The A15 would be $11.67 a month on tab mid, for which the minimum plan price is $50 a month.

If you pay $40 up front, you can get it on tab basic, for which the minimum plan price is $35 a month. Your monthly tab payment would then be $10 a month for 24 months.

To add to what Timo said, 

just keep in mind that the $50 plan will come with 60GB of data, Canada wide talk and text, and a perk of your choice. On the other hand though, at the tab basic price point of $35 a month, it only comes with Canada wide talk and text and no data, it is pay per use. So if you use / need data, go with the $50 a month option. But if you don’t need data and haven’t used it before, then go with the Tab basic $35 option. 

You can get a data plan with tab basic as well. $45 for 50 GB at 4G speed.
