SIM failure

[Eric8888]

I suddenly saw a sim failure message and lost my network connection. I tried updating iOS, restarting and removing/re-inserting the sim. No luck. What can I do to fix this?

I tried swapping. Both worked! Then I swapped back, both still working! 😅

thanks!

did you try your sim on another phone? test that first

and try using another sim card, active one, on your iPhone
