About data usage

Different activities consume varying amounts of mobile data. Light browsing and messaging use minimal data, while streaming videos in HD can quickly use 1-3GB per hour.

Data-saving tips

Download maps and music for offline use, reduce video quality in streaming apps, and disable auto-play features to make your data last longer while traveling.

All our eSIMs can be topped up if you need more data during your trip. Simply log into your account and add more data to your existing eSIM in minutes.

Automatic app updates: apps downloading new versions (50MB-500MB per update)
System updates: phone firmware updates (500MB-4GB)
Cloud backups: photos and videos uploading automatically
Background app refresh: apps updating content in the background
Email sync: constant checking for new emails with attachments
