Summary: I bought this Samsung unlocked phone for my trip to Italy. I also took my iPhone and paid $120.00 for two hundred minutes and $120.00 for a data plan from AT&T. I went through the minutes during the first week of my four week trip and decided to see if I could get a SIM card for my little Samsung. I hadn't trusted that it would work, so I paid in my opinion too much to use my iPhone in Italy.
Summary: I chose this phone because it holds two SIM cards which you can switch between without having to remove them. I wanted an inexpensive phone to use in France and the U.K. On vacation. I was able to purchase SIM cards in Paris and London very easily, and they worked great! Now I have a back up phone to use at home as well. I would definitely recommend this phone.
Summary: A spare phone to carry as a backup. Also will carry an iPhone 4S with international coverage but due to the high cost of calling plus roaming, I plan to use the Samsung for occasional calls back to USA and the iPhone for Wi Fi access. Samsung works fine in US with a UK sim card for USA and Europe (and Asia). Lightweight and the standby time seems very long, may not have to carry charger on a 10 day trip. Sound quality is adequate. The two SIM slot is handy.
