How to Perform a SIM Swap for a Lost Cellphone Number

Switching your SIM card—whether for a lost, damaged, or stolen phone or simply to upgrade to a newer SIM card type—can seem daunting. However, the process of performing a SIM swap is straightforward if you follow the right steps.

This guide explains how to conduct a SIM swap with major South African networks like Vodacom, MTN, Telkom, and Cell C.

What Is a SIM Swap?

A SIM swap transfers your current phone number and associated services to a new SIM card. This is especially useful if:

  • Your SIM card is lost, stolen, or damaged.
  • You’re upgrading to a newer SIM card (e.g., 4G to 5G).
  • You want to switch devices without changing your number.
