Complete USSD Codes to Check Your Airtime and Data Balance
Knowing exactly how much airtime or mobile data you have left on your phone is critical to avoiding awkward disconnections during vital phone calls or internet browsing sessions in Nigeria. However, because each of the big four telecommunications providers—MTN, Airtel, Glo, and 9Mobile—routinely updates their USSD protocols and shortcodes, memorizing the correct dialing numbers can feel confusing. Recently, the Nigerian Communications Commission (NCC) mandated a harmonization of several USSD codes to enhance consumer convenience. Let us explore the easiest ways to view your balances today.
Checking Your Balance on MTN Nigeria
MTN has gradually migrated many of its legacy codes to the new NCC harmonized structures, but several classic codes still function flawlessly.
- Airtime Balance: Dial
*310#(New Harmonized Code) or*556#(Legacy Code). A popup notification will instantly display your main account balance, along with valid expiration dates if applicable. - Data/Internet Balance: Dial
*323#or use the legacy code*131*4#to view all active data bundles and bonus internet data pools. - Bonus Airtime: Dial
*310*1#to scrutinize various bonus pots such as Awuf4U or promotional weekend credits.
Checking Your Balance on Airtel Nigeria
Airtel frequently rewards its loyal customers with massive voice and data bonuses. Monitoring them properly guarantees you fully exhaust them before they expire.
- Airtime Balance: Dial
*310#or*123#. The USSD window will present your core balance. - Data/Internet Balance: Dial
*323#or*140#. Airtel prefers to send the comprehensive data balance breakdown directly as an SMS within 10 seconds of dialing the code. - Voice Bonuses: Dial
*123*1#directly or navigate the primary*123#menu to find your specific promotional voice minutes remaining.
Checking Your Balance on Glo Nigeria
Globacom, famously known as the 'Grandmasters of Data', provides multiple avenues to track heavy subscriber usage metrics.

*310#or the classic*124*1#to access real-time notifications of your main voice and SMS credits. - Data/Internet Balance: Dial
*323#or*127*0#. Alternatively, you can send an SMS containing the word "INFO" to 127. - Berekete/Extra Bonuses: Glo often attaches bonuses directly to recharge events. Dial
*124*2#or check the trailing notifications after a balance inquiry to view accumulated rewards.
Checking Your Balance on 9Mobile
9Mobile has historically championed simple, memorable interfaces and standard checking mechanisms.
- Airtime Balance: Dial

*323#or*228#. The system displays your active MB/GB allocations vividly in a USSD popup overlay. - Moreflex/Bonus: Dial
*232*1#or follow the Moreflex specific menu when subscribed to such a package to see hybrid airtime-data equivalences.
Why Do USSD Codes Sometimes Fail to Work?
Occasionally, you might dial a balance code and receive an error such as "Connection Problem" or "Invalid MMI Code". Whenever this happens, it is usually due to transient network congestion in your immediate geographical area, or a temporary maintenance upgrade on the telecom provider's servers. The best troubleshooting step is to wait approximately 3 to 5 minutes, toggle airplane mode on and off, and attempt to dial the code again. Moreover, ensure that your phone is accurately registered to the network's 3G/4G/5G signal tower.
Frequently Asked Questions (FAQs)
Have all the old balance codes stopped working?
Not entirely. While the NCC introduced the universal harmonized code *310# across all networks for easier memorization, many networks have concurrently kept their legacy codes running (like *556# on MTN) to accommodate older subscribers who are accustomed to those historical formats.
Can I check my balance without USSD?
Absolutely! All four networks operate heavily-invested mobile applications. Simply download "MyMTN", "Airtel Thanks", "Glo Cafe", or the "9Mobile App" from your app store. Logging in over an active internet connection provides you with a rich dashboard reflecting your airtime, data, SMS, and historical usage in visually pleasing graphs.
