RedEx eSIM does not provide any Bhutan eSIM with a phone number or SMS capability. The provider only offers data‑only plans for travelers visiting Bhutan, so users will not receive an incoming or outgoing voice line or the ability to send text messages over the local network.
Travelers who need to stay in touch can still use popular VoIP applications such as WhatsApp, Telegram, and iMessage over the data connection, but they should verify that these services are accessible in Bhutan before purchasing, as some destinations may block or restrict certain apps.
