I want the black Sagemcom 3864v3 AC modem because the white Sagemcom 3864v3 OP modem has only one wi-fi band.
Optus told me I would have to pay extra for the black modem with two wi-fi bands if I want it but I think I should have had this one originally.
How much do I have to pay for this Black modem? Can I Keep the White single band modem as I have already paid for it?
Yes, you would keep the white modem as you originally paid for it. Sadly these devices aren't free so if you wish to arrange it, sales or billing can advise you on the cost and arrange one to be shipped to you.
