How accurate is the estimate?
It uses typical consumption rates for each activity and adds 20% headroom. Real use varies with video quality and how often apps refresh, so treat it as a solid starting point rather than a promise.
What uses the most data?
Video by a distance: around 900 MB per hour of streaming, and about 450 MB per hour of video calling. Maps and messaging are tiny by comparison — under 10 MB per hour.
What if I run out mid-trip?
Top up the same eSIM from your account in a couple of taps — no new QR code needed. We also email you before your data runs low.
Should I buy extra data just in case?
Not necessarily. Buying a smaller plan and topping up if needed usually costs about the same, and you avoid paying for data you never use.
Travel data calculator by Roamledge
Estimating mobile data for a trip is tricky: stream one film and you use more than a fortnight of maps and messages. This calculator turns your travel habits into a realistic gigabyte figure so you buy the right eSIM plan the first time.

The estimate is built from typical hourly consumption: about 8 MB for navigation, 6 MB for messaging and email, 160 MB for social feeds, 250 MB for photo backup, 70 MB for music, 450 MB for video calls and 900 MB for video streaming. We multiply by the hours you expect to use each day, then add 20% headroom for background updates.
If your plans change, you are never stuck: top up the same eSIM from your Roamledge account, and we will warn you by email before the data runs out.
