Never travel with any services provided by Clay SIm Cards. This company is a bunch of frauds and only there to mint money this way or that !! I took a clay sim card for Germany and got totally billed in Pounds??? Aghast !!! When i called up the sales guy, he said i can covert the money in Indian currency and pay the balance cz the security blocked on the card has been charged!! I mean when i was investigating the tariffs everyone said it will be billed in Indian currency!! Total FRAUDS !! And nobody there seems to offer any solution but keep on singing the song of clearing the bill !!
