so it is not very nice for clients...for genuine client! so are you using a mobile only for viva?
Some ladies do have a separate mobile for VS.
I do not because I have enough with 2 phones (1 work, 1 personal) I have one mobile for all my adverts, and link everything to my website that's sufficient for me.
If they do not tell me they've seen my website or AW, I ask them.
My VS has higher rates on it, this is to encourage visits to my website and probably puts some off which is fine. When they phone I always give my usual rates (ones on website, AW & VS).
Everyone no matter where they find my contact details gets the same information (unless of course they say they've read everything, and even then I will double check/confirm does and don'ts etc).
