Cannot call since the upgrade to 6.6

Apps & Core Settings
1

I have FP4 and after the upgrade to 6.6 I cannot make or recieve any phone calls. If I try to call, it’s silent for a couple of seconds, then it goes back to phone app. If someone calls me, it doesn’t ring nor it says that the number is not available at the moment. It just stops.
I tried Fossify Phone and native Phone app. Same results with both.
I checked APN and all is correct.
I tried VoLTE and also nothing.
I tried restarting the phone and flight mode. Still no change.
Sms works, mobile data works.
As if it cannot establish the connection for a phone call.

Any ideas or workarounds? I kinda need my phone to be my phone :sweat_smile:

Update: it was SafetyNet. Somehow SafetyNet blocked my calls in both directions. Should I file a bug report?

Update 2: if I turn SafetyNet back on it works as expected.

I am having a same issue after had a 6.6 update. The call dialer cannot connect to mobile service. Any fix on this?

How can SafetyNet be enable to allow phone calls?

Settings / microg settings

Do you use an eSIM or physical sim?

I use a physical sim. Somehow I got the problem resolved by reseting my tmobile APN settings. It is all working now. Thanks.

Excellent, yes that was going to be my first recommendation on places to check. Calls now are LTE or 5G, both of which will require the APN to be correctly set.
