Learn what Samsung SIM lock means, how to unlock it, and how to secure your SIM card. Step-by-step guide for Android users with updated 2025 tips.
What Is Samsung SIM Lock?
If you’ve ever seen the message “SIM locked” on your Samsung phone, you might wonder what it means. A Samsung SIM lock can either refer to carrier restrictions (your phone is tied to one mobile network) or a SIM PIN lock (your SIM card is protected with a security code). Both scenarios can be frustrating if you’re not sure how to handle them.
Understanding how SIM locks work helps you switch carriers, secure your phone, and protect your personal information. Whether you’re trying to unlock a Samsung phone for free or set up a SIM PIN, this guide will walk you through everything.
Types of Samsung SIM Locks
There are two main types of SIM locks on Samsung devices:
-
Carrier SIM Lock
- Your Samsung phone is locked to a specific carrier (e.g., Verizon, AT&T, T-Mobile).
- Prevents you from using SIM cards from other networks.
- Usually applied to phones purchased under contract or installment plans.
-
SIM Card PIN Lock
- A four-digit PIN is required to access your SIM card.
- Protects against unauthorized use if your phone or SIM is stolen.
- Can be enabled or disabled in your Samsung settings.
How to Check if Your Samsung Phone Is SIM Locked
It’s easy to find out if your Samsung device is restricted by a carrier lock:
- Insert a SIM card from a different network.
- If the phone displays “SIM not supported” or “Network unlock PIN required”, it’s carrier locked.
- If it asks for a SIM PIN, that means you enabled SIM lock manually.
For extra details, you can also check your phone’s About Phone > Status Information > SIM Card Status under Settings.
How to Unlock a Samsung Carrier SIM Lock
If your Samsung phone is carrier locked, you’ll need to request an unlock from your carrier. Most carriers provide this service for free once your contract is fulfilled.
Steps to unlock carrier lock:
- Contact your carrier’s customer service.
- Provide your IMEI number (dial *#06# to get it).
- Request a network unlock code.
- Insert a SIM card from another carrier and enter the code when prompted.
👉 For example, you can check official carrier support pages like AT&T Device Unlock or T-Mobile Unlock.
How to Enable or Disable Samsung SIM PIN Lock
If you want to secure your SIM card with a PIN, follow these steps:
- Open Settings.
- Go to Biometrics and Security or Security and Privacy.
- Tap Other Security Settings.
- Select Set up SIM card lock.
- Toggle Lock SIM card ON.
- Enter your current SIM PIN (default is usually 0000 or 1234).
- Create a new PIN of your choice.
To disable, simply toggle Lock SIM card OFF and enter your PIN.
For more details, you can visit the official Samsung Support page.
What to Do If You Forget Your SIM PIN
Entering the wrong PIN three times will lock your SIM permanently until you provide the PUK (Personal Unblocking Key).
How to get your PUK code:
- Log into your carrier’s account portal.
- Call your carrier’s customer support.
- Check your original SIM card packaging.
Warning: Entering the wrong PUK code multiple times can permanently disable your SIM card.
