Is mobile data secure?
Yes, mobile data is considered to be secure. It is more secure than public Wi-Fi (though not 100% risk free). Your data is encrypted between your device and the cell tower when you use your carrier’s mobile network, which makes it more challenging for hackers to intercept compared to open Wi-Fi networks.
For mobile data when travelling, the best security measure is to use an eSIM, which offers a secure, private internet connection for your device. An eSIM will give you direct access to local mobile networks, avoiding the dangers of unsecured public Wi-Fi.
You can also improve the security of your device by sticking to secure websites (look for the HTTPS), keeping your device software updated, and using a VPN for sensitive activities.
