I’ve noticed that my phone experiences frequent (like 5-10 times a day) freezes whenever I am either roaming or have a secondary line activated on the eSIM. It’s fine when I’m at home. But when roaming it will freeze randomly and need a hard reset (sometimes 2) to recover.
iPhone 12, iOS 15
Hi clivefromottawa,
We see your iPhone is sometimes not responding when you're roaming or using your second line. To clarify, are you internationally roaming? Also, you mentioned it works as expected when you're home. Are you on Wi-Fi then?
Which iOS version are you running under Settings > General > About? Updating to the latest and then checking for carrier updates would be a great start for this. Be sure to back up first:
Update your iPhone, iPad, or iPod touch - Apple Support
Manually update your carrier settings on your iPhone or iPad - Apple Support
If that doesn't help, you might also want to check Settings > Battery > Battery Health. Do you see any alerts there? iPhone Battery and Performance - Apple Support
Best wishes.
