I had a great experience with Clay telecom services. Initially I had faced a small issue that my sim was not working once I landed to my destination Australia. But after reading all the brochure provided along with the Sim card, I could easily rectify the problem myself. After switching the Internet Mode to 4G, I had an awesome experience of High speed internet connectivity. During my trip only, I got a feedback call from the customer support team which was quite unexpected by any Indian company. Thanks to Clay for their services. I would strongly recommend to use clay services.
After reading the below comments I thought of writing my experience with Clay services. One should read the brochure properly before using any international SIM card. 90% of the problems would be solved if any. I had taken a Data and Voice plan for my trip to Australia.
