Magenta 55+, do we get an iPhone 18 Pro trade-in deal?

I’m on T-Mobile Magenta 55+ and thinking about upgrading to the iPhone 18 Pro. Does Magenta 55+ qualify for a trade-in promo? If so, how much can we get off with an eligible trade-in? I’m having a hard time finding a clear answer, so I’d appreciate any info from anyone who’s already checked or upgraded. Thanks!
