Apple's self-made iPhone modem rollout plans: A three-year timeline

Apple plans to roll out its own self-made iPhone modem over a three-year period, starting with the iPhone SE in 2025. The company aims to replace Qualcomm modems across its entire product lineup by 2027. Initial versions of Apple's modem will be less technologically advanced than Qualcomm's offerings, supporting only four-carrier aggregation compared to six or more bands supported by Qualcomm's modems. The gradual rollout is due to the risky nature of modem development and the potential impact on device performance.
