Changing from a grandfathered T-Mobile One plan


    I was told in store that I could change from my grandfathered T-Mobile One plan to a Magenta plan and keep my discounts that include a free line.

    I was nervous of just doing it there and then so contacted T-Mobile customer service.  The lady was unsure and told me "I may" lose my discounts.  Well that isn't very heart warming to try to change the plan.  Does any one actually know if the discounts are honored from a grandfathered plan?


    Thanks in advance
