Why You Might Need to Check Your SIM Number

There are many situations where knowing your SIM number is essential. For example:

You just bought a new SIM card and haven’t memorized the number yet.

You need to share your number with someone for airtime or bank transactions.
You’re registering your line and need the exact digits.

No matter the reason, there are multiple ways to confirm your mobile number quickly.

Method 1: Use USSD Codes to Check Your Number

The most common and reliable way to check your SIM number is through USSD codes. These codes vary by network, but they’re free and instant.

Here are popular ones used in Nigeria and other regions:

MTN: Dial *123# and follow the on-screen instructions. In some regions, you can use *663#.
Airtel: Dial *121# and select the option “My Account” to see your number.
Glo: Dial 1358# to display your number on the screen.
9mobile: Dial *248# and your number will appear instantly.

If you’re unsure of your provider’s code, simply visit their official website or customer care support for accurate information.

Method 2: Check Phone Settings

Your phone often stores the SIM card information automatically. Here’s how you can find it:

On Android:

Open Settings.
Navigate to About Phone or SIM Status.
Tap SIM Card Status – your mobile number may appear under “My Phone Number.”

On iPhone:

Open Settings.
Scroll down to Phone.
Tap My Number – your SIM number should display there.

Method 3: Use Official Mobile Apps

Most network providers have mobile apps that allow users to manage accounts, buy airtime, and check balances. These apps also display your registered phone number once you log in.

Examples include:

MyMTN NG App – available on Google Play and App Store.
Airtel Thanks App.
Glo Café App.
9mobile App.

Downloading these apps gives you not only your number but also full access to data plans, airtime recharge, and customer support.

Method 4: Call or Text a Friend

This is perhaps the simplest trick. Insert your SIM into a working phone and call or text a friend’s number. Your number will display on their screen immediately. This is a quick fix if you don’t remember codes or app details.

Method 5: Contact Customer Care

If all else fails, contacting customer care is the surest way to confirm your mobile number. Simply dial your network’s customer service line:

MTN: 300
Airtel: 111
Glo: 121
9mobile: 200

Once connected, follow the prompts to speak with an agent who can verify your number after a quick security check.
