Wi-Fi Abroad: Important Function to Disable

Travelers going abroad should be aware of the risks associated with roaming charges. Despite the abolition of many roaming fees within the EU, certain convenience features related to Wi-Fi can incur unexpected costs. One such feature is the automatic connection to open Wi-Fi networks, which is enabled by default on many smartphones. This automatic Wi-Fi connection can lead users to inadvertently join insecure networks. These networks are often inadequately protected and can be exploited by cybercriminals to capture personal data.

Experts therefore advise disabling this feature before departure to ensure the security of personal data. To disable the automatic connection, users need to look for the Wi-Fi option in their device settings. There, the “Auto-connect” or “Public Wi-Fi networks” feature can be turned off. This prevents the device from connecting to an unknown network without consent. Additionally, travelers should ensure that they only connect to trusted networks.

Public Wi-Fi networks in cafes, hotels, or airports are often not secure. Using a virtual private network (VPN) can provide an additional layer of security by encrypting the internet connection and protecting privacy. Another important point is to check the data roaming settings. Although roaming fees have largely been abolished in the EU, users outside the EU can still incur high costs. It is advisable to review the roaming options in the mobile contract and disable them if necessary to avoid unexpected charges.

Using offline maps and apps can also help save data volume. Many map apps offer the option to download maps for specific regions, allowing users to navigate without an internet connection. This reduces the need to connect to public Wi-Fi networks. Deutsche Telekom has found in a survey that 45% of travelers abroad do not take precautions regarding their Wi-Fi usage. This can lead to significant financial burdens, especially if users unknowingly consume large amounts of data while roaming.

To enhance security abroad, travelers should also regularly update their software and apps. Security updates often close known vulnerabilities that could be exploited by attackers. An up-to-date operating system and current apps provide better protection against cyberattacks. Using two-factor authentication for important accounts can also help increase security. This method requires an additional confirmation code, often sent via SMS or through an authentication app, in addition to the password.

This makes it more difficult for attackers to access personal data, even if they know the password. The Federal Network Agency has pointed out that travelers should inform themselves about the roaming conditions of their mobile provider before departure. Many providers offer special travel packages that allow for cost-effective data usage abroad. These packages can be a sensible alternative to regular roaming fees. Proper preparation before a trip can help avoid unexpected costs and ensure the security of personal data. Users should be aware that the responsibility for the security of their data ultimately lies with them. Deutsche Telekom recommends checking and adjusting device settings before traveling abroad to avoid unwanted costs.
