On this page
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
Use this hub for all-network comparison and quick directory intent. If the query is Telkom USSD codes, MTN USSD codes, or Cell C USSD codes, open the dedicated operator page for the full code set. For borrow-airtime routes, use the airtime advance codes page because eligibility, fees, and repayment rules can differ by network.
For network-price or bundle intent instead of code lookup, go to the Vodacom data prices page or the cheapest data comparison guide.

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.

Frequently Asked Questions
What is the USSD code to check airtime or data balance in South Africa?
Common balance shortcuts are MTN *136#, Vodacom *135#, Telkom *188#, and Cell C *101#. If a code routes differently on your line, use the network-specific USSD page for that operator.
How do I buy data using USSD in South Africa?
Typical buy-data shortcuts are MTN *136*2#, Vodacom *135*2#, Telkom *180#, and Cell C *147#. These let you buy bundles without relying on the app.
What is the Please Call Me code in South Africa?
The format differs by network and can change. This page lists commonly used formats for Vodacom, MTN, Telkom, and Cell C, but if a code fails you should use the operator’s self-service menu or support channel.
Can I borrow airtime with USSD?
Sometimes, yes. MTN has a verified XtraTime route on *151#. Other operators may place airtime-advance access inside their main self-service menus, so this page keeps that wording conservative where direct verification is less clear.
