Security update is stuck on pause, please let me know how I can download the update on my iwatch SE.

Thanks for the help.

Have another question.

Last week, while on a trip to another county in Florida, my iPhone 12 mini suddenly lost cellular connection/data. iPhone instructing me to get cellular plan.

5 Hours later with no phone connection, arrived home. iPhone 12mini, connected to home wifi automatically. So far, cellular issue seems resolved.

Big question, will this happen again?

Any idea as to root cause?

Thanks.
