Travel and Public Wi-Fi


Travel puts your devices in unfamiliar networks, crowded places and other people's hands. A little preparation before you leave, and a few habits on the road, mean a lost phone or a dodgy hotspot is an inconvenience rather than a disaster.

About 10 minutes to read20 minutes before each tripBeginner

1Prepare before you leave

Do this
  1. Update everything and back up your phone and laptop (Module 3). If a device is lost, you lose the device, not your photos and files.
  2. Make sure Find My (Apple) or Find Hub (Android) is on, and that you know how to use it from someone else's device.
  3. Check you can sign in to important accounts without your usual phone number. Text codes may not arrive abroad: use an authenticator app or passkeys, and pack your backup codes (Module 1).
  4. Take only the cards and devices you need. Leave old laptops, spare cards and documents you won't use at home.
  5. Save your bank's international fraud number, your mobile carrier's number and your embassy's details somewhere you can reach without your phone.
  6. Turn on bank and card alerts so you see any unexpected charge straight away.
Good to know

Border officers in many countries, including the United States, can ask to inspect phones and laptops. Travelling with less personal and work data on your devices, and with everything backed up at home, reduces the impact of any inspection, loss or theft. If you travel for work, follow your employer's travel guidance.

2Use public Wi-Fi carefully

Most websites and apps now encrypt their connections, so public Wi-Fi is far less dangerous than it used to be. The bigger risks today are fake networks with convincing names, and sign-in pages that ask for more than they should.

Safest
Your phone's mobile data or personal hotspotUse it for banking, work and anything sensitive.
Good
A trusted VPN on public Wi-FiA reputable paid VPN, or one provided by your employer, encrypts everything between you and the VPN. Avoid unknown free VPN apps, which may collect and sell your data.
Take care
Hotel, café and airport Wi-FiFine for general browsing on encrypted sites. Confirm the exact network name with staff, and be wary of two networks with almost the same name.
Do this
  1. Turn off auto-join for public networks, and “forget” them when you leave.
  2. Never enter card details, passwords or personal information into a Wi-Fi sign-in page beyond what you'd expect: a room number and surname, or accepting terms.
  3. Turn off file sharing and set AirDrop or Quick Share to contacts only or off, so strangers can't send you files.
  4. Watch for certificate or security warnings in your browser on public Wi-Fi. If you see one, disconnect.

3Charge safely

US government agencies have warned against using public USB charging ports, because a tampered port or cable could in theory be used to attack a connected phone. Real-world cases are rare, but the fix is easy.

4Guard your devices in public

5Avoid shared computers for anything personal

Computers in hotel business centres, libraries and internet cafés may record what you type. Assume anything you do on them could be seen.

Travel is also a favourite theme for scam messages: fake booking changes, delivery notices and QR codes on parking meters or tables. Module 4 covers how to handle them.

6If your device is lost or stolen

Act fast
  1. From another device, sign in to Find My (icloud.com/find) or Find Hub (android.com/find) and mark it as lost to lock it and show a contact message.
  2. If it's clearly stolen, or holds sensitive data, erase it remotely. You can restore from your backup later.
  3. Call your mobile carrier to suspend the SIM, so nobody can use your number for calls or sign-in codes.
  4. Change the passwords for your email, Apple or Google account, and banking, and sign out of all other sessions.
  5. Tell your bank if banking apps or cards were on the device.
  6. Report it to the local police and get a reference number for insurance. If your passport was taken too, contact your embassy or consulate.
