Saily eSIM Data Plans for United Kingdom

Saily does not provide a truly unlimited data eSIM for the United Kingdom. All plans that carry the word “UNLIMITED” in their name are limited to 5GB per day; once that amount is used the connection throttles to a reduced speed of 1024kbps.

Travelers who need a higher data allowance without daily caps may choose fixed‑data plans. For example, a 20GB plan valid for 30 days costs $30.99 USD, while a 30GB plan for the same period is priced at $59.99 USD. These options offer a larger contiguous data pool and can be more cost‑effective for users who consume a lot of data.

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.
