ByteSIM eSIM Data Plans for Singapore

ByteSIM does not provide a truly unlimited high‑speed data eSIM for Singapore. All plans that carry the “Unlimited” name in their title have a 1GB high‑speed data cap and, once that limit is reached, the speed is reduced to 10240 kbps.

Users who need more data can choose from ByteSIM’s fixed‑data options. For example, a 50GB eSIM is available for 3 days at $31.90 USD, for 5 days at $33.90 USD, or for 7 days at $35.90 USD. These larger‑volume plans offer a fixed high‑speed allocation without the throttling that applies to the “Unlimited” plans.

ByteSIM does not provide an eSIM for Singapore that includes a local phone number or SMS capability. All of their Singapore eSIM offerings are data‑only plans, meaning users do not receive an inbound or outbound voice line, nor are they able to send or receive standard SMS messages. Travelers looking to communicate can still use internet‑based messaging and calling apps such as WhatsApp, Telegram, and iMessage over the data connection, but will not have a traditional mobile number for conventional calls or texts.

ByteSIM currently offers 75 single coverage data plans for Singapore. These plans range in price from $2.90 to $65.90 and provide data allowances between 500MB and 50GB. ByteSIM also offers 35 plans with a daily data cap alongside 40 plans with a fixed data cap. Tethering is allowed on some plans, and reduced speeds may apply after a certain data usage threshold. No multi-country plans covering Singapore are currently available from this provider.
