An iPad Air M3 with cellular capabilities is a fantastic travel companion, until you try to use a local SIM and it tells you it's locked. A SIM or carrier unlock removes that restriction, letting you use any compatible network with either a physical nano-SIM or an eSIM. Here's how to get your 2025 iPad Air M3 unlocked and working on the network you actually want to use.
Grab your iPad Air M3 and connect it to Wi-Fi. You'll need your IMEI number handy, dial *#06# in the Phone app or head to **Settings** > **General** > **About** and scroll down. Make sure your iPad is running the latest version of iPadOS 18 to avoid any quirks with activation servers.
Check for an Automatic Carrier Unlock First
Most major US carriers handle unlocks automatically now. Once your iPad Air M3 meets their eligibility requirements, they submit the unlock request directly to Apple. The next time your iPad connects to the internet, it unlocks itself silently. You don't need to enter a single code.
Verizon unlocks eligible devices automatically after 60 days. T-Mobile postpaid devices also unlock automatically once paid off. For these carriers, you usually just wait for the confirmation email and let the servers do the work. If your iPad was bought directly from Apple, it's already unlocked.
Getting a Manual Code from Your Carrier
AT&T is the most common carrier that still issues actual unlock codes for iPads. If you're on an MVNO like Cricket or Straight Talk, you'll likely receive a code too. Contact your carrier, verify your eligibility, and request a "SIM unlock" or "carrier unlock" for your iPad Air M3.
You'll need your IMEI and account details handy. AT&T takes up to 7 business days. MVNOs vary. When the code arrives, remove your old SIM, insert a nano-SIM from the new carrier into the tray on the right side of your iPad, and enter the code when prompted.
Entering the Unlock Code on iPadOS 18
If you have a physical unlock code, the prompt to enter it usually appears automatically after you insert a different carrier's SIM card. Type it in carefully. You only get a limited number of attempts before the iPad locks itself to a specific carrier permanently, so double-check every digit.
If you don't see the prompt, try the force restart method: press and quickly release Volume Up, then Volume Down, then press and hold the Top button until the Apple logo appears. This forces the iPad to re-check its SIM lock status. In my experience, this is the quickest way to kickstart the unlock prompt if it doesn't appear naturally.
How eSIM Unlocks Work on the iPad Air M3
The iPad Air M3 is built for eSIM. If your new carrier supports eSIM, you might not even need to touch the SIM tray. However, the eSIM plan won't activate if the iPad is locked. The carrier must unlock your IMEI on Apple's end. Once that's done, you can add the new eSIM in **Settings** > **Cellular** > **Add eSIM**.
I've seen some carriers swear they submitted the unlock but it doesn't go through right away. If the eSIM gives you a "Cellular Plan Not Supported" error, wait a few hours and try again. The activation servers can lag behind. Keeping your iPad plugged into a 20W or higher USB-C PD charger during this process helps avoid interruptions.
Troubleshooting Common Unlock Issues
"SIM Not Supported" after entering the code: This usually means the code was wrong or the iPad isn't fully unlocked. Restart your iPad and try again. If it fails, contact the carrier who provided the code. They can reissue a new one if needed.
Device shows "Unlock Unsuccessful": This can happen if the IMEI isn't clean or the carrier made a typo. Call the carrier back and verify the IMEI they unlocked matches your iPad Air M3 exactly. It's a small detail that trips up a lot of people.
Third-party unlocking services: If your carrier refuses to unlock the iPad, you can use a reputable third-party service. Provide your IMEI and carrier info. They'll usually deliver a code within 24 hours. Avoid services that ask for your iCloud password or claim to do "software unlocks", those are scams for modern iPads. Stick to verified services with clear guarantees.
Battery or charging issues during activation: If your iPad Air M3 battery is low while you're working through this, plug it in with a 20W or higher USB-C PD charger. The iPad may show "Not Charging" with low-power adapters, which could interrupt an eSIM download. Use a certified cable to avoid connection drops.
