If you wish to add security to your SIM then enabling SIM PIN is one of the best ways to do so. Now, you might be wondering what the heck is SIM PIN and what is its use. Well, SIM PIN is a pin that keeps other people from using your SIM to make calls, send messages or use mobile data. When it is enabled, your SIM card will be locked automatically when your iPhone restarts or when the SIM card is removed, thus making it unusable. The only way to unlock and use it is by entering the SIM PIN. Sounds useful? You can go through this guide to know how to turn on/off SIM PIN on iPhone.
There is a default SIM PIN for most of the SIMs and may vary depending on your carrier network. So, get this SIM PIN from them if you haven’t already. In case your SIM does not come with an already created PIN then you will have to create it while turning on SIM PIN – the method for which we have mentioned in the procedure below.
Enable SIM PIN on iPhone
1. Open Settings.
2. Select Phone in Settings.
3. Under Phone tap on SIM PIN.
4. Now, toggle the SIM PIN switch to ON state.
5. If you don’t have a SIM PIN you will have to create one. For the users who have it already need to type it and tap Done at the top right corner.
Doing this will turn on SIM PIN on your iPhone.
If you’re using the default PIN then it is recommended to set a new one. You can do so easily by using the Change PIN option under SIM PIN screen. After that, type the existing pin followed by entering the new pin and confirming it.
As mentioned earlier, when SIM PIN is enabled your SIM will lock automatically when the phone is restarted or the SIM is removed and inserted into another phone. You will see Locked SIM on the status bar where you usually see the network signal strength. When locked, it is not possible to place calls or do any operation that is related to SIM.
In order to unlock it, tap on Unlock in the pop-up that appears and enter the SIM PIN. Finally, tap on OK.
This makes it imperative that you don’t forget or lose your SIM PIN.
