I bought the hk$48 for my dad as this contains no 3g function and is the cheapest.
It is better to ask them to activate the 7days unlimited internet access before you leave the counter, it will cost hk$78 and the remainder hk$10 can make around 100 minutes of phone calls. They have one hour and one day package but is just not worth it.
Hkd $78 for 7 days unlimited
Hkd$28 for 1 day unlimited
Hk$8 for 1 hour unlimitedGood if you are travelling in a group. Can always keep in touch.
Remember to bring extra phone for sg sim card, just a normal hp without 3g will do as whatsapp with singapore number can be used even when you insert the hk sim card.
top up voucher of denomination of hk$50 or hk$100 are available at the counter.
I don't think is necessary unless you intend to have lengthy chats.
go to the departure hall, 7th floor, lane G, IOIO shop. Arrival hall is 5th floor, so just take the lift or escalator up to the 7th floor.
just ask for the hk$88 sim and ask the person to activate the 7day unlimited internet access. If you don't activate this service, the 3G service is going to cost you a lot and the value will be gone.

Update: My friend bought Sim Card at hk$60 from chinamobile. Is much cheaper at less than hk$10 per day for unlimited and balance can be used for calls. However, the network is 2G, so it will be slightly slower. Will be good if you want to save money and don't mind the slower network.
Remember to grab some maps on the way out. Sometimes the hp seems to have problems loading and hard copy come in useful.
Is good to get a 3g sims as can use to do research on the various locations opening hours and how to reach the place. Use the map app available in most hp to plan the walking route. Hong kong MTR station has a lot of exits so it is very important to get out from the correct exit.
Can download some free and useful maps on your hp.
Find this very useful for trams or ding ding che travel. just download it.
