I was traveling to UK from office and my assistant got me a local clay sim card for using there. And she told me that everything has been activated on the sim, data and plans to reduce my call charges to India. When I started using that sim card there, I realized that my data was really slow and somedays it woyld just not work. When I contacted my assistant complaining of the same, she directly connected me to the sales guy from Clay who seemed to be quite indifferent to the issues I was facing. No results on the data bit, somehow I managed the voice calls and then ultimately when I came back and returned to India, I got an ebill copy of rs 35k. All calls charged at an exorbitant price. None of my India calls were discounted despite having special packages activated. I was charged for data that didn’t work at all. Using a Clay Sim card was a really bad decision. These aren’t reliable at all
