Fyi: Funny but i was on the same plan (24.99) when the new insider (9.99) came out. To be honest i was two days past the two weeks that you can change. I phoned in and spoke c.s.a who would not help me and said it was to late. I asked to speak to someone in loyalty dpt. Stated my concern and they agreed to swith me to the 9.99 plan based that i was with mts for a long period. Yo might want to give it a shot and speak to someone in loyalty dpt. Wish you luck.
