What the terms mean
Defined here so a price can be read correctly rather than guessed at.
- eSIM
- A SIM profile downloaded to a phone rather than inserted as a plastic card. A travel eSIM sells data in a destination without changing the phone's usual number.
- Throttled unlimited
- A plan whose data never runs out but which drops to a reduced speed after a stated full-speed allowance. It is not equivalent to an uncapped plan.
- Price per gigabyte
- The total plan price divided by its data allowance, used to compare capped plans of different sizes. It cannot be calculated for unlimited plans.
- Price per day
- The total plan price divided by its validity in days, used to compare unlimited plans, which have no per-gigabyte figure.
- KYC
- Identity verification some providers require before a plan can be activated, typically a passport scan.
- Top-up
- The ability to add more data to an eSIM already installed, rather than buying a new one.
