Running out is not a problem: you can add data to the same eSIM in seconds, with nothing to reinstall.
How we work it out
No black box. These are the exact figures, and you can check the arithmetic:
| Little | 100 MB/day |
| Normal | 300 MB/day |
| A lot | 700 MB/day |
| Sometimes | +250 MB/day |
| A lot | +900 MB/day |
| Will you share data with a laptop or tablet? | ×1,5 |
| Safety margin | +15% |
Estimates are per day and based on typical travel use — maps, messaging and some social media. Video is added, not multiplied, because the base already includes a little scrolling. The 15% margin absorbs a bad day, not a whole extra trip.
