Good for first timers ----- I was going to Singapore for the first time in my life was quite frankly I was really confused about which International sim card to use. Obvioulsy I wanted afooradable options but also was looking for some good service. I reached the airport and i found the martix kiosk and the sales guys there explained everything in detail and helped me clear all my doubts… Must say it was a very wise choice as not only was it cheaper, but their services were par excelence. Recommending everyone to use it when they travel.
