There is actually a good survey, whether this operator or tariff blocks VoIP on this [http://www.xatakamovil.com/mercado/buscas-linea-movil-de-tarjeta-prepago-asi-son-las-tarifas-con-y-sin-internet Xatakamovil site. ] It's in Spanish, but easy to handle, because it's graphic. Just scroll down to the table and check, if 'Voz IP' is shown in green or red.

Actually very few operators block VoIP in Spain like on some Vodafone or Yoigo plans.
