I've seen posts saying that you have to wait 90 days to pay off your tab in full. Does that mean if I wanted to get a phone for 0$ with a 504$ tab that I'd pay 21$ a month for, I'd have to wait 3 months (63$) and then I could pay the remaining 441$ after the third month (504-63)?
Currently I am on a 2-phone plan with my dad where he pays around 50$ a month for my phone and around 50$ for mine. About 100$ in total every month. Would I be able to swap my current phone for the new phone that I would have purchased on the Tab Medium and still use the same plan?
