At an illustrative 1 GB a day, budget 3 GB for three days, 5 GB for five days or 7 GB for seven days, before adding a separately chosen buffer.<\/strong> That daily figure is an assumption, not a measured average, a minimum or a guarantee that you will have enough. Our recommendation is to use your own comparable usage to choose a daily budget, then multiply it by your trip length.<\/p>\n

Research checked: 31 October 2026. This research-only guide explains a planning method; it does not assess destination coverage, package availability or speeds.<\/em><\/p>\n

Start with a simple calculation<\/h2>\n

Before choosing an allowance, inspect a recent usage period that resembles how you expect to use your phone abroad. Use that as a starting point, then adjust your daily assumption for your planned activities. Treat a quiet sightseeing trip and a trip involving substantial downloads or backups as different planning scenarios, rather than expecting one allowance to suit both.<\/p>\n

Choose your buffer separately. We recommend making it a deliberate extra amount for the activities or uncertainty you expect, rather than applying a universal percentage. Keep the base calculation and buffer distinct so you can see what you are buying and why. If your own usage suggests a different daily assumption, replace 1 GB in the calculation.<\/p>\n

Check usage on your phone<\/h2>\n

iPhone (iOS):<\/strong> open Settings \u2192 Cellular<\/strong> or Cellular Data<\/strong> to view mobile usage. Use this information to inform your estimate. Apple warns that exceeding an international plan\u2019s limits can exhaust the allowance or reduce speeds. See Apple\u2019s guidance on international roaming and data usage<\/a>. Consult your carrier about roaming availability and charges.<\/p>\n

Android:<\/strong> menus vary by manufacturer and software version. As a Pixel-specific example, open Settings \u2192 Network & internet \u2192 SIMs \u2192 App data usage<\/strong>. This shows usage for a selected period and by app. A data warning sends a notification; a configured data limit turns mobile data off. Follow Google\u2019s Pixel data-usage instructions<\/a> if they match your phone, rather than assuming every Android device has that route.<\/p>\n

Check expiry as well as the allowance<\/h2>\n

Our recommendation is to check both the total data and the validity period before buying. For example, Airalo\u2019s fixed-data package guidance says the allowance covers the whole validity period: it is not a fresh, equal allocation each day. Read the selected package\u2019s terms instead of treating the planning table as its daily entitlement.<\/p>\n

Airalo says validity can start at installation or when connecting to a supported network in the coverage area. Most of its packages use the network-connection trigger, but check the selected package\u2019s Validity Policy. See Airalo\u2019s explanation of data amounts and validity<\/a>. These are the terms described in Airalo\u2019s fixed-data guidance. Follow the validity policy shown for your own selected package.<\/p>\n

Review after the first travel day<\/h2>\n

Compare your actual usage with your daily assumption, then check the provider\u2019s remaining balance and expiry. Google notes that phone and carrier measurements can differ, so use the phone counter alongside the provider\u2019s figures. If you are using more than planned, reconsider downloads, backups or the allowance you need for the remaining days. Repeat the calculation with what you have learnt.<\/p>\n
