Method 1: Using USSD Codes to Check Mobile Number

USSD (Unstructured Supplementary Service Data) codes are the fastest way to check your mobile number from SIM. These short codes work on all basic phones and smartphones without internet access.

Universal USSD Codes

• *100 – Works for many carriers worldwide
• *1 – Common in North American networks
• *131 – Used by several European carriers

Carrier-Specific USSD Codes

Here are common codes for major carriers:

• Vodafone: 1112or *555
• Airtel: 1219or *282
• Jio: 1or 701
• MTN: 1231or *663
• T-Mobile: NUM(686)

After dialing the code, your number typically appears on screen within seconds. Some carriers may send it via SMS instead.

Method 2: Checking via Phone Settings

For smartphone users, your device settings often display your SIM number:

Android Devices

1. Open Settings app
2. Tap About phone or About device
3. Select Status or SIM status
4. View My phone number field

iOS Devices (iPhone)

1. Open Settings app
2. Tap Phone
3. Select My Number

Note: If the field is blank, your carrier may not have programmed this information into the SIM.

Method 3: Contacting Your Carrier

When other methods fail, contacting your mobile service provider guarantees you’ll get your number:

• Customer service: Dial your carrier’s helpline (often 611 or a toll-free number)
• Retail store: Visit a carrier store with your SIM and ID
• Online account: Check your profile on the carrier’s website/app

Major Carrier Contact Numbers

• AT&T: *611 or 800-331-0500

• T-Mobile: *611 or 877-746-0909
• Vodafone: 191 or 199 (varies by country)

Method 4: Checking SIM Card Packaging

If you still have your original SIM packaging:

• Look for the number printed on the card holder
• Check the activation documents or receipt
• Review the welcome SMS from your carrier (search your messages for the carrier name)

Troubleshooting Common Issues

When USSD Codes Don’t Work

• Ensure you’re using the correct code for your carrier
• Try removing and reinserting your SIM
• Restart your phone and try again

If Your Number Doesn’t Appear in Settings

• Your carrier may not have programmed the number into the SIM
• Try using a different phone to check
• Consider updating your carrier settings

For Dual SIM Phones

When using two SIMs:

1. Go to Settings > Network & Internet > SIM cards
2. Select the SIM you want to check
3. View the number under SIM information
