Simsima eSIM Data Plans for United Kingdom

Simsima does not provide a truly unlimited data eSIM for the United Kingdom. All plans listed for the UK carry a fixed data cap; for example, the plans named “Unlimited – 7, 10, or 30 days” give 3 GB per day, after which the speed is reduced to 1000 kbps. Travelers who want higher data volumes can choose from Simsima’s fixed‑data plans, such as the 50 GB 30‑day plan or the 20 GB 30‑day plan, which offer larger high‑speed allowances before any throttling occurs. These fixed plans may be more cost‑effective than the “Unlimited” options for users who need substantial data but are not extreme heavy users.

Simsima does not provide a United Kingdom eSIM that includes a phone number or SMS capability. Travelers can only purchase data‑only plans from this provider in the United Kingdom. If voice or texting is needed, it is typically handled through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection; however, users should verify that these services are not blocked or restricted in the United Kingdom before relying on them.

Simsima lists 12 single‑country data packages that include coverage for the United Kingdom and an additional 10 multi‑country packages that also extend to the UK. The available packages span a price range from about $1.50 to $84.83 and offer data caps from 100 MB up to 50 GB. The service provides both fixed‑data plans, which give a set amount of data for the entire validity period, and daily‑cap plans, which limit the amount of data that can be used each day, allowing customers to choose a schedule that best fits their travel habits.
