Check Your Plan\u2019s Roaming Rules and Costs<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Roaming prices shift year to year as regulations change and providers update their agreements. Even if you travelled to the same destination last summer, your carrier\u2019s <a href=\"https:\/\/blog.lebara.co.uk\/fr\/a-guide-to-data-roaming\/\">itin\u00e9rance des donn\u00e9es<\/a> terms may have changed\u2014so verify everything a few days before your trip.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Log into your carrier\u2019s app or account portal (EE, O2, Three, AT&amp;T, Verizon, T-Mobile) and navigate to the <a href=\"https:\/\/blog.lebara.co.uk\/fr\/how-to-cut-the-cost-of-international-calls-on-a-mobile-phone\/\">internationale<\/a> roaming section for your specific destination country.<\/li>\n\n\n\n<li>For EU\/EEA trips, many UK and EU providers still offer \u201croam like at home\u201d with fair-use caps typically around 25-50 GB per month. Three UK, for example, applies a 12 GB fair use limit before throttling to slower speeds.<\/li>\n\n\n\n<li>Non-EU destinations often carry steeper costs. UK providers like Vodafone may charge \u00a32 per day for Europe-adjacent zones but \u00a36-\u00a37 daily for the USA or Asia.<\/li>\n\n\n\n<li>US carriers commonly offer \u201cInternational Day Pass\u201d options around $10-$15 per day, which typically include calls, texting, and a set <a href=\"https:\/\/blog.lebara.co.uk\/fr\/%ef%bf%bchow-much-data-is-optimal\/\">donn\u00e9es mobiles<\/a> allowance.<\/li>\n\n\n\n<li>Double check whether your plan covers calls and SMS or only data. Some roaming add-ons exclude voice calls entirely.<\/li>\n\n\n\n<li>Note the exact start date and end date of any add-on you purchase. Activating a 14-day roaming pass on 1 August when your flight departs 3 August wastes two days of coverage.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"2_Decide_How_Youll_Get_Data_Roaming_Local_SIM_or_eSIM\"><\/span>2. Decide How You\u2019ll Get Data: Roaming, Local SIM, or eSIM<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Before you leave your home country, determine your data strategy: keep your home SIM and roam, buy a local <a href=\"https:\/\/blog.lebara.co.uk\/fr\/a-beginners-guide-to-sim-cards\/\">Carte SIM<\/a> on arrival, or install a prepaid <a href=\"https:\/\/blog.lebara.co.uk\/fr\/%ef%bf%bca-guide-to-sim-card-sizes\/\">eSIM<\/a> in advance. Each approach has trade-offs in cost, convenience, and how much data you\u2019ll actually get.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Home-network roaming is the easiest option but often costs \u00a36-$10+ per day. It works well for short trips where you don\u2019t want to worry about setup.<\/li>\n\n\n\n<li>Buying a local sim card at the airport or city centre typically saves 50-80% compared to roaming (e.g., 10 GB for $15 in Thailand versus $100+ through your US carrier), but requires a SIM swap and sometimes passport registration.<\/li>\n\n\n\n<li>An eSIM is a built-in digital SIM supported on most phones from around 2018 onward\u2014iPhone XS and later, <a href=\"https:\/\/blog.lebara.co.uk\/fr\/8-reasons-to-buy-a-google-pixel-phone\/\">Google Pixel<\/a> 3 and later, and many <a href=\"https:\/\/blog.lebara.co.uk\/fr\/a-guide-to-the-best-budget-samsung-phones\/\">Samsung<\/a> Galaxy models. It lets you add a travel plan without physically swapping cards.<\/li>\n\n\n\n<li>Check eSIM compatibility on your device: iOS users go to Settings > Cellular > Add Cellular Plan; Android users check Settings > <a href=\"https:\/\/blog.lebara.co.uk\/fr\/how-to-find-out-what-network-youre-on\/\">R\u00e9seau<\/a> &amp; Internet > SIMs.<\/li>\n\n\n\n<li>Compare sample eSIM prices for your destination. Providers like Airalo offer 5 GB for \u20ac8 in Italy or 10 GB for $15 in Thailand\u2014often 70-90% cheaper than carrier roaming.<\/li>\n\n\n\n<li>Be aware that some destinations (Turkey, UAE, parts of the Middle East) require ID to purchase a local SIM and may limit foreign SIM use for stays over 30-90 days.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Configure_Your_Phones_Mobile_Data_and_Roaming_Settings\"><\/span>3.

On Android, navigate to Settings > Network &amp; Internet > Mobile Network > Roaming and disable it.<\/li>\n\n\n\n<li>If you only want Wi Fi access during your trip, enable airplane mode and then manually re-enable Wi Fi. This ensures your phone never connects to a cellular network abroad.<\/li>\n\n\n\n<li>Airplane mode alone isn\u2019t enough for long trips. Also disable background app refresh for heavy apps like cloud <a href=\"https:\/\/blog.lebara.co.uk\/fr\/say-goodbye-to-storage-woes-simple-steps-to-free-up-phone-space\/\">stockage<\/a>, social media, and email sync to prevent them from consuming your phone\u2019s data allowance without your knowledge.<\/li>\n\n\n\n<li>Reset your mobile data statistics the day you depart (iOS: Settings > Cellular > Reset Statistics; Android: Settings > Data Usage > Billing Cycle > Reset). This lets you track exactly how much data you use during your trip.<\/li>\n\n\n\n<li>Enable Data Saver or Low Data Mode to reduce background usage automatically. On iPhone, also disable Wi-Fi Assist (Settings > Cellular > scroll to the very bottom) to prevent your device from switching to mobile data when Wi Fi signal weakens.<\/li>\n\n\n\n<li>Consider this scenario: video streaming one HD film over roaming can easily exceed 3-4 GB. Without a plan, that\u2019s \u00a330-$50+ in unexpected charges for a single movie.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Secure_Your_Phone_and_Data_Before_Border_and_Airport_Checks\"><\/span>4.

US CBP conducted over 30,000 device searches in 2023, though this represents a tiny fraction of all travellers.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enable a strong screen lock before your departure date: use a 6-digit PIN minimum or a complex alphanumeric password alongside biometric unlock.<\/li>\n\n\n\n<li>Turn on Find My (iPhone) or Find My Device (Android) and verify it shows the correct location by checking from a laptop or computer before you travel.<\/li>\n\n\n\n<li>Activate remote-wipe features so that if your phone is lost or <a href=\"https:\/\/blog.lebara.co.uk\/fr\/what-to-do-if-your-phone-is-stolen\/\">vol\u00e9<\/a> in a foreign country, you can erase all data stored on it from your account dashboard.<\/li>\n\n\n\n<li>For higher-risk travellers (journalists, activists, lawyers), consider traveling with a \u201cclean\u201d device containing minimal data. Complete cloud backups before crossing any border where searches concern you\u2014some agencies can retain data for years.<\/li>\n\n\n\n<li>Update your <a href=\"https:\/\/blog.lebara.co.uk\/fr\/why-keeping-your-smartphones-operating-system-up-to-date-is-essential\/\">syst\u00e8me d'exploitation<\/a> and apps a few days before travel (e.g., on 5 April 2026 for an 8 April flight) to get the latest security patches without downloading large updates over roaming.<\/li>\n\n\n\n<li>Turn off lock-screen notifications for sensitive apps (banking, email, messaging) to reduce what a border agent can see during a basic inspection without unlocking your device.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"5_Back_Up_and_Free_Up_Space_for_New_Photos_and_Apps\"><\/span>5.

A 2023 Samsung study found travellers average 5,000 photos per two-week trip\u2014that\u2019s a lot of precious photos to protect.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Run a full backup over home Wi Fi the night before departure. Use iCloud, Google Drive, or your manufacturer\u2019s backup service to save everything to cloud storage or an external hard drive.<\/li>\n\n\n\n<li>Verify that important items\u2014photos from 2020-2025, <a href=\"https:\/\/blog.lebara.co.uk\/fr\/how-to-keep-phone-contacts-safe\/\">contacts<\/a>, notes, authenticator codes\u2014are safely stored. Check your backup date and confirm files are accessible from another device.<\/li>\n\n\n\n<li>Free space by deleting unused apps, clearing large downloads (old Netflix episodes, offline maps from past trips), and removing big videos. Aim for at least 10-20 GB free for a two-week holiday.<\/li>\n\n\n\n<li>Consider setting your <a href=\"https:\/\/blog.lebara.co.uk\/fr\/are-phone-cameras-better-than-traditional-dslr-cameras\/\">cam\u00e9ra<\/a> to a more efficient format like HEIF\/HEVC (iOS: Settings > Camera > Formats > High Efficiency), which produces files roughly 50% smaller than JPEG\/H.264 with minimal quality loss.<\/li>\n\n\n\n<li>After cleanup, confirm that critical apps (banking, 2FA authenticators, airline apps) still work and are logged in. You don\u2019t want to discover access issues while traveling internationally.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"6_Install_and_Prepare_Essential_Travel_Apps_and_Offline_Content\"><\/span>6.

Download music via Spotify, grab Netflix or Prime episodes, and save podcasts for long flights. Standard quality downloads use about 150 MB per hour versus 7 GB for 4K.<\/li>\n\n\n\n<li>Adjust streaming app settings to \u201cdownload only on Wi-Fi\u201d and \u201cstandard quality\u201d to save both data and storage space during your trip.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"7_Sort_Out_Charging_Adapters_and_Power_Management\"><\/span>7.

The voltage range should be printed directly on the adapter.<\/li>\n\n\n\n<li>Identify the plug type at your destination: Type C\/F for much of Europe, Type G for the UK, Type A\/B for the US and Japan, Type I for Australia and China.
