Cellesim eSIM Data Plans for Singapore

Cellesim does not provide an unlimited data eSIM for Singapore.
The available options are fixed data plans, the highest of which is 50GB for 30 days, followed by 20GB, 10GB, 5GB and 3GB for the same 30‑day validity. These plans balance cost and data allowance for most travelers, though very heavy users might prefer a larger data bundle.

Cellesim does not offer any Singapore eSIM plans that include a local phone number or the ability to send or receive SMS messages. Travelers who purchase an eSIM from Cellesim for Singapore will receive a data‑only plan and will need to use VoIP applications such as WhatsApp, Telegram, or iMessage for voice calls and messaging. While these apps normally work over the data connection, some destinations may restrict or block access to specific services, so it is advisable to verify that the apps you intend to use are accessible in Singapore before making a purchase.

Cellesim offers 17 single‑country data plans for Singapore, with no multi‑country options available. The plans range in price from $1.92 to $137.25 and provide data caps between 1 GB and 50 GB, valid for 5 to 30 days. Among these, 10 plans feature a daily data cap that resets each day, while 7 plans offer a fixed data amount that does not reset daily.
