Not long ago I went to Spain (Villa Moraira) where I manage to get calls much cheaper than most people. A GSM phone that is also unlocked is what you need. What this means is that you can use any type of SIM card you want and still access the local phone network. I took my camera phone and got some Spanish villa images as well.
Once you have determined if your phone uses GSM then you will have a few options to choose from. An international SIM card is one very good option which you can get from STA. You will get a whole $10 of international call credit with your $9 SIM card. What is great about this SIM is that all your friends back home can call you free of charge for 30 minutes. This is great to save people having to pay massive fees to get hold of you in an emergency. You can have this card delivered to your house before you leave, which means you don’t even have the hassle of having to find a calling card when you are away.
With a Happy Movil offer an easy to use SIM card for 10 euros. 5.8 cents per minute is the typical call cost and you start with 5 euros on your card. That is enough for 71 minutes of continuous call time, which should last you for a weeks holiday.
Finally using a Vodafone SIM and calling card you are able to get a full hours worth of calls for just 28c. 1.2c a minute is the usual cost of a call back to where you live, which when compare to the others is a good price. In addition to this Vodafone is just one of four networks operating in Spain and will give you great network coverage throughout the country. This will stop any leisure holidays turning into walking holidays.
