i have had my home number for 20 years, so don't want to lose it. Koodo reception is great on our cell phones in the the house. But just in case the wireless phone isn't the best quality....if I cancel, do I still get to take my number back to Bell, another provider etc?
In fact that's exactly what we did, we signed up with a temporary number and tested it for about a month until we were completely satisfied with the quality - then ported our landline number in. Beware that it will take 3 business days to do so, during that time you can call out on your new line, but receive calls still on your landline.
But as David said, there is nothing to prevent you from going back to a landline if you don't find this satisfactory after all. Though if you're anything like us, you'll never look back. It's so much more cost effective and it's got all the bells and whistles such as voicemail and call waiting chucked in for free!
