How to Check SIM Card’s Phone Number

Because it’s rare to have to text or call your own cell phone, remembering your own number isn’t very important to most people, especially postpaid users, and doesn’t need to be given out. your contact information to renew the service. However, remembering your cell phone number is just as important as knowing your name. You may even suddenly have to give out your contact information to someone else without a business card. If you don’t know or forget your own contact information, you can check the phone number from your SIM card (mobile subscriber identity module).

Advice

The above methods only apply to standard GSM (Global System for Mobile Communications) phones or devices that use SIM cards to operate.
If you have a CDMA (Code Division Multiple Access) phone or a SIM-free device, you’ll need to call your service provider to find out how to get a phone number.

Warning

Some carriers will automatically cancel service if the SIM card is not used for a certain period of time. If you can’t activate an old SIM card it could be because it’s no longer usable.
