FAQ
How many GB do I need for a trip abroad?
For maps, messaging, social media and web browsing, about 300MB per day is typical. That is roughly 2–3GB for 7 days; video and tethering multiply it several times. Use the calculator above to get an estimate from your trip length and usage.
How long does 3GB last?
About 7–10 days for maps, messaging and social media. Daily video can use it up in 1–2 days.
What can I do with 5GB?
Roughly 1–2 weeks of maps, social media, web and music. Video calls and streaming should be limited.
Is 10GB enough?
Usually enough for a 1–2 week trip with a little video. Daily long streaming or tethering will exceed it.
How much data does Google Maps use?
About 30MB per day even with navigation. Downloading offline maps reduces it further.
How much do Instagram and TikTok use?
About 150MB per day for browsing. Watching video continuously can reach several hundred MB to 1GB per hour.
How much data does YouTube use?
About 0.5–1GB per hour at standard quality, more in HD. One hour a day is roughly 5GB per week.
How much do LINE voice and video calls use?
Voice calls use about 30–60MB per hour; video calls about 300–600MB per hour.
How much does tethering use?
Laptops use far more than phones: about 1GB per day for email and documents, and 3GB or more with meetings and uploads.
How many GB do I need if my hotel has Wi-Fi?
Doing video and uploads over hotel Wi-Fi typically cuts mobile data by 20–30%. The calculator’s Wi-Fi setting accounts for this.
Should I choose an unlimited eSIM?
It becomes an option when your estimate exceeds 20GB. Note that high-speed allowances and conditions differ between unlimited plans, so check the plan details.
