JamboSim eSIM Data Plans for Singapore

JamboSim does not provide a truly unlimited data eSIM for Singapore. All plans that carry “Unlimited” in the name actually supply a fixed allowance of high‑speed data, namely 3 GB per day, after which the speed is throttled to about 1 Mbps. Travelers who need very large amounts of data can choose fixed‑data plans such as the eSIM Singapore Unlimited/10 Days plan, which offers 3 GB high‑speed data each day for 10 days, or the eSIM JamboSim Asia 100 GB/180 Days plan, which gives 100 GB of high‑speed data for 180 days. These fixed‑data plans may be a more cost‑effective option unless a user requires truly unlimited data.

Yes. JamboSim sells Singapore‑covered eSIM plans that include a phone number and outbound SMS capability. The plans range from 1GB for 7 days priced at $11.99 USD to 20GB for 365 days at $105.99 USD. Each plan offers an international dialing code of +1, allowing users to make outbound calls; outbound SMS is also supported. Calls and SMS can be sent but not received, and callers can confirm any further details directly with JamboSim.

JamboSim provides 12 single‑country data plans for Singapore, covering data amounts from 200 MB up to 100 GB, priced between $1.99 and $105.99. In addition, there are 33 multi‑country plans that include Singapore on the coverage list; these also span the same data and price ranges. The plans are split into two types: 12 are daily data‑cap plans, offering a set amount of data each day, while 33 are fixed‑data‑cap plans where the data amount remains constant for the entire validity period. Both types support tethering and include a reduced speed option of 1 000 kbps.
