I'm still trying to get my head around how these products work but as I understand it the 'physical' connection at the exchange is using the Opal/TalkTalk kit.
At some point on the surfwise packages the connection is handed on to the Obit network.
This is the network that provides your connection to 'the internet' so I guess this would have more impact on the quality of your service.
Can someone more technical help me out here please
At the end of the day you deal with Vivaciti and they are the ones who will act on your behalf with their suppliers.
I am with Zen at the moment so am perhaps a little spoilt.
I was with AAISP before moving to Vivaciti surfwise complete and have noticed minimal difference in the quality of my connection after having the 'file sharing add on' applied to my account.
