Dont fall in the trap called Clay Sim Cards. As a student i can say, this was the worst telecom option that i ever used for UK. Being an addict to my BBM i considered their services cz i thought it wud be easy for dad to clear the bill in rs than the heavy pounds, and it turned out that these buggers robbed us in Indian rupees only. Slammed a bill of 23k for nothing at all!! 23k for just bbm!! What the hell !! My dad had to get this sorted and disconnected !! Total sham !!
