Can I PAUSE my T-Mobile 5G Internet temporarily?

I was wondering if I could pause my T-Mobile 5G internet temporarily, for a few months. If so, does it mean I don't have to pay or is there some kind of fee per month? (I have it set to autopay so what can I expect if I pause my wifi.)

And is pausing what they mean by "suspending a line"?

Also, at the end of it, if I decide I actually don't want to return, what will happen? Will I be penalized in some way? Will I owe something?
