My husband and I took a Clay International sim card for our recent trip to Malaysia thinking that we would be in touch with our family. What high hopes we had i must say !! I guess clay doesn’t understand the concept of connectivity !! We had to run to the phone booths to make calls to their super busy non existing customer execs who did not respond at all and our sims didn’t work throughout the span of 5 days. !! Terrible service quality !
