Clay international sims are such a rip off --- I had decided to use clay sims for my Malaysia trip recently and seemed like a big mistake now. Of the 5 day trip, I could use their services only for 3 days and for the other 2 days I could either connect via wifi or not all. And now after 15 days of returning their SIM card I have received a bill of rs 9500 and surprising which indicates that I made calls in those 2 days when there was no cell reception at all.. I would like to warn everyone against clay sims for their loose service and cheating customers..
