Reboot your phone

Check your system software is up to date

If your device is an older generation, it might need a software update. Double check if your phone is operating on the latest software. If it’s not, go to your settings and update to the most recent version.

Update your SIM

When was the last time you updated your SIM? If you can’t remember, that’s a sign that you might need an upgrade. They may be small and mighty, but like most tech, they don’t last forever.  If you're ready for a replacement, you can do so instantly with an eSIM enabled phone at Replace my SIM.
