My wife's phone no longer recognises its SIM card, or any other. Her SIM card, however, does work in my phone (Galaxy S8).

Her phone is from the US and is currently used in the UK. She was with Sprint/T-Mobile, but her phone was unlocked and now she has a Lebara SIM card that has been working for over a year now.

I believe the update is the cause of the problem as this issue occurred immediately after the update, and we've gone through all of the usual fixes (reseating the SIM card, restarting the phone, clearing SIM card cache, wiping the cache partition, etc.)

Can someone please advise how to fix this as my wife's phone is currently unusable.
