What a 10GB eSIM actually covers
10GB translated into hours per activity, the trip lengths it fits, and what to watch before choosing this size.
Quick answer
- 10GB suits roughly a 7 to 14 day trip at moderate use.
- Every figure is computed from the per-hour rates we publish, not measured on your device.
What 10GB 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 10GB into approximate hours per activity.
| Activity | Roughly covers (10GB) |
|---|---|
| Video at 1080p | 5.7 hrs |
| Video at 720p | 11.4 hrs |
| Video calls | 10.2 hrs |
| Scrolling social feeds | 22.8 hrs |
| Streaming music | 113.8 hrs |
| Turn-by-turn maps | 409.6 hrs |
Figures come from the per-hour rates used in our calculators, not from measurements on your own device.
Which trip lengths this size fits
Broadly, 10GB suits a 7 to 14 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.
- One to two weeks, or occasional hotspot use for a laptop
- Daily hotspot use pushes you toward 20GB or a daily plan
- When unsure, add about 15 percent: app updates and photo backup are the two things people forget to count
Every figure here is computed from the consumption rates we publish, not from field tests, and none of it shifts with what we earn on a plan.
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
FAQ
What if 10GB runs out before I fly home?+
Top up the same profile if the plan supports it, or buy a second profile and install it alongside the first. Neither requires removing your home SIM. Topping up usually costs more per gigabyte than buying the right size up front.
Does leftover data from 10GB carry over?+
No. Anything unused expires with the plan, because validity is tied to the date, not the remaining balance. That is why buying far more than you need is not automatically the safer choice.
Can I hotspot a laptop on 10GB?+
Yes when the plan says sharing is allowed, but a laptop consumes far faster than a phone: full desktop pages and background updates add up. If you plan to share every day, look one size up.
