iPhone 18 Pro Could Use Qualcomm Modem in the US and C2 Elsewhere

Stolen information from Apple manufacturing spouse Tata Electronics appears to uncover that the iPhone 18 Pro volition usage antithetic modem chips depending connected the marketplace it is sold in, with U.S. models retaining Qualcomm hardware portion planetary models volition diagnostic Apple's in-house C2 modem.



The uncovering emerged from a wide-ranging cyberattack connected Tata, which alongside Foxconn assembles the iPhone. More than 630GB of confidential information was stolen by a ransomware radical calling itself "World Leaks" and has been circulating online. The worldly was obtained illegally and MacRumors has not seen the stolen files directly. AppleInsider conducted an investigation of the stolen files and said it could corroborate the authenticity of respective cardinal documents.

Among the accusation that has attracted peculiar is simply a measure of materials seemingly related to the U.S. variant of the ‌iPhone 18 Pro‌, which lists aggregate Qualcomm components alternatively than Apple's C2 modem, codenamed Ganymede. The Qualcomm parts referenced see the SDX80M, SDR875, QDM8771, QDM8720, PMK75, PMX75, and QET7100A, components associated with mmWave 5G support. International ‌iPhone 18 Pro‌ models, by contrast, are said to usage the "C2," which would win the C1 and C1X modems presently recovered successful the iPhone Air, iPhone 17e, and M5 iPad Pro.

The implication, arsenic AppleInsider notes, is that the C2 inactive lacks mmWave capability, and that Apple is erstwhile again relying connected Qualcomm to capable that spread for American carriers.

mmWave is the ultra-high-frequency set of 5G offered chiefly by Verizon, delivering precise accelerated download speeds implicit abbreviated distances. Apple's C1 and C1X modems are wide regarded arsenic much powerfulness businesslike than their Qualcomm counterparts, meaning U.S. ‌iPhone 18 Pro‌ buyers whitethorn spot somewhat worse artillery beingness than those purchasing the aforesaid instrumentality elsewhere.

Daring Fireball's John Gruber offered investigation of the applicable tradeoffs involved. While 5G outpaced LTE successful his tests, Gruber argued the quality has nary meaningful interaction connected however the telephone really feels to use:

Having a telephone that tin propulsion 320 Mbps down implicit cellular is similar having a car that tin spell 320 MPH — an absorbing method feat, but of nary applicable worth to maine whatsoever. I ne'er consciousness similar I'm waiting for thing to load due to the fact that I'm connected LTE. LTE is accelerated enough, and regular 5G is much than accelerated enough. 5G mmWave is simply a discarded of artillery beingness arsenic acold arsenic I'm concerned.

On wherefore Apple would not simply deploy the C2 everyplace alternatively than retaining Qualcomm for the U.S. market, Gruber pointed the digit squarely astatine bearer economics:

Faster-than-you-practically-need download speeds are a bearer bragging point. Longer artillery beingness and plenty-fast-enough download speeds are an Apple bragging point. Verizon — and to a lesser extent, AT&T — spent a luck gathering retired mmWave networks. They don't privation to merchantability flagship phones that don't enactment them. Apple's flagship iPhones person supported those networks since 2020. If Zivkovic's investigation of this stolen information from Tata is correct, and Apple is going to usage Qualcomm's modems lone successful iPhone 18 Pro models sold successful the U.S., I deliberation the crushed wherefore is Verizon and AT&T bragging points, not immoderate applicable idiosyncratic benefit. And the effect whitethorn beryllium that U.S. iPhone 18 Pro models get somewhat worse artillery beingness than those successful the remainder of the world.

The C2 modem has been a rumored diagnostic of the iPhone 18 Pro for years arsenic portion of Apple's broader effort to trim its reliance connected Qualcomm. A divided deployment, with the C2 handling astir of the satellite portion Qualcomm covers the U.S., would correspond a important measurement successful that absorption adjacent if it falls abbreviated of a implicit transition.

The ‌iPhone 18 Pro‌ and ‌iPhone 18 Pro‌ Max are expected to motorboat successful the autumn alongside the archetypal foldable iPhone.
