That is a good question. The down payment will remain the same. However if you like to have the trade in value of your device to be applied towards the iPhone 15 down payment, we can do the upgrade to the nearest store in your area. For example, the trade in value of your phone is around $200, that amount will be deducted to $983.99. So instead of paying the $983.99 you will only pay $783.99. Then the remaining trade in promo will be divided to 24 months and will be applied in your bill on a monthly basis just like your current promotion for iPhone 14.
