SimSmash does not provide a truly unlimited data eSIM for the United Kingdom; the plans marketed with “Unlimited” in the name actually include a fixed high‑speed data allowance such as 490 MB, 1 GB, 5 GB or 10 GB for a single day before the speed is reduced. These daily “unlimited” plans do not offer high‑speed data without limits once the capped amount is reached, and thus are not considered unlimited.
If a higher data volume is needed, SimSmash offers fixed‑data plans. For example, a 50 GB plan for 30 days or 20 GB for 30 days are available, and a 50 GB plan for 180 days is also sold. These fixed plans can be more cost‑effective for travelers who expect to use a larger amount of data while visiting the United Kingdom.
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.
