I purchased a prepaid SIM card with 3-day broadband service at M1 counter in Changi Airport. Unlike normal mobile phones like Nokia, iPhone didn't receive an APN or other network setting information needed for internet access. The M1 counter lady said I needed to bring the iPhone to the M1 shop at Paragon and have it installed settings there.
I asked the MRT station staff where I could get to Paragon and she answered I should go to Orchard station, so I took MRT train to Orchard.
M1 shop was on the B1 level. When I waited in line in front of the shop, a shop girl came to me and asked what she could help me. I told her I wanted to activated internet service for my iPhone. Then she led me to the front of counters in charge of activation or other services and gave me a paper printed a queue number to let me wait until the number was called. Tens of minutes later I was called by a counter girl. The activation took a little more time because my iPhone hadn't been purchased at M1 shop but in Hong Kong. Anyway the activation was successful and I could have access to the internet with my iPhone.
After activation I went to Little India.
There were plenty of Indian restaurants as well. The below is one of the local restaurants. People were eating foods put on a banana leaf by hand, like people in India do.
Because Singapore is very close to the Equator and today was almost autumnal equinox, the Sun passes the top of the sky. This video is when the Sun was on the top at solar noon. Vertical sunshine can never be experienced in Japan.
