SimSmash eSIM Data Plans for United Kingdom

No, SimSmash does not provide a truly unlimited data eSIM for the United Kingdom. The plans that carry “Unlimited” in their name are fixed‑data plans that allow a specified amount of high‑speed data each day; once the set amount is reached the speed is throttled.

Travelers who need a large data allowance can choose from SimSmash’s fixed data plans, such as the 50GB for 30 days plan priced at $20.49 USD or the 20GB for 30 days plan at $9.99 USD. These options give a set amount of high‑speed data for a definite period, which may be more cost‑effective for most users.

SimSmash does not provide United Kingdom eSIM plans that include a phone number or SMS capability. The provider offers only data‑only eSIMs for the United Kingdom. Travelers who need voice or text services can use popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should verify that these services are accessible in the United Kingdom before purchasing, as some destinations may block or restrict certain apps.

SimSmash offers 13 single‑country eSIM data plans for the United Kingdom and 24 multi‑country plans that include the UK in their coverage. Plans are available in a range of formats, from fixed data packages that provide a set amount of data for the full validity period to daily data‑cap packages that reset each day. Prices vary from about $0.69 to $67.99, and data caps span from 490 MB up to 50 GB, with some plans allowing tethering.
