iPhone 18 Pro and Pro Max will have a complicated modem situation

Apple will be using two modems in theiPhone 18 ProandiPhone 18 Pro Max, according to new revelations from leaked schematics and documents that were stolen from Apple supplier Tata in a cyberattack. In the US, the company will keep using a Qualcomm modem, and the reason seems to be all about the fact that it supports mmWave 5G, whereas Apple's self-developed modems still don't. On the other hand, iPhone 18 Pro and iPhone 18 Pro Max models sold elsewhere will be using Apple's own C2 modem.

Currently, theiPhone 17eandiPhone Airuse Apple modems, while theiPhone 17,iPhone 17 Pro, andiPhone 17 Pro Maxuse Qualcomm modems. Interestingly, with the iPhone 18 Pro and iPhone 18 Pro Max, Apple may be adding support for eSIM in China. Right now iPhones sold in China have two physical SIM card slots, and no eSIM support. The same documents also reveal that the iPhone 18 Pro is getting a new camera, with a sensor ID of 0x905 compared to the iPhone 17 Pro's 0x903. This implies that the iPhone 18 Pro (and the iPhone 18 Pro Max) will be using a new custom developed Sony IMX905 sensor. That's in line with past rumors that claimed this year's Pro models would be getting a main camera with variable aperture. Source
