ByteSIM does not offer any Seychelles eSIM plan that includes a local phone number or SMS capability. Travelers can only purchase dataโonly eSIMs from ByteSIM for use in Seychelles.
Because no voice or SMS service is provided, users can still make calls and send messages through VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, but some destinations may restrict access to these services, so it is advisable to confirm that the apps you rely on are available in Seychelles before buying the eSIM.
