How to Check Airtime Balance (Step-by-Step)

Let’s walk through a typical scenario. Let say you’re in Ikeja, Lagos and you just want to check how much airtime you have before making a call.

Step 1: Make sure your MTN line is active and you have network.
Step 2: Dial *310# on your phone’s dialer.
Step 3: Press send / call.
Step 4: Within seconds you should see a popup or SMS with your current airtime balance amount.
Example: You dial *310#, press send. You receive a message: “Your airtime balance is ₦328.50. Validity: 11-Oct-2025.”
Step 5 (optional): If you see that you have less than the amount you need for your next call or data purchase, recharge immediately.

Tip: If *310# doesn’t work (for unusual cases), you can use the MyMTN App or call customer care to verify your balance.

How to Check Data Bundle Balance and Bonus Data

Now let’s look at data you want to use your bundle wisely, avoid running out mid-download, and know about any bonus data you have.

Step-by-Step for Data Balance

Step 1: Dial *323# or *323*4#. This will bring up your data balance and bonus.
Step 2: A message or prompt appears telling you: “Main Data Balance: 1.24GB, Bonus Data: 300MB – Valid until 30-Oct-2025.”
Step 3: If you also want the validity expiry date, you might need to open the MyMTN App or go via SMS (text 2 to 323).
Example Scenario: You just downloaded a big file but noticed data is low. You dial *323# and see you only have 150MB left of your bundle, but you also have 50MB of bonus that expires in 1 day. Great info — you decide to postpone large downloads until after you recharge.

What about bonus data?

Yes many bundles come with bonus data (for streaming, night usage etc.). The same code *323# often shows both your main data and bonus data balances. It’s important to use bonuses before they expire.

Alternate methods

Use the MyMTN NG App: Open → Data / Usage → shows your balances.
Via SMS: Text 2 to 323 (for Always-On bundles etc.)

How to Check Bonuses (Voice/Data Bonus, Airtime Bonus)

Bonuses are things like extra airtime or extra data you got from special offers, or bonus minutes. It’s also important to know how to check them.

Airtime Bonus

If you’re on a tariff plan that gives airtime bonus (e.g., recharge of ₦100 gives you ₦300), you’ll usually get a message showing your bonus credit. To check:

Dial *310# (this usually shows your total balance including bonus).
Or check via MyMTN app under “Account Info”.

Data Bonus / Night Bonus / Streaming Bonus

These might need the same *323# code or special codes depending on the promotion. For example, MTN’s “YouTube Night/Day” bonus specifies you can check via *323*4#, *310# or text 2 to 323.
Example: You get a text: “You have 300MB YouTube bonus valid until midnight 15-Oct.” You dial *323*4# and it shows remaining 180MB under bonus category.

Validity is key

Bonuses often expire earlier than main bundles. Always check expiry date and use them before they vanish.

Using the MyMTN App & Other Digital Methods

If you prefer graphical interface rather than USSD, this is how:

Download MyMTN NG App (from Google Play or Apple App Store).
Log in with your MTN number and OTP.
The dashboard shows your airtime balance, data bundle, bonus balance, remaining validity.
You can also manage bundles, opt out of some services, and check usage analytics.
The Zigi Chatbot (via WhatsApp or MTN website) can also help you check balances by messaging.

These methods are convenient especially if USSD is slow or you prefer a visual breakdown.

What to Do When Codes Fail or You Get Wrong Balance

Even with the correct codes, you might encounter issues. Here’s how to handle them:

Common issues & solutions

Code returns error or doesn’t respond: Possibly network maintenance or SIM not properly registered. Try again after a few minutes or contact MTN support.
Balance shown is wrong: For example, airtime is less than you know you had, or data shows zero when you bought a bundle. Use the MyMTN App to check and then contact support.
Bonus not showing: It might be expired or conditions not met. Check SMS for expiration, or dial *323# to verify.
Codes keep changing: Stay updated because MTN and regulators can harmonise USSD codes. Online sources show this happened recently.

When to contact customer care

If your code fails multiple times, or your balance is clearly wrong, reach out to MTN customer service (via 300, or MyMTN App) and give them your issue, SIM number, and any reference.

Tips to Make the Most of Your MTN Balance

Here are practical tips Nigerian users can apply:

Check before making big calls/data downloads: Use *310# / *323# so you know you have enough credit.
Watch out for expiry: Know your bundle and bonus expiry dates so you don’t lose usage.
Use night or social bundles: If you often stream or download at night, go for bundles that give you value and check them via the codes so you know how much time you have.
Avoid VAS and unwanted subscriptions: Check via MyMTN if you have active value-added services eating your airtime.
Track data usage: In the MyMTN App you can see how fast your data is burning; use the code *323# regularly to see remaining data.
Share data or airtime wisely: If you gift data or airtime, check your remaining balance after the transfer.
This are the little tips on How to Check MTN Airtime Balance, Data Balance and Bonuses.
