yaySIM does not provide an eSIM for Spain that includes a phone number or SMS capability. Travelers who purchase a yaySIM Spain plan will receive a data‑only profile. For voice and text communication they can rely on VoIP applications such as WhatsApp, Telegram, or iMessage that operate over the data connection; however, some destinations may restrict or block certain services, so it is advisable to confirm the availability of the apps you rely on while in Spain before buying a plan.
