Spain

In Spain, number portability among cell phone carriers is available since October 1, 2000, without any cost to the end user. The technical details for the process are regulated by the CMT (Comisión del Mercado de las Telecomunicaciones or Telecoms Market Commission) and all carriers are obliged to comply with their requirements. As of August 2007, cell number portability must complete in 5 business days (i.e. excluding weekends) from the moment the request is confirmed by the customer, with the actual switch occurring late at night to avoid missing any calls
