[Q] Change network provider name topic

Hello

I have KitKat 4.4.2 factory rom installed on my phone, it's rooted etc. I also have Xposed and Gravity installed.

Does anyone know an easy way to change the network provider name that displays on the lock screen, pull down notification etc? Gravity does not have this feature I do not believe.

I also am considering using the Purity rom, and would prefer not to use Xposed/Gravity on this just in case it cause instability. I don't think Purity has this option either.

Thank you.
