what i like that the the webchat facility has a lot more power than virgins. voda webchat was able to talk to me about billing where virgin wont and tell you to phone up.
i did get my pppoe username and password from them just incase i decide to use a different router. but my experience of the voda vox3 is very good so far so doubt i will be changing it.
Tbh the router is basic but fine. They happily gave me PPPOE details etc as well and told me to "do whatever you want" modem/router wise and that they would support any config. Thats decent tbh as normally if you aren't using the supplied kit then you get nothing.
