yosim only offers data‑only eSIM plans for Andorra, and none of them provide a phone number or the ability to send or receive SMS messages. For travelers who need voice or messaging services, popular VoIP applications such as WhatsApp, Telegram, and iMessage can generally be used over the data connection. However, some destinations may block or restrict certain apps or VoIP services, so users should confirm that the applications they rely on are available in Andorra before purchasing a plan.
