Both my wife and I are fiscal residents in Valencia and are registered under the Spanish NHS and have SIP cards (Sistema de Informacion Poblacional). Under the system we can only get prescriptions issued for a month in advance. My question is if we were to spend 2/3 months in Tenerife would our SIP cards be accepted at a Centro de Salud or would we have to register as temporary residents (desplazados) to get the equivalent Canarian health card?
