What are the benefits of disabling my SIM for international travel?
1. You won’t be charged for phone calls or texts that occur in another country, since you won’t be able to make/accept calls or send/receive texts.
(iMessage will continue to work just fine as long as you’re on Wi-Fi or using an eSIM for mobile data.)
2. You can relax and enjoy your travels, without feeling distracted by spammy calls, long text threads about plans you won’t be attending, or random wrong numbers. You’ll be “phone-free,” except of course you can still use your phone for your fave apps.
