If I traded an iPhone 5S to tmobile from verizon that has a year left on contrat how does it work if

[DBZmusicboy01]

It's in good condition.
Will it cause problems with credit score if the contract from verizon is terminated
and how long does it take to get the credit?
Is it possible to trade in the phone on the same day and have the credit right away to get an iPhone 6 same day?

As long as you plan to pay the ETF and any remaining service charges on Verizon then you should be all set in that respect (unless you plan to keep the line and keep on paying it until the contract is done, in case that might be cheaper in some way).
