MobiMatter eSIM Data Plans for United Kingdom

MobiMatter does not provide a true unlimited‑data eSIM for the United Kingdom. All available plans list a specific data cap, such as 20GB, 60GB, 120GB, or 28GB for the 3‑day bundle, and each has the same validity period and price set. Although some plans carry the word “Unlimited” in their name or feature a flag indicating an unlimited‑name designation, the actual data allowance remains capped; after the cap is reached, the plan does not offer continuous high‑speed data.

If a traveler prefers a fixed‑data option, MobiMatter offers several large‑data packages. For example, the UK 50 GB plan is valid for 30 days and the UK Premium 50 GB plan offers the same amount of data for a higher price, both with tethering allowed and coverage limited to the United Kingdom. A 120 GB EU plan is also available for 30 days, covering the UK and 31 other countries. Choosing one of these fixed‑data plans can be more cost effective for most users compared to attempting to use a "unlimited" title that still imposes a data cap.

MobiMatter does not offer United Kingdom eSIM plans that include a phone number or SMS capability. All of its United Kingdom offerings are data‑only eSIMs, so no traditional call or text service is provided. Customers can still use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection for voice calls and messaging.

MobiMatter offers 11 single‑country plans and 60 multi‑country plans that cover the United Kingdom. The available plans price between $3.49 and $74.99 and provide data caps ranging from 1 GB up to 120 GB. Some of the plans allow tethering, giving users the flexibility to share the connection with other devices.
