yaySIM does not provide Bhutan eSIM plans that include a phone number or SMS capability; only data‑only eSIMs are available for travelers.
Because the plans lack a local phone number, users can rely on VoIP services such as WhatsApp, Telegram, or iMessage for voice and messaging over the data connection. However, some destinations may block or restrict specific apps or VoIP services, so travelers should confirm that the applications they need are accessible in Bhutan before purchasing.
