For Better Cell Signal, Buy the A1865 Model of the iPhone X

Starting at 12:01 PDT on Friday, Apple will start selling two versions of the iPhone X in the US: the A1865 version and the A1901 version. If you’re not aware that two models exist, Apple won’t give you an option of which to purchase: you’ll be issued one of the two based on which carrier you’re on. But one of the two models contains an inferior cellular modem, which’ll mean more dropped calls, worse reception, and lower data rates.

The reason why the two models are so different is that they contain different cellular modems. The A1865 model contains a Qualcomm MDM9655 Snapdragon X16 LTE modem, while the A1901 model contains an Intel XMM 7480 model.

The Qualcomm Snapdragon X16 modem is the better modem: it operates considerably better in low-signal conditions, offers better data rates, and supports both CDMA and GSM technologies. The Intel chipset doesn’t work with CDMA networks (such as Verizon and Sprint), and operates less well in areas with weak signal.

If you purchase the iPhone X online and are on a post-paid Sprint or Verizon plan, you’ll be sold the superior A1865 model. But if you’re on AT&T and T-Mobile and purchase online, Apple will ship you the inferior A1901 model, despite the fact that the A1865 model is perfectly compatible with both carriers and offers better reception.

Why don't all iPhones have the better Qualcomm chipset?

This pattern of selling two devices, one with an Intel modem and another with a Qualcomm modem, actually began with the iPhone 7 in 2016. Apple and Qualcomm have been bitter courtroom rivals, with multiple lawsuits between the two companies. Qualcomm claims that Apple has stolen patents, and has asked US trade regulators to ban iPhone imports, while Apple claims that Qualcomm is a “monopoly” and operates an “illegal business model.”

By introducing Intel chipsets into the iPhone in 2017, Apple sought to move away from their reliance on Qualcomm’s chipsets. However, Intel’s cellular chipsets don’t support the CDMA and EV-DO technologies that were built by Qualcomm and used by Verizon and Sprint’s 2G voice and 3G data network. Since many users still rely on 2G and 3G voice and data for calls, Apple could only switch users of AT&T and T-Mobile over to using the Intel chipsets.

How much better is the A1865 model?

We don't know exactly - we haven't seen any definitive tests comparing the two chipsets yet. But tests of last year's iPhone 7 showed that devices with Qualcomm chipsets performed consistently better than those with Intel chipsets in every possible single condition on every cellular band. In some cases the data throughput rates for the Qualcomm-variants were more than twice as fast than the slower Intel-based devices, and they were also able to maintain a signal at weaker signal levels than the Intel versions That means half of Apple's iPhone 7 users experienced significantly fewer dropped calls, better reception in low-signal areas, and faster data rates. 

How to get an A1865 model if you are on AT&T or T-Mobile:

  • Option 1: Go to an Apple Store and purchase in person. Specifically ask for the A1865 model.
  • Option 2: When purchasing online, tell Apple you are on Verizon*. Apple will ask to verify that you are actually on a Verizon account by entering a phone number and some account information. Ask a friend if you can use their account to get through the verification process. When the phone arrives, remove the pre-installed SIM card and replace it with your own, before turning it on.
  • Option 3: Wait until 3-4 weeks after launch. At that time, Apple will likely release a “SIM-free” version of the iPhone X that won’t require a carrier contract to purchase. The SIM-free device sold in the US will be the A1865 model.

* Don’t purchase an Apple phone locked to Sprint. Sprint iPhone’s are sold locked, and you won’t be able to replace the SIM card without getting the device unlocked.

Another way to improve your iPhone's cell phone signal

    If you're stuck with an iPhone 7, iPhone 8 or iPhone X on an inferior Intel chipset, or you generally suffer from signal problems, there's still hope. By amplifying your cell phone signal inside your home or office, you can significantly improve both your dropped call rate and increase data rates. Consider purchasing a cell signal booster for AT&TT-Mobile, or whichever carrier you're on.

        The iPhone X can also face any kind of issue that you may know from the help of the google drive support to generate the following things for you.

        Why is apple selling us equipment at a $1000.00 plus with known reception issues with chip sets. they should be held accountable. I have had my iPhone for approximately 3 wks and have had issues with weak signal any drop calls. AT&T.

        You can now purchase any model iPhone X on the Apple website full price without entering carrier information.

        I’m looking to buy an iPhone X for boost mobile and I was told my an apple employee that no phones sold at apple come locked…. and that boost mobile uses sprint lines so buy a sprint version. He told me none of them will be locked because they are purchased at full price, they are just optimized for that service. So why would one from Sprint be locked?

        This article is incorrect about the Sprint model of the iPhone X. If it is purchased at full price, it is unlocked and can be used on ANY carrier without ever activating on Sprint and without dealing with Sprint at all. Apple Store employees don’t like to share that information with U.S. customers, hoping to reserve the Sprint and Verizon models for customers from overseas (e.g. Asia) that need the CDMA/EV-DO bands.
