# How do I set up or change my SIM PIN?

### Setting a SIM PIN adds an extra layer of security to your device. It ensures that if your phone is lost or stolen, your SIM cannot be used without the correct PIN.

### **What is the default SIM PIN for Meaningful Planet SIMs?**
The default SIM PIN for all Meaningful Planet SIMs is **1111**.
When you first insert and activate your SIM, you may be asked to enter this default PIN. If prompted, please enter **1111** to proceed.

### How to Set or Change Your SIM 
The steps vary slightly depending on the type of device you use. Below are simple guides for the most common platforms.

### **iPhone (iOS)**
1. Open **Settings**.
2. Tap **Mobile Data** (or **Mobile** on some versions).
3. Select **SIM PIN**.
4. Toggle **SIM PIN** on.
5. When prompted for the current PIN, enter **1111**.
6. Choose a new PIN and confirm it.

### **Android Devices**
*(Note: Menu names may vary slightly by manufacturer.)*
1. Open **Settings**.
2. Tap **Security & privacy** or **Biometrics & security**.
3. Select **SIM card lock** or **Set up SIM card lock**.
4. Turn on **Lock SIM card**.
5. When prompted for the current PIN, enter **1111**.
6. Choose and confirm your new PIN.

### What if the default PIN doesn’t work?
If **1111** doesn’t unlock the SIM, it may have already been changed. After **three incorrect attempts**, your SIM will lock and require a **PUK code**.
If this happens:
1. **Do not continue guessing.**
2. Contact **Meaningful Planet Support** and we will provide your PUK code securely.
3. Entering the PUK incorrectly too many times may permanently disable the SIM.

### Can Meaningful Planet reset my SIM PIN?
We cannot reset the PIN directly, but we **can provide your PUK code**, which allows you to unlock the SIM and create a new PIN.
