Good evening, I use an application for work to access sensitive data that I need to access through my phone. Part of the security is a Mac address check. It's fine on WiFi as I've set the Mac address to be fixed as my device Mac address on my galaxy S21 plus. The problem I'm having is my mac address keeps changing on my mobile data. Is there anyway to have this as a fixed mac address?

@Samkc87 

The easiest way is to use a vpn.

That's what I thought but every time my network loses signal and reconnects so does my mac. I've managed to set my phones mac on WiFi to stick to my device mac but can't seem to do the same on mobile data

@Samkc87 Hi,

All network adapters and network capable devices have a unique MAC address.

Mobile data wont change your MAC address, it communicates by IP address.

A router or server can allow or reserve an IP address to a MAC address ( An individual device or adapter)

@Samkc87 Your phones MAC address can't be changing it's set from the factory, the only way to change your phones MAC Address is to remove the network chip and replace it.

An IP address can be Static (Stays the same) or Dynamic (Changes from time to time) but that is provided by your ISP.

There must be multiple network adapters to generate different ip addresses, surely?
