How we make this comparison
- We compare five plans: 1 GB for 7 days and 3, 5, 10 and 20 GB for 30 days. If a provider sells a different validity for that size, it says so in its cell.
- This page only exists for destinations where Glowi costs less than all three in at least 3 of the 5 plans. Where that isn’t true, we don’t publish it.
- A tie does not count as a win, and neither does a provider not selling a plan.
- We don’t compare speed or coverage because we have no measurements of our own.
