Should I change from Go5G to Experience More with Appreciation Savings

Hello all, I need some help understanding some what I could do in my situation. Current State: I have Go5G plan with 2 paid lines and 5 Free lines. Here what I was able extract the details as notes below: Go5G: $130 -$10 | AutoPay Discount -$25 | AutoPay Discount -$25 | Service Promo with New Line(ID210004) -$25 | Service Promo with New Line(ID220005) -$25 | 3rd line Service Promo with New Line(ID200012) -$25 | 3rd Line Service Promo with New Line(ID200011) -$25 | Service Promo with New Line(ID250259) PROXY by DIGITS: $0 -$15 | Proxy by DIGITS Discount Basic Mobile Internet w/ 30GB high-speed data - taxes included: $10 -$5 | AutoPay Discount Plans Total: $140 Total Bill (incl. Devices & Add-ons): $139 _________________________________________________________________________________________ I want to add 2 more lines under Get a line on us free promo. As I understand that it is not possible to add it on my current plan as it is retired. So they want to me to the newer plans. I also asked for updated to Go5G Plus but they can't do it. However, I see in plan options that there is a plan called "Experience More with Appreciation Savings" that drops the base plan price to $120+ Taxes and Fees. Plus the MI Line. Would my free lines transfer over as free lines? Would I pay taxes and fees on those frees lines? How much taxes would I end up paying by chance? Would I keep Netflix Perk? I asked T-Fore on FBM and they stated they would be able to add BOGO. That would put my plan to a 9L plan. I tried u/desterpot 9L calc and it states that it would drop my bill further if I add BOGO lines on Experience More but that is without "Appreciation Savings" designation. Also with adding a BOGO can I take advantages of any other perks like port-in or trade-in and get a phone for discount? Would it be 24 months or 36 months? If that is the case, I would consider paying taxes and fees if it drops my bill and gets me BOGO lines. I know there might be a next increase in the bill due to taxes and fees. Please and thank you!
