Saily eSIM Data Plans for United Kingdom

Saily does not provide a true unlimited data eSIM for the United Kingdom. Its plans that carry the “UNLIMITED” name actually give a maximum of 5 GB per day and throttle speed to 1024 kbps once that daily cap is reached, so high‑speed data is not unlimited.

Travelers who need a larger data allowance can choose from fixed‑data plans instead. For example, a 20 GB plan valid for 30 days is priced at $30.99, and a 30 GB plan valid for 90 days costs $119.99. These high‑data plans are available for the United Kingdom and can be more cost‑effective for heavy data users.

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 makes 11 single‑country plans and 22 multi‑country plans available for travelers to the United Kingdom. The plans span a price range from $4.49 to $159.99 and data caps from 1 GB to 50 GB, with validity periods of 7 to 365 days. Some offers are fixed‑data plans that provide a set amount of data for the entire duration, while others use a daily data‑cap model that limits usage each day. This mix gives users the flexibility to choose between a flat data allowance or a daily‑based approach depending on their travel style.
