I have an issue with Jolla C since yesterday:
- mobile data is always grey out
- if I put the sim in Jolla 1, it works
- if i switch from sim1 to sim2 in Jolla c, still does not work
- if i turn down the phone and remove the battery for a while (I believe there is a sort of memory attached to the sim), still grey out

I am running out of options. I am using Jolla C as main phone for couple of days and it originally worked flawlessly but now, no mobile data

Any pointers to help ?
