Data usage calculator
Choose a starting profile, adjust the activities you actually use, and get a practical estimate for your trip. Then choose a destination to see an available plan that fits.
Pick a profile
Quick shortcut: check your phone’s Screen Time (iPhone) or Digital Wellbeing (Android), then use the closest categories below. Add a little extra for photo backup, app updates, or limited Wi‑Fi.
Daily mobile-data activities
What is using the most data?
Your largest estimated data users are shown first. Video, video calls, downloads, and automatic photo backup can use data much faster than maps or messaging.
How much mobile data do you need?
Light travelers who mostly use maps, email, and messaging often need around 1–2 GB for a week. Streaming, video calls, social video, and photo uploads can push a trip beyond 10 GB. This calculator turns your own habits into an estimate so you can avoid buying too much—or running out mid-trip.
Useful context
Many people use roughly 5–15 GB per month, but that range changes dramatically with video quality and Wi‑Fi access. One GB can cover many hours of browsing or messaging, while HD video and video calling can consume about one GB per hour. Treat these figures as planning estimates: app settings, auto-play, downloads, cloud backups, and connection quality all matter.
