RedSim eSIM Data Plans for United Kingdom

RedSim does not provide a true unlimited data eSIM for the United Kingdom.
All of its UK offerings are fixed‑data plans that give a set amount of high‑speed data for a specified period, after which the speed is reduced to 1000 kbps. For example, the United Kingdom Unlimited 30 Days plan supplies 3 GB of high‑speed data each day for 30 days before throttling the remaining data to 1000 kbps, and the United Kingdom 50 GB 30 Days plan delivers a total of 50 GB of high‑speed data over a 30‑day validity, also with the same speed reduction once the daily limits are exceeded.

Using a fixed data plan such as the 50 GB 30 days or the 20 GB 30 days plans can be more cost‑effective for most travelers, unless a user foresees consuming significantly more data and prefers a truly unlimited option.

RedSim does not provide eSIM plans for the United Kingdom that include a phone number or SMS capability. Only data‑only eSIMs are available.

Travelers can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection for voice calls and messaging. However, availability of these services can vary by destination, and some apps may be blocked or restricted in the United Kingdom, so users should verify that the services they need will work before purchasing a plan.

RedSim provides 17 single‑country data plans and 34 multi‑country data plans that include coverage in the United Kingdom. The available plans span a price range from $1.18 to $75.60 and offer data caps between 1 GB and 50 GB. Some plans feature a daily data cap, limiting the amount of data that can be used each day, while others have a fixed data cap that allows the full data allowance to be used over the entire validity period. This range gives travelers flexibility in choosing a plan that matches their usage needs and budget.
