JamboSim eSIM Data Plans for Singapore

JamboSim does not offer a truly unlimited data eSIM for Singapore. The plans that carry the word “Unlimited” provide 3GB of high‑speed data each day and, once that daily limit is reached, the speed is reduced to 1000kbps.

If a traveler prefers a fixed amount of high‑speed data, JamboSim offers several alternatives. For example, a 20GB plan valid for 30 days costs $10.99 USD and is available on 5G networks in Singapore, a 50GB plan for 90 days is priced at $39.99 USD, and a 100GB plan for 180 days is $71.99 USD. These fixed data plans can be more cost‑effective for users who anticipate high usage over the validity period.

JamboSim does not provide Singapore eSIMs that come with a phone number or SMS capability; the available plans are strictly data‑only. Travelers looking for voice and text services must rely on internet connections.

Over the data plan, VoIP apps such as WhatsApp, Telegram, and iMessage enable calls and messaging without a traditional phone number or SMS ability.

JamboSim offers 12 single‑country plans that are specifically available in Singapore and 33 multi‑country plans that include Singapore as part of their coverage.
Among the single‑country options, 12 plans have daily data caps, allowing users to control how much data they use each day. The multi‑country bundle plans consist of 33 fixed‑data‑cap packages that provide a set amount of data for the entire validity period.
Across both types of plans the prices range from about $1.99 to $94.99, while the data caps vary from 200 MB up to 100 GB, giving travelers flexibility to choose a plan that matches their usage needs.
