JamboSim eSIM Data Plans for United Kingdom

JamboSim does not provide a truly unlimited data eSIM for the United Kingdom. All plans titled “Unlimited” give 3GB of high‑speed data per day; once that limit is reached the connection slows to 1000kbps. Travelers who need more data without speed throttling can choose fixed‑data plans. For example, a 20GB plan for 30 days costs $8.99, a 50GB plan for 30 days is $75.99, a 50GB plan for 90 days is $101.99, and a 100GB plan for 180 days is $195.99. These options offer large data allowances that may be more cost‑effective for heavy data users.

JamboSim sells United Kingdom eSIMs that include a local phone number with the dialing code +44 and allow outbound calls and outbound text messages. The plans are priced between $3.99 and $29.99, with validity periods ranging from 3 days to 30 days. The available data caps vary from 1GB to 50GB, and all plans support tethering and 5G connectivity. Users who need inbound voice or text services should check directly with JamboSim for the most current options.

JamboSim provides 26 single‑country data plans that are available specifically for the United Kingdom and 47 multi‑country plans that include the United Kingdom among the covered destinations. The single‑country options range in price from $1.99 to $185.99 and offer data caps between 200 MB and 100 GB, with a validity period varying from three to 365 days. The multi‑country plans share the same overall price and data‑cap ranges, but give the flexibility to use the data across multiple connected regions. Fixed‑data‑cap plans allow a set amount of data per period, whereas daily‑cap plans charge a daily allowance that can reset each day; both types are available within the UK offerings.
