What I Actually Do to My iPhone Before Every International Trip
I had my phone pickpocketed in Barcelona three years ago — pulled straight out of a bag pocket I thought was zipped closed. I got it back, oddly enough, because a shop owner found it dropped a block away and the thief had apparently given up once he hit my passcode. That trip is the reason I now run through the same checklist before every flight abroad, instead of just packing a charger and calling it done. Here's the actual list, not the generic "update your software" version.
Software and Settings — The Stuff to Do Before You Even Pack
Update iOS and every app before you leave, not at the airport gate on spotty terminal Wi-Fi. Settings → General → Software Update, then a pass through the App Store for pending app updates. Security patches ship in both, and you don't want to be running an outdated version on hotel or airport networks, which tend to be exactly where things go wrong. Since Barcelona, I use a six-digit alphanumeric passcode instead of the default four-digit PIN — takes longer to type but meaningfully harder to guess or shoulder-surf. Face ID handles day-to-day unlocking so the longer passcode barely slows me down. Find My iPhone (Settings → your name → Find My) needs to be on before you travel, not after something goes missing — it's the only reason I got useful location data when my phone was taken. I also go through Location Services (Settings → Privacy & Security → Location Services) and cut access down to only the apps that actually need it while traveling — maps and the airline app, mostly. And I set Wi-Fi Auto-Join to "Ask" under Settings → Wi-Fi → Auto-Join Hotspot, so my phone stops automatically latching onto whatever open network is nearby. A VPN is worth having too if you're going to be on hotel or airport Wi-Fi at all — that traffic isn't encrypted by default, and a VPN closes that gap.
Backing Up Before You Leave — Not During an Emergency
I back up fully before every trip now, either through iCloud (Settings → your name → iCloud → iCloud Backup → Back Up Now) or via Finder on my Mac. This isn't optional in my routine anymore — losing the phone in Barcelona would've been annoying either way, but losing three weeks of photos with no backup would've been worse than the phone itself.
Physical Precautions That Actually Changed After That Trip
I don't keep my phone in an outer bag pocket anymore, zipped or not — it lives in a zippered inner pocket or a small cross-body bag I keep in front of me in crowds. A shock-resistant case is standard for me now regardless of destination, and I add a waterproof pouch specifically for beach or rain-heavy trips. On the SIM side, I switched to eSIM a couple of years ago and it's been a clear improvement for travel — no physical card to lose, and I can add a local data plan without swapping anything out. If your iPhone isn't eSIM-compatible, a local physical SIM still works fine, just make sure your phone is unlocked before you leave home; finding that out at a foreign carrier counter is a bad time to learn it isn't.
Money and Emergency Planning
Apple Pay requires Face ID or a passcode on every transaction for me, no exceptions, including small purchases — that setting is worth checking since some people don't realize it can be loosened. I still carry one physical backup card and a small amount of local cash, because Apple Pay isn't accepted everywhere and a dead battery shouldn't mean you're stuck. If I'm traveling with my nephew and hand him my phone, Guided Access (Settings → Accessibility → Guided Access) locks him into a single app so he can't wander into my email or accidentally buy something. Small thing, but it's saved me an awkward App Store refund request before. For the actual "phone is gone" scenario: Find My iPhone from another device or iCloud.com first, mark it as lost to lock it and display a contact message, and only erase remotely as a last resort since that's irreversible and kills your ability to keep tracking it. I keep a Medical ID set up in the Health app and a list of local emergency numbers saved before I land, and I buy device-specific travel insurance for anywhere I'm bringing gear I can't easily replace.
Quick FAQ
Should I use a VPN while traveling?
Yes, especially on hotel or airport Wi-Fi. Public networks abroad are often no more secure than the ones at home, and a VPN encrypts what you're sending over them.
What do I do if my iPhone is actually stolen abroad?
Mark it as lost through Find My iPhone immediately from another device, then report it to local police and your travel insurer. Erase remotely only if recovery genuinely looks unlikely.
eSIM or local physical SIM?
eSIM if your phone supports it — less to lose, easier to manage multiple plans. Physical SIM is still fine if your device isn't eSIM-compatible, just confirm it's unlocked first.
Conclusion
None of this is complicated, and most of it takes maybe twenty minutes total before a flight. I didn't do any of it before Barcelona. I've done all of it before every trip since.
