Hey guys, Wanted to share my experience with all of this.
I just moved to a village house in S Lantau.
PCCW here is as bad as it gets. Its the only only option besides going mobile. No way was I going through that process.
So after a bunch of research(some here) and trial and error, I got a nice setup with 10mbps plus down and up, some days I see as much as 30.
So the three things you must have IMO are:
-- Smartone plan 6GB plus the extra for unlimited data (mostly) as mentioned before in this thread. Cost is almost 500hkd a month. I'm trying to find a neighbor who will go half with me if I share my connection. Pretty sure I will succeed at this as the #1 complaint I hear out here is PCCW.
--A good 4G router designed to recieve the frequencies of the provider (smartone is 1800 and 2600Mhz)
I ended up going with a B539-22 Huawei I bought off taobao. It is what the professionals recommended. I ended up paying around 100USD for it. You could probably find it somewhere in mongkok or SSP, but I didn't want the goose chase or marked up HK prices.
--Last is most important. A good antenna tuned for the frequencies smartone uses. I tried three different ones wasting money. All crap made in China. Finally for the last one, I bit the bullet and got the Poynting A-XPOL-006-10m antenna. It was about 135USD shipped from SZ (they have supplier there but it is made in europe). This is what I needed! I have 4 bars of signal and great solid internet now. PM me if you need the contact for this antenna. You pretty much have to just contact them directly and find the nearest supplier for shipment. Also, I wouldn't buy the antenna until you have tried the built in antennas on the router. They were surprisingly pretty good.
