I cannot even begin to talk about my experience using clay sim cards. I took the sim card for UK thinking it would make my life simpler not realising when i would see my bill i would be in for a heart attack. 25k for 7 days !!! 10 pounds plan with promised 500 free minutes call to India which was all charged in my bill. Not only that my duration mentioned in the bill was also extended and charged my cc for someone else’ bill. I had to file an official complaint before these frauds actually took my matter seriously. !!
