New versions fix bugs, optimize security, and improve your phone's performance.
- Clean and optimize internal memoryBefore you leave, delete useless photos, videos, screenshots, WhatsApp audios, and apps you don't need during your trip. This will free up space for new photos, videos, and useful apps, and reduce potential malfunctions. Use cleaning apps if necessary.
- Make a full backup of your data, photos, videos, contacts, and documents. Use cloud services like Google Drive, Google Photos, OneDrive, or Dropbox. Enable automatic backup only when you're connected to Wi-Fi to avoid data usage. This way, if you lose your phone, you can recover everything from any other device.

Optionally, create a specific folder on your phone and in Google Drive or similar where you centralize all your trip information. If you're traveling with someone, share the folder link so everyone can easily access it.
Manage your Internet connection abroad: roaming, local SIM, eSIM, and Wi-Fi
La mobile connectivity This is a critical aspect when traveling, especially if you're visiting foreign countries. You should know all the options to avoid exorbitant bills or being stranded:
- Roaming within the European UnionIn almost all European countries, roaming is included in your national plan. You can use your phone as you would at home (calls, text messages, data), but there are reasonable usage limits that you should check with your operator. Be aware of exclusions (some special territories or countries that are no longer included in the agreement, as may be the case outside the EU).
- Roaming outside the European UnionRates are often sky-high. Before traveling, check your carrier's exact policy: check prices, international plans, data limits, and choose a plan if they offer one. If you decide not to use roaming, disable it completely in your settings to avoid accidental charges.
- Local SIM cardThis is the most economical option if you're spending several days in a foreign country. Upon arrival, purchase a local prepaid SIM card (in stores, airports, or supermarkets). You'll need an unlocked phone. Activate it and you'll be able to enjoy national data and calls at local rates. Make sure to keep your regular SIM card or use a dual SIM card if your phone allows it.
- international eSIMSome recent Android phones allow you to install an eSIM (electronic card). You can purchase one online from providers such as Holafly, TravelSIM, or MiSimCard and activate it before landing. It's the fastest and most convenient solution, without having to change your physical card. Ideal for those who travel frequently or to several destinations in a short period of time. Check that your phone is compatible and follow the provider's instructions to install the eSIM by scanning the QR code.
- WiFi onlyIf you barely need a connection outside the hotel, you can skip mobile data and use Wi-Fi only in accommodations, cafes, airports, or shopping centers. Download maps, translators, and other entertainment beforehand so you can use them offline. Caution: Public Wi-Fi networks require extra security measures (VPN, avoiding access to sensitive information, etc.).
Professional adviceIf your phone allows dual SIM (or one physical SIM and one eSIM), set the foreign SIM for data only and keep yours for calls/SMS. This way, you can receive important calls and enjoy cheap local internet at the same time. Make sure you select the active SIM for each function (calls, messages, mobile data) in your settings.
