JamboSim eSIM Data Plans for United Kingdom

JamboSim does not provide a truly unlimited data eSIM plan for the United Kingdom; all of its plans list a fixed data cap, most commonly 3GB per day. The plans that carry the word “Unlimited” in their name still have a daily limit of 3GB, after which the speed is reduced to 1000kbps.

If a traveler prefers a larger, fixed data allowance, JamboSim offers examples such as a 100GB plan valid for 180 days or a 50GB plan valid for 30 days. These options give high‑speed data until the data cap is reached and may be more cost‑effective for heavy data users.

JamboSim does provide United Kingdom eSIM plans that include a phone number and SMS capability. These plans cover 1GB to 50GB of data and run for 3 days up to 30 days, with prices ranging from $2.99 to $31.99 USD. Each UK plan uses a local dialing code of +44 and offers outbound voice and outbound SMS services only; inbound calls or messages are not supported. JamboSim also offers Global+ plans that cover the United Kingdom but use a +1 dialing code; those plans provide the same outbound voice and SMS features. Users should verify the specific details and coverage directly with JamboSim before ordering.

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.
