How to Hide Your Caller ID on Safaricom Kenya’s Network: A Simple Guide

Most of us must have at least in the past if not now been in a situation where they desired to hide our caller ID while reaching out to someone. They way mobile phones are made when someone initiates a call, the recipient would be able to see their names if they had saved that contact in their phone book or at the very minimum see the number that is calling. However, in some I believe very rare instances you might want to call someone without revealing your number to them.

The reasons vary from one person to another, and I must also clarify that some of this approaches are not done in good faith.

In this guide, I am going to outline how you can easily achieve this feature. This guide is for those who want to hide their phone numbers when calling someone for privacy or any other lawfully allowed reason, we are not liable for those using for malicious purposes.
