aloSIM does not offer any eSIM plans for Taiwan that include a local phone number or SMS capability. The available plans are data‑only, so travelers will not receive an inbound or outbound voice line or SMS service from the provider.
Travelers who need to make calls or send messages can still use VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so it is advisable to confirm that the preferred applications are accessible in Taiwan before purchasing a plan.
