SIMs

[AutumnBlue]

Every 6 hours, I have to take 5 minutes to restart my phone because it disables sim connectivity. This only happened after it got an update, but I can't see how that should affect the phone.

Go to Settings

Select General management

Select Reset

Select Reset network settings

Check the on-screen information and tap Reset settings

Tap Reset

Or you could try reset APN settings

Also make sure sim isn't damaged, make sure there's nothing blocking sim card slot any dust or anything, let me know if any of that helps
