- The smaller iPhone 18 Pro and iPhone 18 Pro Duo models exclusively use Apple's C2 modem worldwide, making the U.S. iPhone 18 Pro Max unique in its Qualcomm modem usage.
- The iPhone 17 Pro and 17 Pro Max featured the Snapdragon X80 modem globally, but the U.S. iPhone 18 Pro Max includes a newly identified Apple mmWave 5G antenna module.
- Apple has not explained why only the U.S. iPhone 18 Pro Max retains a Qualcomm modem, leading to speculation that it may be related to contractual obligations with Qualcomm through 2026.
- Apple's C2 modem supports ultra-fast mmWave 5G in the U.S. and offers faster uploads with 15% less energy consumption compared to its predecessor, while Qualcomm modems have supported mmWave 5G in the U.S. since the iPhone 12.
