What is a USSD Code?

USSD codes are special dialing sequences that connect you directly to mobile services. These codes, often formatted as 123# or *1111#, provide instant access to a wide range of services, from balance checks to purchasing data or even configuring call diverts.

No internet connection is needed: All you need is a GSM, 3G, or LTE phone[5].
Services are typically menu-driven: After dialing a code, you’ll see prompts guiding you through various options.
Works across all handset types: From feature phones to smartphones, USSD is universally compatible.

How to Activate a USSD Code

Activating a USSD code is a straightforward process, but knowing the correct format and following menu prompts is crucial. Here’s how you do it:

Identify the Correct USSD Code
- Find the code for your desired service via your mobile network provider or refer to USSDCode South Africa’s activation guide.
Dial the Code
- On your phone’s keypad, enter the USSD code (e.g., *135# for Vodacom self-service[3]).
- Press the call/send button.
Follow On-Screen Menus
- Read each prompt and use your keypad to select options (type the corresponding number and press send).
- For example, to purchase a data bundle, you may be led through several menus: select “Buy Bundle,” then “Data,” then choose the amount.
Confirm the Transaction
- Finalize your selection by confirming when prompted. Some networks may send a verification or request a PIN for sensitive actions.
Service Activated

Memorize frequently used codes for faster access, but always verify from official sources as codes may occasionally change[3].

Safety Tips and Best Practices

Using USSD is generally safe, but vigilance is still required.

Always verify the code before entering personal or financial data.
Use the official menu route (not “direct” codes) for sensitive transactions—menus are regularly updated, and direct codes may sometimes point to the wrong service[3].
Never share USSD codes that involve financial transactions or personal security with anyone you don’t trust.
If unsure, consult official network resources.

Troubleshooting Common USSD Problems

Encountering issues with USSD codes? Here are common fixes:

Invalid Code Error: Ensure you entered the code correctly—missing or extra characters will cause errors.
Service Not Available: The service might be down or temporarily unavailable; retry after a few minutes.
Network Restrictions: Check if your SIM is active and has sufficient signal strength.
Menu Not Loading: Restart your phone or check if you’re roaming, as some USSD services are geo-restricted.

If persistent, contact your network’s support service for personalized assistance.
