A pair of teardowns have confirmed speculation that Apple used multiple vendors for cellular modems in the iPhone 7 family, with an Intel-made wireless modem found in a model for AT&T and T-Mobile.

A blog post heralding the disassembly of the iPhone 7 A1778 model by Chipworks and TechInsights notes that the Intel Baseband Processor PMB9943 was discovered. In a previous teardown by iFixit, Qualcomm's MDM9645M LTE Cat. 12 Modem was identified.

It was earlier speculated that Apple's shift to two different carrier variants of the iPhone 7 was because Intel had entered the supply chain, and its latest mobile modem can't handle the older CDMA networks used by carriers like Sprint.
