Okay, if anybody facing problem with mobile data. I had to reflash system. But first i checked version of Android in Emma. My version was .70 in the end. 2 updates away from 62.0.A.3.109. I flashed Android with version 62.0.A.3.109, went thru system etc. Then flashed once again Sailfish OS and now works like a charm! (on sim1 slot) @flypig would be nice to precise what version should be in installed before flashing Sailfish - if thats the case.
