How long 3 GB lasts
- Light use (0.4 GB per day, saved maps and messaging): about 6 days.
- Normal use (1 GB per day): about 2 days.
- Heavy use (3 GB per day, video and hotspot): about 1 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
Three gigabytes work for a short city trip when you keep video off and update apps on hotel Wi-Fi before you go.
These plans last from 3 to 30 days. The validity and the data run out independently, so whichever ends first ends the plan.
Questions before you go
Is 3 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 2 days; at heavy use, about 1.
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.
