Why digital safety matters when you travel

When you travel, your devices (phone, laptop, tablet) store personal data and access accounts that criminals can target. An eSIM from AirSims makes connectivity easier — but it’s important to pair it with good cyber habits so your trip stays fun and worry‑free.

Before you leave home - 8 quick steps

  1. Update everything: Apply OS and app updates to patch security vulnerabilities.
  2. Back up & encrypt: Back up photos and docs and enable device encryption.
  3. Use strong authentication: Password manager + MFA for email, banking and cloud accounts.
  4. Install essentials: VPN app, mobile antivirus, and enable Find My Device.
  5. Install your eSIM first: Install your AirSims eSIM profile while still at home where you have a trusted connection - especially handy for destinations which don't allow local eSIM installation.
  6. Download offline: Maps, boarding passes, itineraries and translations for offline use.
  7. Clean up: Remove unnecessary apps and stored payment data; sign out of accounts not needed for travel.
  8. Document copies: Save secure copies of passport and important documents (not public social media).

While abroad - practical daily habits

Prefer mobile data over public Wi‑Fi

Your eSIM data is generally safer than unknown Wi‑Fi. If you must use Wi‑Fi, always enable your VPN before browsing or signing in.

Disable auto‑connect

Turn off auto-join for Wi‑Fi and Bluetooth to avoid malicious networks and pairing attempts. Also be careful of Bluetooth sync with rental cars, personal data can easily be stored in the car's system.

Avoid public USB charging

Use your own charger or a data‑blocker to prevent "juice‑jacking" attacks.

Keep devices physically secure

Use hotel safes, short screen timeouts, and privacy screens. Never leave devices unattended in public.

Common questions

Q: Can I install an eSIM while abroad?

A: Often yes, but we recommend activating it at home first to avoid captive portals, restricted Wi‑Fi, or country restrictions that can complicate activation.

Q: Is a VPN necessary if I use an eSIM?

A: Depends on the country and data you are accessing. An eSIM secures your connection to the mobile network, and a VPN adds region/country changing ability, end‑to‑end encryption on public networks and helps protect traffic from ISP or hotspot snooping.
