Issue with Dual SIM usage after iOS 16.5

Hi All,

I've been experiencing an unusual issue after the iOS 16.5 software update.

All of a sudden I get a notification that my Primary SIM is no longer active and I notice that it says NO SIM in the Mobile data section as well. I then switch off my mobile phone and switch it ON again and it's back to normal. I don't really think this is an issue with my carrier. This has happened thrice within a week's time.

Just wanting to know if anyone else has dealt with the same problem and if there is a bug fix for this?

Hopefully this wouldn't lead to me losing my contacts.
