This post will walk you through accessing the updated iOS settings where you can view the number of your iPhone’s SIM card. Here’s a quick guide on how to access and view SIM number on iPhone 13 with the latest iOS 15 interface.

iPhone SIM Number
The SIM number on your iPhone serves as the integrated circuit card identifier (ICCID, a unique serial number that’s specific to your SIM card.
This number is needed for you to access online services from your mobile network provider and for other verification purposes.
The SIM number is also needed in case you lose your iPhone. Thus if you haven’t memorized your SIM number yet, you better take note of it now before it’s too late.
In case you’re wondering how to access this information on your new iPhone 13 aside from the Contacts app, I’ve laid out a quick guide depicting the steps.
Feel free to refer to the outlined instructions to access the iOS 15 menu where your SIM card number is printed.
Easy Steps to Access/View SIM Number on iPhone 13
The following steps are also applicable when viewing the SIM card number on other iOS devices that are running on the same firmware version (iOS 15 or later) with that of the iPhone 13 series.
However, you may see some slight differences on the interface given the fact that actual screens and menu items vary between device models and network service providers. Nonetheless, the overall process is likely the same.
Just follow these steps whenever you’re all set to access the iOS 15 settings where you can view the number of the SIM card inserted into your iPhone 13.
Step 1: From the Home screen, tap Settings to open the Settings app.

Step 2: While on the main settings menu, scroll to find and then tap Phone. Another menu opens with more features relevant to the iOS Phone application.

Step 3: Under the Allow Phone To Access section, find My Number. Your SIM card number will be displayed next to it.

Step 4: To view and manage your SIM card number, tap on My Number. Doing so will open another menu where you can edit your SIM card number.

But before you make any changes, be sure to contact your existing SIM card provider and request a number change.
The number on the SIM card you’re using is not connected to your iPhone. The number that serves as your iPhone’s identifier or primary key is the serial number or IMEI.
If you switch to another network provider, a new SIM card with a replacement number will be sent by your new network provider.
Processing New SIM card Number Request
To request a new replacement number, contact your network service provider using another phone (not your iPhone). You need to let them know that you would like to change the mobile number for your SIM card and state the reason(s) why you’d like to change your number.
If your mobile service provider agrees and grants your request, you will be asked to provide your current SIM card number. Again, you can find that information on your iPhone 13 using the outlined steps above.
Your mobile service provider will then process your request and ask you to do certain stuff like turn your iPhone off while the number is being altered and then turn it back on when the number change is completed. Just do as you told and you should be all set.
If you don’t want to go through these series of procedures, then you can just procure a new SIM card and get a new mobile number in an instant.
And that’s all about viewing the SIM card number on the iPhone 13 through the iOS 15 Phone app settings.
