*136#and*136*1#). - Top Up / Hybrid Subscribers: Can view airtime and recurring bundle balances via USSD.

How to Check the Balance
Before You Start
- Ensure your phone has an active MTN SIM card inserted.
- Confirm you have a cellular signal (at least 1–2 bars of network connectivity).
- If using a dual-SIM phone, select the MTN SIM card as your primary dialing line before initiating the code.
Verified Step-by-Step Process
- Open the Phone App: Launch your mobile device’s native phone dialer pad.
- Dial the Shortcode: Enter
*136#(for a standard airtime summary) or*136*1#(for detailed bundle balances). - Press Call/Send: Initiate the action using your MTN SIM.
- View On-Screen Flash Message: A USSD pop-up message will appear displaying your main airtime balance and primary bundle totals.
- Follow Prompts (Optional): If using a multi-option menu, reply with the requested numeric digit to view specific bundle types (e.g., promotional data or social bundles).
Confirmation or Expected Result
When the session succeeds, an instant pop-up window (USSD notification) displays your current balances in South African Rands (ZAR), megabytes/gigabytes (MB/GB), or remaining minutes/SMS units.
If your detailed breakdown includes multiple active packages, you may receive a supplementary SMS containing the exact breakdown within a few seconds of closing the USSD window.

Common Problems and Troubleshooting
Code, Session, SIM, or Account Errors
- “Connection problem or invalid MMI code”: This indicates a temporary network timeout or weak mobile signal. Switch flight mode on and off to reconnect to the cell tower, then redial
*136#. - “Result not showing / Session timed out”: USSD sessions automatically terminate after approximately 30 seconds of inactivity. Redial the code and respond promptly to on-screen prompts.
- Wrong SIM Selection: On dual-SIM handsets, verify that the call is being placed from the MTN slot rather than a second carrier’s SIM.
When the Service Has Changed or Is Unavailable
Network operator maintenance can occasionally cause shortcodes to return error messages. If *136# fails to load:
- Try the master self-service code
*135#and select Option 2 (Balances). - If you need specific settings or bundle queries, see related guides such as How To Check MTN Airtime Usage With USSD Code or MTN Data Balance USSD Code.

Frequently Asked Questions
What is the current MTN USSD Code To Check Balance?
The standard verified USSD code to check your MTN balance is *136#. Dialing this code brings up a rapid view of your remaining airtime balance. Dialing *136*1# opens a detailed breakdown of active voice and data bundles.
Which balance does the code show?
*136# displays your primary prepaid ZAR airtime credit. Using *136*1# or navigating the *135# menu displays secondary balances, including daily/monthly data bundles, night express data, promotional voice minutes, and active SMS bundles.
Must the user dial from a registered number?
Yes. USSD queries query the network hardware tied specifically to the SIM card making the call. You must dial directly from the active MTN SIM card whose balance you wish to inspect.
Is the displayed amount real-time or delayed?
Airtime balances and standard data usages update almost instantaneously. However, heavy data usage during an ongoing active session may take a few minutes to reconcile completely once the session closes.
What should I do if the MTN USSD route does not work?
If *136# is unresponsive due to network maintenance, dial *135# as a secondary option, check your balances via the free MyMTN App, or text “Balance” to MTN’s official WhatsApp channel at 083 123 0011.
