XA2 LoS 17.1-nightly-pioneer - One of sim card slots not support mobile data transmission and MMS
As I remember correctly, LoS asks during the installation which sim card to choose for transmitting mobile data. It isn't possible to choose both. In the original firmware, both cards work without problems.
I tested several versions over the course of several months, they will definitely be:
/device pioneer /version lineage-17.1 /date 2020-11-26 /kernel default from this LoS
I have a feeling the feature has not been working for a long time on every version of LoS 17.1
I don't use any Open GApps.
The problem exists from the first run and clean installation with default settings
Could You check and resolve this problem ?
