Bell’s Virgin Plus added a $39/40GB 4G plan on May 31st, but just a few days later, the plan has been removed. As of June 5th, Virgin’s website no longer lists the $39/40GB plan. The $39/20GB 4G plan remains but it no longer has the $5/mo credit that lowered the price to $34.
At the time of publication, Fido and Koodo both still offered $34/20GB and $39/40GB plans. Notably, Fido added its $39/40GB plan in response to Virgin’s offer.
You can check out Virgin’s plans on their website. It's interesting to see how quickly these plans can come and go in the competitive Canadian mobile market.
