I had used clay sim in Singapore for their long term plans and we actually got it disconnected within a few months. My dad was being charged bills amounting to 20k every month while mostly I was only receiving calls. The idea of getting a number before I got there, proved to a crazy expensive deal. I mean really bad service or options in comparison to offers available there. I mean I was paying some 10$ for a data pack that didn’t work most of the times. And endless times that I complained at their support centre even with emails and calls, it would be resolved for a few days and then back to the same story. Its more peaceful to hve their service discontinued than using it. I am actually more connected now at a much cheaper cost.
