I got myself a new HSDPA card (Fastlink) and contract based on 3G coverage as per the MTN coverage map (http://www.mtn.co.za/default.aspx?pid=11789).
This map indicates that my area (Hennopspark, Centurion) is well covered with a 95% "signal available" rating where I stay. In reality I have zero 3G reception anywhere on my property (inside and outside). I even drove around with my laptop to test for 3G signal at verious spots in the area and where I got reception it was very weak (1 bar max for short periods).
I phoned the MTN data help desk (5551) but got nowhere with them. I complained on hellopeter.com and was told that their maps are accurate but that they will come back to me. Hasn't happened yet - and the map is obviously not accurate.
My 3G reception is perfect in Midrand (where I work) so there is nothing wrong with my card or settings.
Do these guys know what they're doing?! I'm not impressed.
BTW my company Vodacom HSDPA card works great at home.
