No - don't ever sign up as I did join them as it full of crap service - download was often too slow, icq, msn messenger sometimes doesn't work, can't send any email on these smtp outgoing mail server. It kept dis-connected me for no reason after 1 minute. I had cancel it but they kept asked me too many question of why the reason I want to cancel but they ask me to confirmed to cancel by writing by letter not email. Breathe is lots of rubbish of offer!
I tried their 'unlimited' service for a month. It was ok for nearly 3 weeks, but then I was continually getting cut off, often after only a few minutes. I emailed them twice about it, but a week later, with no response, I'd had enough and cancelled.
A couple of weeks later they emailed me (twice) advising me to check my phone line, modem etc etc, but of course by that time I was no longer a customer - anyway, I'd never had any trouble with my computer or phone with any other ISP before, nor have I since, come to that.
