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 the ability to send or receive SMS. The only plans available for Singapore from ByteSIM are data‑only, so travelers cannot place or receive regular voice calls or SMS directly through the network. Travelers can still use VoIP services such as WhatsApp, Telegram, or iMessage over the data connection for voice and messaging. However, some destinations block or restrict certain VoIP applications, so it is advisable to confirm that the apps required for the trip are accessible in Singapore before purchasing a ByteSIM eSIM.

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.
