What's going to happen to my previous promo bill credits when I do a new trade-in promo?
Current plan: 20 GB Mobile share value plan
Current device Installment plans: 2 devices, iPhone XS max, 6 of 24 payments left. One device gets the BOGO monthly bill credit.
My plan is to upgrade the plan to Unlimited data, which is eligible for the current trade-in($700 bill credit) promotion.
Then purchase two iPhone 12 Pro Max on both lines as an upgrade, and trade-in eligible phones for $700 bill credit for each line; I have spare iPhone 8 and iPhone 6s.
My question is, then, I technically will have two installment plans under every single line. (Total of 4 installment plans)
Is this possible? And would I still get a $700 bill credit for both lines in this case? If yes, what's going to happen to the old BOGO bill credit I mentioned above? Will I still receive this credit as well?
I appreciate any advice.
