TailSim eSIM Data Plans for Singapore

TailSim’s plans that include the word “Unlimited” are not truly unlimited. Those plans give 3 GB each day and after that limit is reached the speed is reduced to 1000 kbps. Therefore TailSim does not provide a high‑speed unlimited data eSIM for Singapore.

If unlimited data is desired, travelers can choose one of TailSim’s fixed data plans instead. For example, the 50 GB plan for 30 days costs $54.99 USD and the 20 GB plan for 30 days costs $26.99 USD, while a 10 GB plan for 30 days is $15.99 USD. These fixed‑data options keep the same speed throughout the validity period and can be more cost‑effective for most users, unless someone needs an truly unlimited data allowance.

TailSim currently does not offer Singapore eSIM plans that include a phone number or SMS capability. The available plans are data‑only and do not provide inbound or outbound voice or SMS services. Travelers who need messaging or calling can use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but they should confirm that these services are not blocked or restricted in Singapore before purchasing.

TailSim offers 14 single‑country data plans for Singapore, with no multi‑country options available. The plans vary between 1 GB and 50 GB of data and are priced from US $3.99 to US $82.50, with validity periods ranging from three to thirty days. Eight of the plans feature a daily data cap, meaning the allocated data is refreshed each day, while six plans provide a fixed data amount that is available for the entire validity span. This range offers travelers flexibility depending on how they prefer to consume data during their stay.
