not good. Do I still need to set up something to work well on a 4g network?
