Good day @Osxar9,
Thanks for your post! The Apple Watch plan is $10 per month when added to a Rogers Infinite plan.
If you choose a Rogers Infinite Extra plan or above and get a free Apple Watch plan for 24 months. Share data from your smartphone plan with your Apple Watch and enjoy worry-free connectivity!
It would be $10 per month if you have a non-Shared plan and it includes 1 GB of data for exclusive use with your watch.
Find more info at www.rogers.com/applewatch - Hope this helps!
