I'm on a Corporate plan that I signed up on last year. Corp 450 + LTE Data 6G. I didn't have a reason to use the Personal Hotspot feature until recently when my daughter inherited by wife's old Iphone. To my surprise, Personal HotSpot did not work and a message to contact the carrier pop up.
I have been strugling with Rogers the past few weeks where they have tried adding SOC codes to enable but finally today, one of the business reps told me that old Corp plans may not have tethering and that there was no way they could add this to my plan.
