Questions about travel data
How much data do I need for a week abroad?
1 to 3 GB is enough for maps, messaging, social media and browsing. If you stream video or make video calls every day, take 5 to 10 GB, or an unlimited plan.
Is 1 GB a day enough?
Yes for most travellers: 1 GB covers several hours of maps, social media and browsing. It goes fast with video: about 30 minutes of HD streaming.

Video: streaming, video calls and videos that autoplay in social apps. Maps, messaging and email use very little.
