Apple wanted to use Qualcomm’s LTE modems in the iPhone XS and iPhone XR this year, but according to Apple COO Jeff Williams, Qualcomm refused to sell Apple its chips due to their current legal disputes.
After using both Intel and Qualcomm modems in the 2017 iPhone lineup, Apple says it planned to use chips from both companies again on the 2018 iPhones. Qualcomm’s refusal to sell Apple chips forced Intel to scramble to make up for the extra production.
