TailSim eSIM Data Plans for Singapore

TailSim does not provide a plan with a true unlimited high‑speed data allowance for Singapore. The offers that use “Unlimited” in their name actually grant 3 GB per day and then reduce the speed to 1000 kbps after that limit is reached.
If a traveler needs a larger constant data amount, TailSim offers fixed‑data plans such as 50 GB for 30 days or 20 GB for 30 days, which give high‑speed data for the full validity period without speed throttling.

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.
