The Magenta plans have been replaced Go5G and Go5G Plus plans.  If you have a Magenta plan, you will continue to have it until you decide that you want to change it to something in-market.  

I will consider your advice when my mom is ready to switch to a Go 5G Plus cell phone plan or rate plan.

boy a sure do love it when I sign up for the best plan so I can have access to new promotions and 2 year trade-ins, etc, then the company replaces my plan with the exact same thing and charges more for it. Plus “Go5G Plus” is such a downgrade name-wise from Magenta Max, which is easily the best plan name ever.
