If you're in Canada, FIDO is cheap
I have unlimited minutes ANYTIME, 850mins long distance/month, Fax/voicemail, FREE roaming anywhere on fido's network (and now rogers, for $5/month)
All of this for $79 CAD/month
Even if I make an assload of long distance and use the internet on my phone, I never go over $100/month CAD
And fido has way better service than any of the other providers.
