How To Check If Your IPhone Is A Carrier-Locked Or Custom Model

If you've ever wondered whether your iPhone is a standard retail model or a carrier-specific (custom) version, this guide will help you find out. Carrier-locked iPhones may have restrictions, such as only working with a specific network provider. Here's how to check:

 

1. Check the Model Number

Steps:

Go to Settings → General → About.

Look for the Model Number (tap it to reveal the full code).

What to Look For:

Standard Retail Model: Starts with M (e.g., MXXXXCH/A).

Refurbished/Replacement: Starts with F (refurbished) or N (Apple-replaced).

Carrier Custom Model: May start with P or have a special suffix (e.g., LL/A for US unlocked, ZA/A for Hong Kong).

 

2. Test with a Different SIM Card

Insert a SIM card from another carrier.

If you see "Invalid SIM" or "SIM Not Supported", your iPhone is likely locked to a carrier.

If it works normally, your iPhone is unlocked.

 

3. Look for "Carrier Lock" in Settings

Go to Settings → General → About.

If you see "No SIM Restrictions", your iPhone is unlocked.

If it mentions a carrier name (e.g., "AT&T" or "T-Mobile"), it may be locked.

 

4. Check the Original Box or Purchase Source

Retail (Unlocked) iPhones: Usually bought from Apple's official store or website.

Carrier-Locked iPhones: Often sold by mobile providers (e.g., Verizon, AT&T) with a contract.

 

5. Use IMEI Checker Tools

Find your IMEI (in Settings → General → About) and check it on:

Apple's official Check Coverage page.

Third-party sites like IMEI.info to see carrier details.

 

Final Tips

Unlocked iPhones work with any carrier.

Locked iPhones may need carrier approval to unlock.

If unsure, contact Apple Support or your carrier for help.

Now you can easily check if your iPhone is a standard or custom model! 🚡
