Saily eSIM Data Plans for United Kingdom

Saily does not provide a truly unlimited high‑speed data eSIM for the United Kingdom. All of the plans listed for the UK carry a specific data allowance, such as 5 GB per day or a fixed total amount, and additional data beyond the limit is throttled to 1024 kbps. Because the name “UNLIMITED” in Saily’s plan titles refers only to the flexibility of the duration and not to an unrestricted data allowance, travelers seeking truly unlimited use will not find a corresponding option.

Travelers who need more data can choose from Saily’s fixed‑data plans. For example, the United Kingdom 10 GB 30‑day plan is priced at $19.99 USD, while the United Kingdom 20 GB 30‑day plan costs $31.99 USD. For longer trips, a 50 GB 90‑day plan is also available. These fixed‑data options are generally more cost‑effective for users who consume a large amount of data during their stay in the United Kingdom.

Saily does not offer United Kingdom eSIM plans that include a phone number or SMS capability. Only data‑only eSIMs are available, so to communicate while traveling you would need to use data‑based VoIP applications such as WhatsApp, Telegram, or iMessage, which work over the data connection.

Saily offers 11 single‑country plans and 16 multi‑country plans that cover the United Kingdom. These plans span a price range from free to about $95.99 and cover data caps between 500 MB and 50 GB. The provider offers two types of plans: fixed data‑cap plans (17 in total across all plans) and daily data‑cap plans (10 in total), allowing users to choose between a set amount of data for the validity period or a daily data limit.
