This clay telecom is highly recommended. I had used it on my last trip to Singapore. The coverage was good. Though I had some issue to setup data but once I get touch with their customer care team, they resolved it within 3 hours. I know there could be some issues in service industry but the way they resolved my issue it was amazing. I had just posted them on their fb page and got their response. This is called customer support. I am highly satisfied with their service.
