JamboSim eSIM Data Plans for Singapore

JamboSim’s plans that are named “Unlimited” for Singapore do not provide endless high‑speed data. Each of those plans supplies 3 GB per day and once the daily limit is reached the speed drops to 1000 kbps. Because of this throttling the plans are not truly unlimited.

Alternative options are available that give a fixed amount of data without a daily limit. For example, the eSIM Singapore 20 GB plan is valid for 30 days, and the JamboSim Asia 100 GB plan is available for 180 days. These fixed‑data plans can be more cost‑effective for users who need a larger total data allowance.

Yes, JamboSim offers Singapore eSIM plans that include a phone number and SMS capability. The plans range from 1GB for 7 days at $11.99 USD to 20GB for 365 days at $101.99 USD, with validity periods from 7 days to 365 days. Each plan provides a phone number with the dialing code +1, allowing outbound calls and outbound SMS but no inbound calls or messages. The eSIM covers Singapore and 171 additional countries. If you require inbound functionality or a local Singapore number, it is advisable to confirm the details directly with JamboSim.

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.
