2. Follow the options displayed on your screen.

3. Check your MTN data balance by SMS

If you prefer SMS, MTN currently says you can send 2 to 323 to check your data balance.

Open your Messages app, create a new message, type 2 as the message and send it to 323. You should receive your balance information by SMS.

4. Check your MTN data balance with the myMTN app

The myMTN NG app is useful if you want more than a one-time balance check. MTN says the app lets customers check data and airtime balances, track usage, buy data and manage other account services.

1. Install or open the myMTN NG app.
2. Sign in using the available login option.
3. Look for your data balance on the account or home screen.
4. Use the data-tracking features if you want to monitor how quickly your bundle is being used.

5. Can I check my MTN data expiry date?

Yes. MTN says the same balance-check channels can also be used to check the validity and expiry information for your data bundle. You can use *323*4#, *310#, the SMS option, myMTN or Zigi.

What if your MTN data balance is not showing?

If the balance does not appear immediately, do not assume that your data has disappeared. Try the following:

• Repeat the USSD request after a short while.
• Try *310# if *323*4# does not respond.
• Check through the myMTN app if you have mobile internet access.
• Make sure you are checking from the MTN SIM that has the data bundle.
• Check whether you have multiple bundles or bonuses with different expiry dates.

What happens if you have more than one MTN data bundle?

You can have multiple MTN data bundles active at the same time. MTN says each bundle can have its own expiry date, and the bundle with the shortest validity is used first in the applicable cases.

This is one reason checking your balance regularly can save you from wondering why a particular bundle appears to be reducing faster than expected.

How to check MTN data balance without internet

You do not need mobile internet to use the USSD or SMS methods. If your data has finished completely, you can still try *323*4#, *310# or send 2 to 323 from your MTN line.
