The most common mistake when buying an eSIM is guessing the data size โ you either overpay for unused traffic or run out before the trip ends. This calculator uses three factors: trip duration, usage intensity, and how many video calls you make. The output: a specific GB amount and the plan type that fits.
10-30 MB per hour of active use. A 2-week vacation with heavy navigation uses around 1.5-2 GB. Pre-downloading offline maps of cities cuts this by 5-10x.
Text is negligible, voice notes ~1 MB per minute, video calls 5-15 MB per minute. Standard vacation chats plus 2-3 voice notes per day fit within 200 MB for a week.
TikTok burns 300-500 MB per hour, Instagram Reels 200-400 MB per hour. An hour of scrolling per day for a week is already 2-3 GB on social alone.
YouTube HD uses 1.5 GB per hour, Netflix HD 2-3 GB per hour. If you plan to watch series during transit โ this is the biggest expense category.
300-500 MB per hour of standard quality call. Working remotely with 3-4 hours of calls daily? You need unlimited.
No fluff. 2-3 posts a week: eSIM news, insurance tips, payment hacks for travel abroad.
