Smartphones simplify our daily lives, offering us instant access to information and communication at all times. When you’re abroad, your phone becomes a valuable ally for optimizing your travel experience and staying in touch with loved ones back home. To travel with peace of mind and remain connected in all circumstances, here are our best tips for making the most of your smartphone abroad.
Do: Disable data roaming
Before leaving the country, whether by plane, train, or boat, take the time to cut it off at the source: immediately disable data roaming and mobile data on your phone. The goal? To prevent your device from continuously trying to connect, which can unexpectedly inflate your phone bill.
But stay vigilant! Some applications, especially those that engage in automatic synchronization (Google, iCloud, Dropbox, etc.), can discreetly reactivate mobile data. So, carefully review your list of applications before departure, uninstall those that are not essential, or limit their data access.
While you’re at it, reset your data counters to zero. This way, during your trip, you can monitor your consumption in real time: any data-hungry application will immediately stand out, alerting you to unwanted usage.
Don’t: Rely on airplane mode
Airplane mode, contrary to what you might think, does not disable data roaming or mobile data! While airplane mode does cut all radio connections (cellular, Bluetooth, Wi-Fi), applications that don’t require a constant network connection will continue to use your data.
The best defense? Directly disable data roaming, or even better, opt for a prepaid plan tailored to your destination. This way, you’ll avoid any financial mishaps related to your mobile usage.
Do: Upgrade your phone’s security
When traveling, your smartphone is the item most likely to be lost or stolen. Statistics prove it: it’s the number one portable device for disappearances during trips. Before you fly, take the time to strengthen its security:
- Set up and test multi-factor authentication methods accessible even without calls or SMS.
- Install a VPN to protect your data when connecting to public Wi-Fi networks abroad.
- Opt for a password manager to secure all your sensitive information.
- Ensure your security patches and updates are performed before departure.
- Configure a geolocation application to easily find your phone if it gets lost.
Don’t: Neglect a protective case
The security of your data is essential, but the security of your device is just as important. A sturdy protective case and a screen protector, especially if you’re the adventurous type, will save you a lot of hassle.
When climbing a steep trail or running after a train, a simple fall can be enough to crack the screen or damage a vital component. By properly equipping your phone, you’ll save yourself stress and unpleasant surprises during your getaway.
Do: Opt for a prepaid data plan (eSIM)

Stop wasting your time changing SIM cards or desperately searching for Wi-Fi. Today, you can access ultra-convenient and affordable data plans thanks to eSIMs. Platforms like Vostra make everything simple: a quick download, activation in a few clicks, and you’re ready to browse online from practically anywhere!
Whether it’s for checking maps, booking a hotel, or finding a great local spot, having a stable connection transforms a complicated trip into a stress-free adventure.
If your smartphone dates from after 2018 and is not an entry-level model, it is likely eSIM compatible. Check the list of compatible devices and enjoy instant connectivity.
Don’t: Rely on Wi-Fi
Avoid relying on Wi-Fi, especially when traveling abroad. Although internet access is more widespread in developed countries and tourist areas, there’s no guarantee of connection stability, speed, or even availability.
Turning to a prepaid eSIM plan ensures a reliable connection, anywhere in the world. Download, activate, and recharge if needed: it’s that simple. This way, you’ll avoid unexpected disconnections and enjoy permanent access to everything you need online, without depending on a random hotspot.
Do: Back up and protect your data before departure
Before you hit the road, remember to keep a secure copy of your data in the cloud. This way, it will remain accessible and protected, even if lost or stolen during your travels. Also consider a factory reset to erase all your sensitive information. Two major reasons motivate this precaution:
- Border and customs controls: Border security agents, particularly in the United States or abroad, may be authorized to search your devices. In some countries like China, there are even reports of spyware being installed that can extract your SMS, personal data, and social media activity.
- Risky public Wi-Fi networks: Open Wi-Fi connections, for example in airports, are increasingly attracting cybercriminals, always on the lookout for sensitive data. Even with a VPN, you never know who is truly observing your traffic.
If you’re hesitant to reset your phone before you leave, make sure to do it as soon as you return. Consider your device potentially compromised after using dubious networks abroad and take the necessary steps to limit the risks.
Don’t: Trust public Wi-Fi

Do not leave automatic Wi-Fi connection enabled while traveling. Even without intentionally connecting to a network, your data can be exposed to theft. Be vigilant and disable this feature:
- On iPhone:
- Go to « Settings »
- Tap « Wi-Fi »
- Select « Ask to Join Networks » and activate this option
- On Android:
- Go to « Settings »
- Tap « Network & Internet »
- Tap « Wi-Fi »
- Go to « Wi-Fi Preferences »
- Disable « Connect to open networks »
A connected and secure trip is possible. With a few precautions, you can use your smartphone abroad with complete peace of mind. Whether it’s managing your mobile data, securing your device, or adopting a well-configured operating system, prepare the ground for connected, pleasant, and stress-free holidays.
