supps question

[PhxSunsFan]

I dont sell supps.
I read that when someone gets a supp at T65.. ie no u/w they can select any plan . for ex hi ded G and at the 2 yr mark the carrier will send a letter allowing them to say on that plan or select any supp plan without med u/w? california. can they change anytime before the 2 years and to any carrier?

Unless some state law overrides it, it's carrier specific rule allowing upgrade and must stay w same carrier to upgrade
