The data card dongle of vodafone is useful for me and I am also user of this. I am from delhi(India). I baught this only for Rs. 1299 plan at last month and his speed service is very fast and low . I mean it depend on area. These data card dongle can be used on any type of service like- 2G and 3G. When I baught it then I unlocked this and now I can use every sim card with this and now I can use many types. But vodafone sim do not work properly.. but vodafone data card dongle is the best for 3g . useful service ...Thanks
