Flysimo does not provide any unlimited data eSIM plans for the United Kingdom. The available options are fixed‑data plans, with the most generous offering being 50GB for 30 days at $29.06 USD and 50GB for 180 days at $47.86 USD. These plans allow tethering and are valid for the entire period, but they are capped at 50GB. Choosing a fixed data plan is typically more cost effective unless a traveler is an extremely heavy data user who would otherwise exceed the plan’s allowance.
Flysimo does not offer United Kingdom eSIM plans that include a phone number or SMS capability. The only options available from Flysimo for UK travel are data‑only eSIMs.
If local calling or texting is needed, users can rely on VoIP applications such as WhatsApp, Telegram, and iMessage, which work over the data connection and provide voice and messaging options without a phone number or SMS function.
Flysimo provides eight single‑country data plans that cover the United Kingdom alone and 36 multi‑country plans that include the UK. The available plans range in price from $2.59 to $153.30 and offer data caps between 1 GB and 50 GB, with validity periods that span from 7 days up to 365 days. Some of the plans support tethering, allowing the data to be shared across multiple devices.
