You can get a similar deal even cheaper from other service providers, I've checked it out recently.
Mobile 20+ Mbps download is about the best you can get anywhere on Lamma, I think. I've seen peaks of 50+Mbps but these are very rare.
No need for a USB toggle and additional SIM card, your mobile phone works usually fine as a Wifi hotspot for all your home devices. No extra costs besides your standard mobile/data plan and your standard PCCW broadband, about $500 in total expenses/month.
But it's the data caps that make this a not-perfect solution even though it works well and is sufficient data/month for anything but big up/downloads.
The search continues for Faster Broadband on Lamma continues and it doesn't look good. PCCW upgrading some of us to vDSL2 (new, expensive modem, but same copper phone wires and microwave link to HK Island), looks to be the only near-term option, maybe next year.
