I was wondering if PN had considered allowing customers to increase the initial limit from 3GB to 5 GB for say an additional fee of £1. Its annoying as I just manage to go over 3GB each month so the last few days of each billing month are always restricted.Be even more useful if this would be an option if I was allowed to buy an addition 1GB when I reached the limit. I really dont want to go on PAYG as I prefer the fixed billing structure and really want a sub £20 a month service.
Seeing as it's £1/GB on PAYG and £2.40 (I think) per GB on PAYG Basic, I don't think the chance of you getting 2GB for £1 is very likely.
But, it has been asked before quite a few times for a "bolt on" of extra allowance, so people could use more if they wanted more, but would have to pay for this "extra full speed allowance" if they wanted it.
