How to Find the Model Number on iPhone 15 Pro Max: A Step-by-Step Guide

To find the model number on your iPhone 15 Pro Max, open the Settings app, tap General, then About, and look next to "Model Number". Tap the part number that starts with "M" or "N" to reveal the five-character model number (like A2849). If you can't access Settings, check the fine print on the SIM tray slot.

Why the Model Number Matters

The model number is a unique identifier that tells you exactly which iPhone variant you own. Apple releases different versions of the same iPhone for different regions and carriers. These variants can differ in supported cellular bands, SIM card configuration (physical SIM + eSIM or eSIM only), and even storage options. Knowing your model number is essential when:

• Buying or selling a used iPhone to verify it will work with your carrier.
• Checking compatibility with specific networks, especially 5G and LTE bands.
• Determining if the device is locked to a carrier or unlocked.
• Ordering replacement parts or accessories that are variant-specific.
• Confirming the device is authentic and not a counterfeit or refurbished model misrepresented.

For the iPhone 15 Pro Max, Apple has released several model numbers, including A2849 (sold in the United States, Puerto Rico, and other regions), A3101, A3102, A3104, and A3106. Each corresponds to different frequency support and SIM configurations. For example, the U.S. model A2849 supports only eSIM, while other models may have a physical SIM tray.

How to Find the Model Number in Settings

The easiest and most reliable method is through the iOS Settings app. Here’s a step-by-step guide:

1. Unlock your iPhone 15 Pro Max and open the Settings app.
2. Scroll down and tap General.
3. Tap About at the top of the list.
4. Find the row labeled Model Number. You’ll see a part number like "MXXXXXX" or "NXXXXXX".
5. Tap on that part number. It will change to a shorter five-character model number, such as A2849. This is the model number you need.

Why You Might See a Different Number First

iPhone displays a part number by default (e.g., MU663LL/A) that includes region and configuration codes. Tapping it reveals the actual model number. The part number starts with "M" for retail units, "N" for replacement devices, "F" for refurbished, or "P" for personalized. The model number always begins with "A" followed by four digits.

How to Find the Model Number on the SIM Tray

If your iPhone won’t turn on or you can’t access Settings, you can find the model number printed on the SIM tray slot. Note that this method applies only to iPhone 15 Pro Max models that have a physical SIM tray. The U.S. model A2849 does not have a SIM tray because it is eSIM-only.

Steps for SIM Tray Models

1. Locate the SIM tray on the left side of your iPhone 15 Pro Max.
2. Use a SIM ejector tool or a small paperclip to gently push into the small hole next to the tray.
3. The tray will pop out. Carefully remove it.
4. Look at the slot where the tray was inserted. The model number is printed in very small text on the upper edge of the slot. It will say something like "A3101" or "A3102".
5. You may need a magnifying glass and good lighting to read it because the text is tiny.

What If There’s No SIM Tray?

If your iPhone 15 Pro Max was purchased in the United States, it likely does not have a physical SIM tray. In that case, you must use the Settings method or check the original packaging. The model number is also printed on the box label near the barcode.

Using the Model Number to Identify Your Variant

Once you have the model number, you can determine which specific iPhone 15 Pro Max variant you have. Each model number corresponds to a set of region/carrier specifications. Here are the known iPhone 15 Pro Max model numbers:

• A2849: Sold in the United States, Puerto Rico, and U.S. Virgin Islands. Supports eSIM only, no physical SIM tray. Supports mmWave 5G bands.
• A3101: Sold in Canada, Mexico, Japan, and other regions. Has a physical SIM tray and supports eSIM. Does not support mmWave 5G.
• A3102: Sold in China mainland, Hong Kong, Macao. Has dual physical SIM slots (no eSIM).
• A3104: Sold in most other countries and regions (Europe, Asia, Middle East, etc.). Has a physical SIM tray and supports eSIM.
• A3106: Another regional variant with similar features to A3104 but may differ in specific LTE bands.

Keep in mind that model numbers can sometimes overlap across regions, so it’s best to also check the part number or serial number for a definitive identification. If you need a comprehensive report on your device’s specifications, carrier lock status, and more, you can use our Apple model identification by serial/IMEI service.

Why Variant Matters for Buyers and Sellers

When buying a used iPhone 15 Pro Max, the model number helps you verify that the device will work on your carrier’s network. For example, if you’re in the U.S. and need a physical SIM slot, you should avoid the A2849 model. Conversely, if you travel internationally and need a local SIM card, an A2849 (eSIM-only) might be less convenient. Sellers should accurately list the model number to avoid returns and disputes.

Additional Methods to Find Model Number

Besides Settings and the SIM tray, you can find the model number in a few other places:

• Original packaging: The model number is printed on the barcode label on the box.
• iTunes/Finder: Connect your iPhone to a computer, open iTunes (Windows) or Finder (Mac), select your device, and look under the Summary tab.
• Apple ID device list: Go to appleid.apple.com, sign in, and check the Devices section. The model number may be listed there.
• Third-party apps: Some system information apps can display the model number, but they may require the device to be unlocked.
