Wireless broadband for Vista Komanwel?

As you know Nasioncom has stopped broadband service in Vista Komanwel, therefore to have 99% broadband uptime in Vista Komanwel, you need another broadband provider. A few days ago, a salesperson from Maxis told me Maxis wireless broadband is available in Vista Komanwel unofficially. So, if you have wireless broadband account from Maxis or Celcom, let us know which wireless broadband provider can be used in which area(s) in Vista Komanwel, e.g. block C2, 8th floor for Maxis. You can leave the information in the comment section. Thanks.
