Eurobuzz worked fine for me. If all you want is to be able to make and receive phone calls this $30 gadget does it. calls are 79 cents per minute. That is high. But if you use it for those special times only...it is a cheap way to go. I spent six weeks in Spain this trip and my total phone charges were under $9.00.
Buying a country SIM is more than that and try getting a SIm to work using a foreign language. Or buy a calling card which is country specific...10 Euros ($14.00) and try making it work, when the connection giving directions is in a foreign language. Good grief how fast a=can those directions be made in French?
I have had the phone three years. Works fine. But it is not for socializing.
T-mobile sounds really nice, if you have that carrier.
