Sim pin off

Hey there, htet246,

Thanks for stopping by the Apple Support Communities. If we understand, you'd like help turning off the SIM PIN. We're happy to be of assistance!

You can find instructions on turning your SIM PIN off in the Apple Support article Use a SIM PIN for your iPhone or iPad - Apple Support, shown below:

"Turn your SIM PIN on or off

1. If you have an iPhone, go to Settings > Cellular > SIM PIN. If you have an iPad, go to Settings > Mobile Data > SIM PIN.
2. Turn on your SIM PIN or turn it off.
3. If asked, enter your SIM PIN. If you've never used one, enter the default SIM PIN from your carrier. If you don’t know the default SIM PIN, don't try to guess it. Check your carrier's customer service page or the documents that came with your wireless plan. Or you can contact your carrier.
4. Tap Done."

If you are unable to turn the SIM PIN off because you're prompted for the PIN and you don't know it, use the "If you forgot or don't know your SIM PIN" section of the same article. For further assistance, you will need to get in touch with your wireless carrier for additional assistance: Wireless carrier support and features for iPhone in the United States and Canada - Apple Support.

Best.
