Pathetic services and they do not honour contracts well-- my son was using a clay sim in London, specially the student plan. Their service was very bad and very expensive at the same time. I remember paying 26000 for a month against usage charges.. I finally decided to discontinue with their services, even cleared the rentals to get rid of their services. Even after all this, they send me monthly bills against the same number and infact did charge my care twice even after disconnecting the contract. Clay international sims are not at all trustworthy and it's a tedious task to get things right with them. Think twice before deciding to use their service.
