Need quick access to network-specific codes?
Jump straight to the dedicated operator pages if you only need one network's balance, buy-data, airtime advance, or account shortcuts.
Quick Answer
Common balance shortcuts are MTN *136#, Vodacom *136#, Telkom *188#, and Cell C *101#. MTN now publishes *121*number# for CallBack requests; use the MTN USSD page for the current menu fallback and the still-withheld own-number shortcut. Use this hub for cross-network comparison, then jump to Telkom USSD codes or how to check Cell C balance when the intent becomes network-specific.
For network-price or bundle intent instead of code lookup, go to the Vodacom data prices page. If your query is how to check balance on Vodacom, use the dedicated guide. For broader prepaid pricing research, open the cheapest data comparison guide.
For an MTN-specific walkthrough, use how to check data balance on MTN in South Africa. If you are checking when an off-peak bundle can be used, see the MTN night data time guide instead.

Methodology and trust
Independent analysis: DataCost compiles public network shortcuts and common consumer workflows so users can solve prepaid tasks faster.
Codes and menu trees can change. Where a direct network-wide shortcut is not clearly supported, this page keeps the wording conservative and points users back to the operator menu instead of inventing a direct code.
