I use Westnet however the lowest plan they now have is $15 and you get $200 of free calls per month. Don't think they could make money on people like me! I don't use it often enough -I guess they rely on you going over the limit but as I prefer SMS or email, I don't use phones much.
Canada is reported to have some of the most expensive cellular service in the world. I pay $65 dollars a month for unlimited calls across Canada, unlimited text and 3 gigs of data, all on a 3 year contract. This is a new plan for me and significantly cheaper than my previous plan.
I get free calls to both mobile and land lines after 6.00 p.m. to 6.00 a.m. on my prepaid plan with data thrown in which I rarely use for $30.00/month which rolls over the unused credit each month. When it gets too high I transfer some over to my grandchildren as it saves their mother topping up and suits me as well.
We've been on a NO plan with Vodafone for many, many years now with our mobile calls usually totalling less then $5 a month, so we don't pay anything until it goes over the $5! All outgoing calls, (including o/s calls,) from our landline are FREE! (Vodafone don't have the 'No plan' deal anymore.) It suits us, because we only make 1 or 2 calls a month from our mobiles as well as sending/receiving txts!
