The worst that you will ever get to use ever --- I happened to use Clay Sim card for Malaysia and it was the worst services that i’ve ever used in a very long time. My sim card wasn’t working ever since i landed and the customer support were honestly support-less. They just kept on making a fool out of me by saying that they have raised the issue and resolving it but never really worked for me. Apparently the sim never worked but these guys were pretty quick to send me the bill worth 1200rs for something i don’t remember using.!
