How To Use A USSD Code

If you’ve never used one before, it’s simple: open your phone’s dial pad like you’re making a call, type the full code exactly as shown (including all the * and # symbols), then press the call/dial button instead of typing a number. A pop-up menu or text response will appear on screen — follow the prompts from there. USSD sessions are completely free, work without airtime or data, and function on any phone, from the most basic feature phone to the latest smartphone.

Why USSD Still Matters in 2026

With apps and online self-service becoming more common, it’s fair to ask why USSD codes still matter. The honest answer: reliability and access. USSD doesn’t need a data connection, doesn’t drain your battery loading a webpage, and works identically on a R500 feature phone and a R20,000 smartphone. For the millions of South Africans managing mobile accounts on prepaid, tight data budgets, or older devices, USSD remains the fastest and most dependable way to interact with your network — which is exactly why Cell C, along with every other major South African network, continues to maintain and expand its USSD menu rather than retiring it in favour of app-only service.

A Note on Changing Codes

USSD codes are set by Cell C and can occasionally change without much public notice, particularly for less commonly used services. If a code in this list doesn’t respond as expected, it’s worth trying the alternative route through the main *147# menu — most services are accessible both via a direct shortcut code and by navigating the main menu, so if one path stops working, the other usually still gets you there.

USSD vs. The Cell C App: Which Should You Use?

Both methods work well, but they suit different situations:

• USSD wins when: you’re out of data, using a basic phone, need something instant without waiting for an app to load, or you’re in an area with weak signal where data connections struggle but voice/USSD sessions still connect
• The app wins when: you want a visual breakdown (especially for data usage split across multiple bundles), you’re managing several account settings at once, or you prefer not to memorise codes

Many Cell C users end up using both — USSD for quick balance checks and Please Call Me on the go, and the app when they want to actually manage bundles, review detailed usage history, or make a purchase with a saved card.

Common Mistakes When Using USSD Codes

A few small errors account for most “it’s not working” USSD complaints:

• Typing a space or extra character — codes must be typed exactly as shown, with no spaces between the * and # symbols and the numbers
• Pressing “send message” instead of “call” — USSD codes are dialled like a phone call, not sent like a text; using the wrong button on some phones sends it as an SMS instead, which won’t work
• Not waiting for the session to fully load — on a weak signal, the response can take a few seconds; navigating away or redialling too quickly can interrupt the session
• Assuming all codes work identically across networks — a code you remember from a previous MTN or Vodacom SIM won’t necessarily work the same way on Cell C, since each network sets its own USSD structure even where some codes happen to overlap

How Cell C’s Codes Compare To Other Networks

If you’ve switched from another network, or manage phones on multiple networks for family members, it helps to know the equivalents aren’t identical:

This is exactly why porting your number between networks can briefly feel disorienting — muscle memory from years on one network doesn’t automatically transfer. If you’ve recently switched to Cell C, it’s worth deliberately relearning *147# and *101# rather than defaulting to whatever you used before.

Frequently Asked Questions

Do USSD codes cost anything to use?

No — USSD sessions are free on Cell C, regardless of your airtime or data balance.

Can I use these codes on any phone?

Yes, USSD works on any GSM-capable phone, including basic feature phones without internet access.

What if a code doesn’t work for me?

Try the equivalent option through the main *147# menu, or contact Cell C customer care on 135 (free from a Cell C number) or 084 135 (other networks) to confirm the current code for that service.

Are these codes different for prepaid vs. contract customers?

Most core codes (balance checks, Please Call Me, tariff changes) work the same for both. A few services, like certain bundle promotions, may only be available to prepaid or only to postpaid customers — the menu will tell you if a service isn’t available on your account type.

Is there a limit to how often I can use a code like Please Call Me?

Cell C does apply fair-use limits to free services like Please Call Me to prevent abuse of the system, though normal personal use is very unlikely to hit any limit.

Can I set up my own shortcuts for codes I use often?

Most smartphones let you save USSD codes as contacts (name the contact something memorable and save the full code, including * and #, in the number field), so you can dial it like a regular saved contact instead of retyping it each time. This is a handy trick for codes you check daily, like *101# for balance.
