I regret two things, first moving to Vodafone secondly, getting a smartphone (HTC Desire HD) that is only supported on the 2100 network. I work out of home and rely on technology for business. I'm very upset & disappointed with the quality and reliability of the Vodafone tower close to where I live in Cherrybrook/Pennant Hills area. The phone keeps dropping off the network, sometimes 3 or 4 times within 10min and when I do manage to get connected I'm lucky if I get 0.03mbps data speeds. When comparing reliability and data speeds with neighbours on Telstra or even Optus it is simply embarrassing. Telstra was so much faster on their NextG & even more so on 4G. Consequentially I'm seriously considering adopting Telstra for all my future business telecommunication needs as my business expands. That includes the pending purchase of mobile internet for iPAD/Tablets/laptops and additional mobile phones. When I called Vodafone about my problem they just simply told be to set the phone to GSM 2G only which made no difference than was told I have faulty phone. HTC were fantastic but diplomatic helping me to resolve issue the but alias the phone was fine. Vodafone attitude was simply "You are getting a further discount so put up with it". To be fair to Vodafone, I don't have a problem when visiting places like Crows Nest, data speeds on the 2100 network is very good indeed and so is the reliability but I don't live or operate in Crows Nest. One short term solution I guess is for Vodafone to provide, swap or offer an HTC phone that supports both HSDPA 850 & 2100 until my contract is up for renewal October 2012 then I can re-evaluate the relationship to see if there is any significant improvements with the network and or customer service.
