If you stream a lot of audio, that chews through data quickly, four gigs gives you a couple hours per day of streaming audio of average mobile stream quality.
Though for Canadians it's pretty much impossible to beat Koodo for overall plan cost. Bring your own phone and you get unlimited Canada-wide calling, SMS/MMS/CID/VM/etc. and 5GB data on the Bellus network for $50/m.
In the past four years I've gone from Koodo->Fido->Wind->Koodo, switching whenever a better plan value is available.
And FWIW, I'm not sure that you can simply drop your 6GB plan to 2GB for $15. The 6GB promo plan was $30, but isn't currently in-market or compatible with current in-market plans. I suspect what they're doing is moving you to a current in-market plan that happens to have 2GB of data - you'll want to be careful to compare base plan features if this is the case.
What's koodo's unlimited plan? I'm about to switch from koodo to wind for their $40/mo for unlimited Canada data, text, and calls.
