I strongly dislike Clay sim cards for a very simple reason, first they will chase you down to buy a sim card if at all yo decide to try their services, and then once the sale is closed they don’t believe in taking the ownership for anything, which is quite a *** off!! I took their post paid sim card for UK and suffered major signal issues and also with the data which just didn’t seem to work!! After 10 calls to the customer care and a equal number of mails, did they think of responding once saying they will fix it!! That fix never happened !!! Waiting to catch hold of the guy who will take the return delivery !!
