Saily eSIM Data Plans for United Kingdom

Saily does not provide a truly unlimited data eSIM for the United Kingdom.
The plans that carry “UNLIMITED” in their name offer a 5 GB/day allowance; once that limit is reached the data speed is throttled to 1024 kbps, which effectively caps the plan after a few days of use.

If you need a larger high‑speed allocation, you can choose from Saily’s fixed data plans. For example, the United Kingdom 20 GB 30‑day plan provides 20 GB of full‑speed data for 30 days at a lower cost than the daily‑capped unlimited variants.

Saily does not provide an eSIM for the United Kingdom that includes a local phone number or SMS capability. The available offers from Saily to the United Kingdom are purely data‑only. Travelers can still use popular VoIP services such as WhatsApp, Telegram or iMessage over the data connection for voice calls and messaging, but there is no way to receive or send standard SMS or make conventional telephony calls with a UK number through Saily.

Saily lists 11 single‑country plans and 22 multi‑country plans that include the United Kingdom. The provider offers a range of pricing, from $4.49 up to $159.99, and data caps between 1 GB and 50 GB. Plans are split into daily data‑cap options—12 of them—and fixed‑data‑cap options—21 of them—letting users choose whether to pay for a set amount of data per day or for a lump sum of data that can be used over the plan’s validity period.
