What is Wifi Calling and Why Does It Matter?

Wifi Calling allows your phone to use a WiFi network to make or receive calls when mobile signal is weak or unavailable.

Thanks to Wifi Calling, you can:

Make voice calls and send SMS even when you’re deep indoors, in rural areas, or places with poor network coverage.
Keep your phone number and identity—callers won’t notice any difference.
Enjoy clearer calls when WiFi is strong.

This feature is particularly useful for South Africans, where coverage can be inconsistent across provinces. For a deeper look at connectivity solutions, visit ussdcode.co.za’s section on Wifi Calling USSD codes.

Understanding USSD Codes: The Basics

USSD codes (Unstructured Supplementary Service Data) are short codes you dial on your phone to access network services instantly—no internet needed.

Most USSD codes start with an asterisk (*) and end with a hash (#), such as *135# or *100#. They let you activate services, check balances, or change network settings directly from your device, making them accessible on both smartphones and basic phones alike[1][3].

Why use USSD codes?
– They’re fast, compatible with all phones, and work even in low-signal conditions.
– No need for data or mobile apps.
– Secure for managing sensitive functions like banking or activating network features.

Activating Wifi Calling with USSD Codes in South Africa

To activate Wifi Calling, most South African networks allow you to use specific USSD codes or menu options from their master USSD menus.

While not all providers offer direct Wifi Calling activation via a single USSD code, here’s the general process:

Dial your network’s master USSD menu code (usually *135# for Vodacom, *136# for MTN, *180# for Telkom, or *147# for Cell C)[2][3].
Navigate the menu to ‘Network Services’ or ‘Wifi Calling’.
Follow on-screen prompts to enable Wifi Calling, if available.

Some networks may also require enabling the feature in your phone’s settings after dialing the code. If a direct code is not available, you will be guided through the steps by the USSD menu.
