Quick Answer
To check your remaining MTN mobile data or bundle usage in South Africa via USSD:
- Dial
*136#from your MTN phone line. - Select the menu option for Balances (or dial
*136*1#directly) to view your remaining anytime, night express, or promotional data.
Alternatively, dial *136*2# for direct access to data management and bundle usage menus. USSD balance checks on MTN are completely free of charge and available to both prepaid and contract customers. If the USSD service is temporarily unavailable, you can view your real-time data usage via the official MTN App or MTN Online Chat.
What the Service Is and Who Can Use It
The MTN Data Balance USSD service is an automated self-service tool provided by MTN South Africa. It queries the network’s billing system to display active data balances and remaining bundle allowances directly on your device screen via USSD popups or SMS notifications.
- Eligible Users: Active MTN Prepaid, EverydayGigs, Made For Me, and hybrid/TopUp contract subscribers.
- Prerequisites: An active MTN SIM card inserted into a mobile handset connected to the MTN South Africa cellular network.
- Exclusions: Fully managed corporate enterprise lines with administrative USSD blocks or non-MTN network SIM cards.
How to Check the Data Balance
Before You Start
- Confirm your phone has active cellular signal (MTN 3G, 4G/LTE, or 5G).
- On dual-SIM devices, ensure you select the MTN SIM slot when dialing the code.
- No airtime balance or active data connection is required to dial a USSD code.
Verified Step-by-Step Process
- Open the dialer application on your mobile phone.
- Key in
*136#(or*136*1#for instant direct balance display) and tap Call. - If using
*136#, select the number corresponding to Balances or Summary on the popup menu and press Send. - To view specific sub-bundles (such as Night Express or Social passes), select the designated Data Bundles option within the submenu.
Confirmation or Expected Result
When the query processes successfully, a notification screen will present your active balance summary. MTN typically sends a concurrent SMS message containing a detailed breakdown:
- Anytime Data: Remaining general internet data balance.
- Night Express Data: Off-peak data valid specifically between 00:00 and 05:00.
- Social / App Bundles: Remaining allocations for platforms like WhatsApp or YouTube.
- Expiry Dates: Exact expiration dates and times for each individual bundle.
Note: If you recently purchased a bundle or recharged airtime but it does not immediately reflect on
*136#, wait up to 5 minutes for billing systems to sync before retrying.

Common Problems and Troubleshooting
Code, Session, SIM, or Account Errors
- “Connection problem or invalid MMI code”: This occurs when cellular coverage drops or tower traffic is heavy. Toggle Airplane Mode on and off to reset the network connection, then dial
*136#again. - “Session Timed Out”: USSD sessions automatically close after 10–15 seconds of inactivity. Redial
*136#and enter your menu choices promptly. - Dual-SIM Misrouting: Ensure your device defaults to the MTN SIM for outgoing calls; dialing from a secondary SIM (e.g., Vodacom or Cell C) will result in an invalid MMI error.
When the Service Has Changed or Is Unavailable
System upgrades or network maintenance can occasionally cause short-code disruptions.
- USSD vs. App Discrepancies: Active high-speed downloads or background app data may take 1 to 2 minutes to reconcile in the core USSD database. The MTN App provides the most real-time usage tracking.
- Zero Allocations: If all active data has been consumed, the summary popup will display
0 MBunder active allocations.

- Avoid Unofficial Prompts: Cancel the session immediately if a USSD prompt asks for financial transactions or personal identity credentials to show a balance.
- Fraud Reporting: Report suspicious short-codes or compromised accounts to MTN Customer Care by dialing 135.
