Quick Answer
Last verified: July 2026
Status: Officially NOT SUPPORTED on major South African networks (Vodacom, MTN, Cell C, Telkom).
There is currently no official USSD code to convert prepaid airtime directly into retail vouchers, shopping coupons, or cash vouchers (such as 1Voucher, OTT Voucher, or Blu Voucher) in South Africa.
Major mobile operators—Vodacom, MTN, Cell C, and Telkom—only allow USSD codes to convert airtime into network-specific bundles (data, voice minutes, SMS) or transfer airtime to another mobile number on the same network (e.g., Vodacom Me2U, MTN Me2U).
Any third-party claim or dial code promising 1:1 airtime-to-cash or airtime-to-voucher conversion without an official operator partnership is almost certainly a scam or an unauthorized middleman scheme.
What the Service Is and Who Can Use It
Airtime-to-voucher conversion refers to taking unused prepaid airtime or contract top-up airtime and exchanging it for a multi-purpose digital voucher (like a retail, electricity, or gift voucher) or a third-party payment pin.
While airtime vouchers (like 1Voucher or Blu Vouchers) can be bought with cash or bank accounts to buy airtime, the reverse action (using airtime to buy a voucher) is restricted across South African mobile networks.
Who is affected:
- Prepaid Users: Can only use airtime for network voice/data bundles or peer-to-peer airtime transfers.
- Contract / Top-Up / Hybrid Users: Monthly recurring airtime allocations cannot be extracted, cashed out, or converted into commercial vouchers.
- Exclusions: Promotional airtime, free airtime bonuses, and active data bundles cannot be converted into any voucher or cash product under any network terms.
Can Airtime Be Converted to a Voucher?
No direct, official network USSD menu exists in South Africa to exchange accumulated SIM airtime for retail vouchers.
Why Is Official Airtime-to-Voucher Conversion Restricted?
- Financial and Banking Regulations: Converting airtime into liquid value or retail vouchers enters the territory of banking and money-remittance services regulated by the South African Reserve Bank (SARB).
- Fraud and Theft Prevention: Airtime can be fraudulently obtained via unauthorized SIM swaps, stolen devices, or compromised accounts. Restricting direct voucher conversion prevents thieves from easily liquidating stolen airtime.
- Network Revenue Rules: Airtime purchased with mobile operators is intended solely for telecommunication services on that specific network.
Scam Warning: Be extremely cautious of social media groups, unverified apps, or informal P2P traders claiming to convert airtime to vouchers or cash for a “small fee”. You risk transferring your airtime and receiving nothing in return.
Confirmation or Expected Result
If you attempt to dial USSD codes for converting airtime to vouchers, here is what you should expect:
- Official Network Codes (*135#, *136#, 180#, 147#): You will only see options to purchase Data, Voice, SMS, or Content Bundles, or to Transfer Airtime (Me2U) to another user.
- Third-Party USSD Shortcodes: Dialing unverified USSD strings (such as
*120*...#or*130*...#) provided by unofficial traders may trigger billing prompts or direct airtime transfers.
If you suspect you have dialed an unauthorized code or shared details with a fraudulent service, monitor your airtime balance immediately by dialing your network’s balance check code (e.g., MTN *136#, Vodacom *135#).
Fees, Limits, Eligibility, and Processing Times
Because official airtime-to-voucher USSD conversion is non-existent, standard conversion parameters do not apply officially. However, related legitimate airtime services operate under the following rules:
| Feature | Official Network Policy / Limits |
| USSD Session Fee | Standard USSD sessions are free or charged at minimal regulatory rates depending on operator/menu type. |
| Voucher Purchasing | Vouchers (1Voucher, OTT, Blu) can recharge airtime, but airtime cannot buy vouchers. |
| Airtime Transfer (Me2U) | Allowed between prepaid SIMs on the same network (e.g., MTN to MTN) with daily balance limits and nominal transaction fees. |
| Airtime to Data Conversion | Allowed on all major networks instantly via standard USSD menus. |
| Reversals | Airtime transfers or bundle conversions via USSD are final and non-refundable. |
Common Problems and Troubleshooting
Code, Session, SIM, or Account Errors
- “Service Unavailable” or “Invalid MMI Code”: Indicates that the shortcode you dialed does not exist on your network.
- “Insufficient Balance”: Appears if you try to transfer airtime or buy a bundle when your balance is lower than required.
- Session Timeout: USSD menus automatically close if no input is detected within 20–30 seconds.
When the Service Has Changed or Is Unavailable
- Fake Social Media Codes: If someone on WhatsApp, Telegram, or Facebook sends you a string like
*136*3*Number*Amount#and promises you will receive a shopping voucher, do not dial it. This is simply the MTN Me2U airtime transfer code, which sends your airtime directly to the scammer’s number.
Official Alternatives
If you need to make use of your remaining airtime balance safely, consider these official alternatives:
- Convert Airtime to Data or Voice Bundles:Use standard network USSD menus to convert your airtime balance into data or call minutes so it doesn’t go to waste at expensive out-of-bundle rates.
- Vodacom: Dial
*135# - MTN: Dial
*136*2# - Telkom: Dial
*180# - Cell C: Dial
*147#
- Vodacom: Dial
- Airtime Transfer to Family or Friends:Use official network Me2U services to share excess airtime with loved ones on the same network.
- Official Mobile Apps & Mobile Money: Services like MTN MoMo or bank apps allow you to buy retail vouchers, electricity, or gift cards directly using bank funds or mobile wallet funds—not prepaid airtime.

Safety and Privacy
- Never share your SIM PIN or OTP: Legitimate operators will never ask for your PIN to complete a service or voucher conversion.
- Beware of MMI Code Manipulation: MMI codes can alter device settings. Do not type shortcodes provided by strangers that start with
**or##as these can enable call forwarding to third parties. - Reporting Scams: If you fall victim to an airtime conversion scam, contact your mobile operator customer service immediately (Vodacom: 082 111, MTN: 135, Cell C: 135, Telkom: 180) to report the recipient number.
Frequently Asked Questions
What is the current USSD Code To Convert Airtime To Voucher?
There is no official USSD code to convert airtime into a voucher in South Africa. USSD menus across Vodacom, MTN, Cell C, and Telkom only support converting airtime into data/voice bundles or transferring airtime to another user on the same network.
Is airtime conversion officially supported?
Airtime-to-data and airtime-to-voice conversions are officially supported. However, converting airtime into general retail, cash, or shopping vouchers is not officially supported by South African operators due to regulatory and anti-fraud restrictions.
Which voucher types qualify?
None. Products like 1Voucher, OTT Voucher, or Blu Vouchers can be used to load airtime onto a SIM, but SIM airtime cannot be used to buy these vouchers.
What fees or limits apply?
Since official conversion does not exist, standard fees do not apply. When converting airtime to data bundles or transferring airtime via Me2U, standard operator bundle rates and minor transfer fees apply.
What should I do if the airtime conversion USSD route does not work?
If you dial a code expecting a voucher and it fails, stop immediately. Do not attempt unverified third-party shortcuts. Use your network’s official self-service app (MyVodacom, MyMTN, Telkom, Cell C) to convert airtime into usable data bundles safely.
