Save data
Every eSIM plan either gives you a fixed amount of data (measured in gigabytes) or unlimited data at a flat daily rate. Picking the wrong size leads to one of two bad outcomes: you run out and scramble for a top-up, or you pay for capacity you never touch. The table above gives you the numbers to avoid both mistakes.
The biggest surprise for most travelers is how much video consumes. A single hour of HD YouTube uses more data than an entire day of maps and messaging. If you know you will stream, an unlimited plan from Holafly at $2.99/day is almost always cheaper than stacking per-GB bundles. If you stick to maps, messaging, and social photos, a 3-5 GB plan from Airalo or Nomad is the better value.
The table gives you averages, but your actual usage depends on which apps you use, how many hours a day you are on cellular data, and how long your trip lasts. Our data calculator combines all three into a single GB estimate and recommends the right plan size for your trip.
FAQ
A typical traveler uses 500 MB to 1 GB per day. Light users (maps and messaging only) stay under 300 MB. Moderate users (social media and photos) use 500-700 MB. Heavy users (streaming and video calls) use 1-3 GB per day.
Video streaming and video calls are the biggest data consumers. YouTube at HD quality uses 1.5 GB per hour. Netflix HD uses 3 GB per hour. A single one-hour Zoom call uses about 800 MB. Social media with autoplay video (TikTok, Instagram Reels) is the next heaviest category at 300-500 MB per hour.
Download offline maps, playlists, and translation packs on Wi-Fi before you leave. Set video apps to SD quality. Turn off autoplay video in social media apps. Use Wi-Fi at hotels and cafes for heavy tasks. These steps can cut your cellular usage by 50-70%.
For most travelers, yes. 5 GB covers a week of maps, messaging, social media, and light browsing with room to spare. If you plan to stream video or take daily video calls, you will need 10+ GB or an unlimited plan.
Get unlimited if you stream video daily, work remotely with video calls, or want zero data anxiety. Get a fixed plan (3-5 GB) if you mostly use maps, messaging, and social media. Fixed plans cost less when you do not need the extra capacity.
