GigSky does not provide a Spain eSIM plan that includes a phone number or SMS capability. All of GigSky’s Spain offerings are data‑only, so travelers relying on a local number for voice calls or text messages will need to use alternative methods.
While voice and messaging can typically be carried out with popular VoIP applications such as WhatsApp, Telegram, or iMessage over the data connection, this is not guaranteed. Some destinations may block or restrict the use of specific apps or VoIP services, so users should check that the services they require are accessible in Spain before purchasing a plan.
