Did you change your phone number recently and forget the new one? Or maybe you've found a SIM card and want to find out the phone number assigned to it. As long as you can insert the SIM card into an iPhone or Android phone, you can easily find the attached phone number, even if you're not connected to a network. This wikiHow article will show you how to check the phone number associated with your SIM card.

Asking the Carrier: Dialing, Calling or Texting

Try your carrier's help code. Depending on the carrier, you may be able to call or text a special number that will display the code on the screen.
- T-mobile and Sprint: Dial #NUM# (#686#) in the Phone app.^{[1]

- Telstra: Dial #150# in the Phone app.
- Other carriers, including AT&T and Verizon, don't offer this feature. You can try searching for other carriers and "phone codes" to see if your carrier has a number to dial.
2
Call the service carrier. Some SIM cards do not display their number inside the settings of any phone. In these cases, you'll have to call the service carrier listed on the SIM card to ask.
- If you can't make outbound phone calls, take the card to a store that sells that service carrier's SIM cards. A customer service representative should be able to help you track down the associated phone number.
- If you bought a new SIM card, it may not have a number yet at all. Once you place it into a compatible phone, you'll be able to activate it on the carrier's network.
- If you are calling from the phone using the mystery SIM card, the carrier may be able to detect the number automatically. If not, have the SIM card visible so you can read aloud the serial number.

Send a text message or call another phone. If the SIM card is active, you can text or call another person and ask them what phone number they see. This will work unless the number is private.
