How much data do I need?

It depends on what you do on your phone more than on how long the trip is.

A rough guide, per week:

• Light: 1-3 GB. Maps, messaging, email, some browsing
• Medium: 3-7 GB. All of that plus social feeds, music and some video
• Heavy: 7 GB and up. Video calls, streaming, working off a hotspot

Video is what empties a plan. Streaming at high quality can use 1 GB in about 20 minutes, while maps and messaging all day usually stay in the hundreds of MB.

Sizes run 1, 3, 5, 10 and 20 GB, and there are unlimited ones. Data plans run 7 or 30 days, and unlimited runs from 5 days up to 30, depending on the destination.

Start small if you are unsure. You can buy more at any time and it lands on the same eSIM, so there is nothing to reinstall.
