How benefit me to link my account to my device?

[g-eeee]

Am I missing something? How benefit me to link my account to my device? 

Hi y'all, 

Hope you're well. Totally new to digital world & lost. 

Q1: How does it benefit me to link my account to my device*? 

Is purpose to manage my account online? Seems super-hard to navigate.

* My account: Registered on EE's website. My devices: Mobile is EE, altho' type this on laptop. 

Manage a/c: Eg can see whole of each monthly bill? When click on billing seems directed to a phone no. only?

Q.2: Believe one thing posted somewhere in community is  linked to Meta, correct? 

Sought support for v long time. 

Thanks to hardworking humans for your support.

Best, G

1. Linking your device to an EE a/c helps you manage it. It is not essential but if you are on contract it's the only way to see your bills. Your device is actually represented by the mobile no. of the SIM within it.
2. No, this Community is not linked to Facebook. It is implemented by Khoros - see link at bottom R.
