That's surprising that they had a 36GB plan for HK$488 available that many years ago. If that's the case, I'm surprised that they don't have anything better on the new cards. I have an old China Unicom HK prepaid SIM that has very good voice rates while roaming (HK$0.45/minute) but the best it can do for data is HK$118/1GB/30 days.
