The most frequently forgotten items when packing for international travel include phone chargers, power adapters, and the quiet confidence that everything will work out fine. The chargers and adapters can be purchased at airport shops for three times their normal price. The confidence cannot be replaced at any cost.
Technology has made international travel simultaneously easier and more complicated. Easier because maps exist in pockets and translation happens in real time. More complicated because all of this depends on batteries that die, connections that fail, and settings that nobody remembers changing but somehow got changed anyway.
The following preparations won’t guarantee a smooth trip. Nothing guarantees a smooth trip. But they will prevent the specific type of distress that comes from staring at a dead phone in a foreign airport while the taxi driver waits and the hotel confirmation exists only in an inaccessible email.
1. Download Everything While You Still Have Wi-Fi
The assumption that internet access will be available upon arrival has ruined more first days abroad than jet lag. Google Maps offers offline downloads for specific regions, a feature that exists precisely because the company knows what happens when someone lands in a new city without connectivity. They’ve seen the panic. They’ve built a solution.
The process involves opening the app before departure, selecting the destination city, and downloading the map data to the phone’s storage. This feels unnecessary while sitting at home with fast Wi-Fi. It feels like genius while navigating a subway system in a language you don’t speak with no signal whatsoever.
Google Translate follows the same logic. Languages can be downloaded for offline use, turning the app from something that requires constant data into something that works in the back of a taxi heading somewhere you can’t pronounce. Download the languages you’ll need. Download a few you probably won’t. Storage is cheap. Being unable to communicate is not.
2. Sort Out Connectivity Before You Leave the Ground
The traditional approach to international phone usage involves landing, finding a mobile shop, presenting documents, waiting in line, and eventually obtaining a local SIM card. This process assumes that the shop is open, that the line is short, that the staff speaks a common language, and that nothing else requires immediate attention. These assumptions fail with impressive regularity.
A better approach involves arranging connectivity before departure. An eSIM for travelers can be purchased, installed, and activated without visiting any physical location. The technology is embedded in most modern smartphones and allows data plans to be downloaded directly to the device. Purchase happens online. Activation happens via QR code. Connectivity begins the moment the plane touches down.
The alternative involves hoping the airport has free Wi-Fi, which it might, or hoping roaming charges won’t be catastrophic, which they will be. Neither hope has a strong historical track record.
3. Back Up Everything to Somewhere That Isn’t Your Phone
Phones get lost. Phones get stolen. Phones fall into bodies of water that the owner had no intention of entering. These events become significantly worse when the phone contains the only copy of passport photos, hotel confirmations, flight itineraries, and emergency contact information.
Cloud storage exists for precisely this reason. Before departure, confirm that important documents have synced to iCloud, Google Drive, Dropbox, or whichever service maintains copies of things that shouldn’t disappear. Take photos of the passport, the visa if applicable, the credit cards, the travel insurance policy. Store them somewhere accessible from any device with a web browser.
Some travelers email copies to themselves. This works. Some print physical copies. This also works. The method matters less than the existence of a backup. The worst time to discover that all important information lived only on a now-missing phone is any time after the phone goes missing.
4. Check That Your Apps Actually Work
Banking apps frequently require verification when accessed from new locations. This verification often involves sending a code to a phone number that may not work abroad. The bank considers this security. The traveler, standing at a foreign ATM with a frozen app and no access to cash, considers it something else entirely.
Before departure, open every app that might matter during the trip. Banking apps, airline apps, hotel apps, the app for that thing you booked three months ago and forgot about. Update them if updates exist. Log in to confirm the passwords still work. Add authenticator apps to a device that will definitely travel with you.
Some countries block certain apps or websites entirely. VPN services can bypass these restrictions but should be downloaded and configured before arriving somewhere that blocks VPN download pages. The irony of needing a VPN to download a VPN is lost on no one who has experienced it.
5. Solve the Charging Problem Before It Becomes a Problem
Different countries use different electrical outlets. This fact surprises an astonishing number of travelers each year, despite being easily researched and entirely predictable. The United Kingdom uses one type. Continental Europe uses another. Australia appears to have designed its outlets specifically to confuse everyone else.
A universal adapter handles most situations. These devices accept plugs from various countries and output to various sockets, solving the problem for anyone who remembers to pack one. Forgetting to pack one leads to purchases at airport shops, where the markup suggests the adapter is made of precious metals rather than ordinary plastic.
Portable battery packs extend phone life during long days away from outlets. A dead phone in a foreign city creates problems that range from inconvenient to genuinely concerning. Navigation stops. Communication stops. The ability to call for help stops. Carrying a backup battery prevents all of this for the cost of a few extra ounces in a bag.
The Underlying Principle
Each of these preparations shares a common theme: solving problems before they happen costs less time, money, and stress than solving them after they’ve already begun. The ten minutes spent downloading offline maps prevents the hour spent wandering lost. The small fee for an eSIM prevents the large fee for emergency roaming. The habit of backing up documents prevents the crisis of losing them.
Experienced travelers perform these rituals automatically, the way they check passport expiration dates and confirm visa requirements. The tasks feel routine because the consequences of skipping them have been learned, usually the hard way, on previous trips that didn’t go as planned.
New travelers get to decide whether to learn from the mistakes of others or insist on making their own. Both approaches lead eventually to the same destination: a carry-on bag that contains not just the usual items but also a portable charger, a universal adapter, and the quiet knowledge that at least the technology has been handled, leaving room to worry about everything else.
