Disrupted!

I discovered today after lunch that my mobile phone's 4G wasn't working at all. At that point, I was going to a school. It was my first visit to the school and the taxi driver wasn't sure where the school is and his GPS wasn't working. I also couldn't check my Internet. :( We did finally find the school.
Not sure what happened with Singtel but the 4G mobile service only resumed in the late afternoon. :(
