eip early payoff

I’ve recently purchased a new phone and am getting a monthly credit for a traded-in device (it was a mother’s day promotion). I would like to pay off the entire amount rather than having to pay monthly and am wondering if I can still keep my promotional monthly credit if I just pay off to close an EIP.

The section below seems to say that it shouldn’t be an issue, but I have seen some contradicting answers.

• If you pay off your EIP early, you’ll continue to receive the promised Recurring Device Credits (RDC) as an account-level credit through the remaining months of the promotional credit period (up to 24 or 36 months).

Thank you!
