Yatelo sells only data‑only eSIM plans for Taiwan, so no plan includes a local phone number or the ability to send or receive SMS messages. Travelers who need a phone number for calls or text messages will need to use another provider that offers those services.
Because the eSIM plan gives full data access, you can still use VoIP applications such as WhatsApp, Telegram, or iMessage to make calls and send messages over the internet. Some destinations may restrict or block certain apps, so it is wise to check that the apps you rely on are available in Taiwan before purchasing a plan.
