JamboSim eSIM Data Plans for United Kingdom

JamboSim does not provide a true unlimited data eSIM for the United Kingdom. All plans that carry “Unlimited” in their name offer a capped high‑speed allowance of 3 GB per day; once the daily limit is reached the speed is reduced to roughly 1 Mbps.

Customers looking for large amounts of data can choose from JamboSim’s fixed data plans, such as the 100 GB plan valid for 180 days or the 50 GB plan valid for 30 days, which give a set amount of high‑speed data over a specified period without being unlimited.

Yes, JamboSim sells several eSIM plans that include a phone number and the ability to send SMS while traveling in the United Kingdom. These plans use the United Kingdom dialing code +44, provide outbound voice calls and outbound SMS, and are available in a range of sizes from 1GB to 50GB and validity periods from 3 days up to 30 days.

The cheapest UK‑only plan is $2.99 USD for 1GB with a 3‑day validity, while the largest UK‑only plan is $31.99 USD for 50GB with a 30‑day validity. All of these plans offer a UK local number, outbound voice and outbound SMS capability. If you need a specific function such as inbound calls or SMS, it is advisable to verify the exact features directly with JamboSim.

JamboSim provides a range of data plans for travelers visiting the United Kingdom, including 25 single‑country plans that cover only the UK and 52 multi‑country plans that include the UK along with other destinations.
