A Weird And Infuriating Bug With Two Sim Cards Active At Once

[qqwwee123]

Hi!
So everything was working nice until today. I've got two sim cards mounted into my device and configured as
Slot 1: T-mobile card, used for calling and texting
Slot 2: Orange LTE card, used for internet connection

The thing is: When both of them are running at the same time the person I;m calling/calling me using my Slot 1 card can't hear me. When I disable slot 2 card (internet connection) it's working fine, and the person on the other side can hear me loud and clear. Then when I enable slot 2 card the problem is back.

Soft version: 6.5.19 from xiaomi.eu

How can I fix this?

I stopped reading after the "Slot 2" line. Use your data plan SIM on slot1 which is capable for LTE connection and your calls/text SIM on slot2. Slot2 can only use 2g and not LTE network. You can't change that.
