There are three main phone card options.
- If you already have an unblocked mobile phone, you may consider simply buying a local SIM card upon arrival.
- Bring an international phone card with you. It should have a toll free access number suitable for Spain. Please note: 1-800 numbers DO NOT WORK when dialed from Spain, or anywhere in Europe for that matter. So make sure your card has a Spain-appropriate toll free access number.
- Buy a pre-paid international phone card once you arrive in Spain (very easy). They are available at local tobacco shops (which also sell postage stamps, by the way). It is possible to use this card for both local and international calls.
