Do any of the internet service providers in HCM offer a Wimax option? This would be a special router that receives their internet signal via radio waves and would not need to be hooked up to either phone or cable. I've used this in the past in a different Asian country and it worked great.
I'm asking because I live in Sky Garden (PMH) and the internet (provided by SST) is horrible here. I've been told they are the only provider for the SG complex, so I'm looking for other options.
