## What "unlimited" means here

Most unlimited plans give a fixed amount of fast data every day, then slow down until midnight. Enough for maps, messages and social media all day; not for video calls once the fast data is gone. See [how the daily limit works](https://findbestesim.com/blog/unlimited-esim-daily-limit-explained).

If you use less than about 1 GB a day, a plan with a fixed amount of data is usually cheaper: the [United Kingdom page](https://findbestesim.com/united-kingdom) shows both for your number of days.

## How to buy it

1. Open the [GigSky plan for United Kingdom](https://findbestesim.com/go/gb/gigsky-170205-7d-gb): GigSky's page opens on that plan.
2. Pay there. The eSIM arrives by email and in the provider's app, with a QR code.
3. Install it before you leave, while you still have Wi-Fi. On the plan's page, check when it starts counting days.

Prices change: we read them every day. The [United Kingdom page](https://findbestesim.com/united-kingdom) recomputes the answer for any number of days and any daily use.
