Never use any Clay Sim Cards because these ppl have no business ethics at all. I happened to use their sim card for HongKong and i strictly instructed the sales rep to use my credit card details only as a security and not charge my card whatsoever. Firstly, their services were quite pathetic and then when they went ahead and charged the entire bill on my card without even sharing the itemised bill, totally proved that their services are horrible. !! Never recommending Clay Sim Cards to anyone in the near future.
