ZenSim eSIM Data Plans for United Kingdom

ZenSim does not provide a true unlimited high‑speed data eSIM for the United Kingdom. All plans that carry “Unlimited” in their name have a data cap of 3 GB per day; after that amount the speed is reduced.

Travelers who need larger data allowances can choose from ZenSim’s fixed‑data plans. For example, a 20 GB plan is available for 10 days at $26.00 USD or for 30 days at $29.00 USD, and a 10 GB plan is sold for 10 days at $18.00 USD. These fixed plans are often more cost‑effective than a daily‑limited “unlimited” package unless the user is a very heavy data consumer.

ZenSim does not offer United Kingdom eSIM plans that include a local phone number or SMS capability. All United Kingdom eSIM plans from ZenSim are data‑only and do not support inbound or outbound calls or text messaging. Travelers can still use VoIP and messaging apps such as WhatsApp, Telegram, or iMessage over the data connection.

ZenSim provides 8 single‑country plans and 8 multi‑country plans for the United Kingdom. Among the 16 plans available, 4 set a daily data cap while 12 offer a fixed data amount. Prices for these plans run from about $13.00 to $57.00, with data limits ranging from 3 GB up to 20 GB.
