Koodo Mobile has an offer right now for BYOD (bring your own device) users, offering 2GB of bonus data on their $65 and $75 unlimited Canada-wide calling plans.
After the bonus data, the plans work out to $65 for 4GB and $75 for 5GB each month. The plans come with the usual extras like caller ID, call waiting, etc., and data overages are billed at $5/100MB ($50/1GB).
The promo appears to be available in all provinces except for Manitoba, Saskatchewan and Quebec, since these provinces get better pricing due to regional carrier competition.
If you are on an existing $65 or $75 plan, call in and get your extra 2GB of data.
