Keeping Your Mobile Data Safe When Out and About

Introduction

Staying connected and accessing information on-the-go has become an indispensable part of life for many people. However, this convenience also comes with risks to your sensitive data when using public WiFi or cellular networks. In this article, I will discuss various ways to keep your mobile data safe when out and about.

The Risks of Public Networks

Public WiFi networks available in places like cafes, hotels, airports etc. are convenient but also risky:

Similarly, cellular networks have vulnerabilities:

• SMS text messages are often unencrypted and can be intercepted.
