Bought to use in Argentina on trip. Worked fine though air time was expensive and difficult to add to phone as all prompts in Spanish and talked VERY fast. Now using with an AT&T "GO" phone sim card and costs about $0.10 a minute (rounds up to next minute so always more than 10 cents per minute per call. Has better reception and bigger screen than my tracfone and can be used anywhere as long as you have the right sim card
