Can't make nor receive telephone calls anymore

Johnny-Bravo

I have have been using Grapheneos for a few months now, and I'm really liking it! However, at the moment I'm experiencing problems with telephone calls via my regular sim card.

I also have an e-sim, which seems to be working fine. I tried my regular sim card on my old android phone, and there it was working fine too. But on my Pixel 6a with Grapheneos, the sim card gives me mobile data connection, but I cannot make or receive any phone calls anymore.

This problem started only recently. Last week, when I could still make and receive phone calls, I noticed some weird silent gaps in my phone conversations. But as of today, making or receiving telephone calls through my regular sim card just isn't possible anymore.

Johnny-Bravo try restarting and make sure your phone is up to date.

You can also check with your provider to see if they see anything on their end or have any suggestions. It's not very likely that calls would work one day and not work at all the next.

You can also try resetting your mobile network settings from the owner profile in Settings > system > reset options

I'm not sure whether the problem is in my phone (hardware), or in Grapheneos. If nobody else recognizes this issue, I'm afraid I'll have to reinstall Google stock OS (not looking forward to that), and see if the problem remains.

Did you try your sim card in another phone?

Michiel Yes I did try my sim card on another phone, and it worked well.

other8026 Thanks for your help! Restarting my phone didn't solve it. But resetting my mobile network did! Much appreciated!
