Secure your holidays: 10 tips for a safe holiday - even with a smartphone

The holiday season is ongoing and no one would like to go anywhere without his smart- companions. So that you can enjoy a relaxing holiday, we have compiled for you a short collection of 10 important tips for the frustration-free handling of the digital helpers::

  1. Roam-like-Home: Since 2017, the EU regulation allows the use of foreign mobile networks on the same terms as in the home country. It applies in the 28 EU countries as well as Iceland, Liechtenstein and Norway. This does not include Switzerland and Monaco. However, there are other exceptions that you should note, as otherwise costs may arise:
    * By activating roaming, there might be also some other connections possible, which are not free of charge. The use of manual network selection can prevent this.
    * Regulation automatically applies only to private tariffs. There might be other conditions for business rates - Check your contract in advance!
    * Overseas territories, ships and aircraft using satellite-based communication are also excluded.
  2. WLAN WLAN: Pay attention to data security when using public WLAN hotspots in hotels and cafe bars. Use only encrypted services and ensure correct certificates - or use a VPN to stay safe.
  3. Attention, thieves: Newer high-end smartphones are sought-after objects. Especially in foreign environments you should take care of your devices: store them safely on the way and not put them on display (e.g. not necessarily in the rear trouser pocket or in an open handbag). Remember this also when someone offers to photograph you and your fellow travellers.
  4. Don't send invitation to unwanted guests: Do you want to post holiday greetings or info on social media? Limit the visibility of messages. Uninvited guests should not be informed too precisely about your absences, in order to avoid potential burglars.
  5. Plan B: The pin/fingerprint, theft protection or the localisation function on the smartphone should be activated (locate/find my device, trigger an alarm, delete data...). Test the function in advance to make sure that the procedure works. Keep the necessary access data (website, account data) extra - maybe you can also inform a trusted person at home who can offer you support in case of an emergency.
  6. Offline-Backup: Keep your most important account data (Google, Apple ID, Dropbox...) safe outside your phone so that you can still access them in case of loss.
  7. Data-Safe: Capture/scan important documents for the trip, put them in the cloud and synchronize them on your smartphone. At least you’ll always have a backup copy on your mobile phone or in the cloud with you.
  8. Offline-Navigation: Google Maps now supports offline maps by default. Once the destination view has been selected, the map section can be buffered directly on the mobile phone. This means that your smartphone can always support you during navigation, even if no data connection is currently possible.
  9. Emergency contacts: Set up the ICE contacts on the smartphone. ICE means "In case of emergency". The corresponding numbers stored on the mobile phone facilitate the notification of relatives and the identification of accident victims in an emergency.
  10. Public computer: Do you use one on holiday? Activate a 2-factor authentication for important services (Google, Facebook, Dropbox, eBay...) to get an additional SMS for the login procedure. This prevents the spying of passwords and identity theft. Avoid - if possible - the use of particularly sensitive services such as online banking on unknown systems

With these tips, nothing will stand in the way of your holiday pleasure. Just leave your smartphone in the hotel safe lock and enjoy the days off, the sunshine and the different view!


11. Do you have a charger with you? Immediately after the need for WLAN comes the battery status - Bring a travel adapter for the charger and a charger/USB cable on reserve. A power bank can also be useful in emergencies.
