iPhone 18 pro max trade in offers for Business Unlimited Ultimate plan.

Hello, I am currently on the business unlimited ultimate plan with 2 other people. It was the highest plan offered when I switched over 4+ years ago. I was able to trade in for new iPhone 2 years ago and received the $1200 trade in offer. I don’t see any offer online currently for this current plan as they have changed their plan names. I was wondering if anyone knows if the Business Unlimited Ultimate plan is offering the $1200 trade in offer over 24 months. All advice is appreciated. Thank you.
