How long 20 GB lasts
- Light use (0.4 GB per day, saved maps and messaging): about 41 days.
- Normal use (1 GB per day): about 16 days.
- Heavy use (3 GB per day, video and hotspot): about 5 days.
These are planning figures with a 20 percent buffer, the same ones the estimator on the home page uses. Real use depends on video quality, uploads and background apps.

Who it suits
Twenty gigabytes suits two weeks of mixed use or a trip where you share the connection with a laptop or another phone.
These plans last from 15 to 30 days. The validity and the data run out independently, so whichever ends first ends the plan.
Questions before you go
Is 20 GB enough for a trip to China?
It depends on the days and on how you use your phone. At normal use it covers about 16 days; at heavy use, about 5.
What happens when the data runs out?
Fixed plans stop until you top up or buy another. Check the provider’s top-up rules and keep an offline copy of your hotel address.
