What the Service Is and Who Can Use It

The MTN Internet Settings USSD service allows MTN South Africa subscribers to request or configure mobile data parameters automatically.

• Eligible Users: All active MTN Prepaid, TopUp, and Postpaid (Contract) customers using standard handheld devices, smartphones, or basic feature phones.
• Prerequisites: An activated MTN SIM card registered under RICA.
• Exclusions: Fixed LTE routers or specialized home Wi-Fi devices automatically retrieve APN profiles upon SIM insertion. iOS devices (iPhones and iPads) generally do not accept USSD OTA (over-the-air) setting pushes and require manual setup.

How to Get Internet Settings

Before You Start

1. Ensure your MTN SIM card is inserted into SIM Slot 1 if you are using a dual-SIM phone.
2. Ensure mobile data is toggled ON in your device settings.
3. Confirm that you have an active data bundle or airtime for data usage.

Verified Step-by-Step Process

Method 1: Request Automatic Settings via USSD

1. Open your phone’s dialer app.
2. Dial *123# and tap the call button.
3. Select the option for Device Setup or Internet Settings from the interactive menu.
4. Wait for an incoming SMS configuration message from MTN.
5. Open the configuration SMS, tap Install or Save, and enter the PIN 0000 or 1234 if prompted.
6. Restart your device.

Method 2: Manual APN Configuration (Android & iPhone)

If USSD fails or you use an iOS/unsupported Android device, set up the APN manually:

• Android Path: Settings > Network & Internet / Connections > Mobile Network > Access Point Names (APN) > Add New APN. Save the profile and select it.
• iPhone Path: Settings > Cellular / Mobile Data > Mobile Data Network. Under the APN field for Mobile Data, type internet.

Confirmation or Expected Result

• Automatic Setup: You will receive a system push notification or SMS containing configuration profiles. Once saved, a 4G, 5G, or LTE network icon should appear next to your signal bar.
• Manual Setup: Once saved and selected, turn off your phone’s Wi-Fi and open a web browser to confirm data connectivity.
• Recovery: If data fails to work despite correct settings, check your balance by dialing *136# or restart your handset to force a re-registration on the local MTN cell tower.

Fees, Limits, Eligibility, and Processing Times

• Fees: Requesting internet settings via USSD (*123# or *135#) is free of charge.
• Limits: There are no daily limits for requesting settings via USSD.
• Processing Time: Configuration SMS messages typically arrive within 1 to 5 minutes.
• Account Restrictions: Suspended, un-RICA’d, or blacklisted SIM cards cannot receive network settings or transmit mobile data.

Common Problems and Troubleshooting

Code, Session, SIM, or Account Errors

• “Connection Problem or Invalid MMI Code”: Indicates network congestion or low signal. Retry after a few seconds or move to an area with stronger network coverage.
• Dual-SIM Issues: Android devices often attempt to route data through SIM 2 by default. Verify in Settings > SIM Manager that the MTN SIM is selected for Mobile Data.
• Data Not Working After Setup: Ensure Out-of-Bundle (OOB) data usage hasn’t blocked browsing if you lack an active data bundle.

When the Service Has Changed or Is Unavailable

• Reset Network Settings: On Android or iPhone, navigate to Settings > General / System > Reset Options > Reset Network Settings. This clears corrupt APN profiles without erasing personal files.

Official Alternatives

When USSD menu requests are unavailable or fail, use one of the following verified channels:

1. MyMTN App: Download the official MyMTN SA app via Wi-Fi to manage settings, check data balances, and view network status.
2. MTN Customer Support: Call 135 (free from an MTN line) to speak to a customer care agent or receive automated provisioning help.
3. WhatsApp Self-Service: Send a message to the official MTN WhatsApp line at 083 123 0011.
4. MTN Retail Stores: Visit any official MTN store for physical SIM diagnostics or device setup assistance.

The standard USSD code to request automated device setup and internet configuration from MTN South Africa is *123#. You can also access network services via *135#.

Can settings be sent automatically?

Yes, dialing *123# triggers an automated network configuration message to eligible feature phones and Android devices.

What APN values must be verified?

For standard MTN mobile data, the primary APN value is internet. Usernames and passwords should generally be left blank.

Do Android and iPhone steps differ?
