can reps check if numbers qualify for third line free? - eviltoast

Hey folks, I’m guiding some extended family on switching to T-Mobile from Consumer Cellular (AT&T Sims). They were switching sims with T-Mobile ones from Consumer Cellular, since CC used to support T-Mobile and AT&T.

Anyway, given that switching, I’m worried they may not qualify for the third line free. Is this something that can be verified before they switch?
