Just thought to share this information.
We visited Hong Kong 2 weeks ago and picked up the One2Free prepaid sim card - the price is no longer HKD $88, but now $100 (cash/credit card was fine, and they dont need your ID or anything).
The 1010 shop at the airport is now located on the arrivals floor (was on departure floor 2 years ago).
7 day unlimited internet is still $78 of your credit so you now have $22 to spend on local calls
As an aside - I bought 2 sim cards (for wife and myself). One nano sim sized for the iphone 6, which seemed to switch to 4G, and one micro sim sized card. I was able to use this in both my LG G3 and my unlocked Telstra 4G wifi device (ZTE MF91).
The personal hotspot worked fine for both phones (although I had to setup the APN for the LG)
When I came back to Aus, I found it does roaming on Telstra
Haven't figured out what to test the remaining credits on yet.
Speeds were good whilst in HK - I got my Lollipop update whilst in HK, and I swear the 500mb? download came down faster than it would on my Optus cable internet here.
The hotel (Cosmopolitan) offered complimentary internet via a "Handy" device, that was 3G - unreliable and unbearably slow when it did work.
