What a 1GB eSIM actually covers

What 1GB looks like in practice

Data is not consumed evenly. An hour of high-resolution video costs more than a full day of navigation. The table converts 1GB into approximate hours per activity.

Which trip lengths this size fits

Broadly, 1GB suits a 1 to 3 day trip at moderate use. If you use more than that, move up one size or switch to a daily plan that resets full-speed data each day.

• Very short trips, or a backup alongside hotel Wi-Fi
• Autoplaying video in a social feed can drain it in an afternoon
• When unsure, add about 15 percent: app updates and photo backup are the two things people forget to count

If this size does not match your trip

Wrong-size purchases usually rest on two assumptions: that hotel Wi-Fi will carry most of the load, and that uploading high-resolution photos is cheap. It is not — it costs about what watching video costs. When unsure, run our estimator against your own habits.

• Heavy use and no desire to think about quota: look at daily plans, or unlimited plans with a clearly stated fair-use policy
• Short trip but daily video calls: move up one size rather than topping up mid-trip
• Crossing borders: check regional plans first so you are not buying several profiles
