I just called with our ISP about the possibility to remove one SIM card, and the help desk person kept suggesting more things to get rid of.
"That landline, you're still using that? I'd get rid of it. It will save you money. And that data SIM, you barely use it. Seems like it just received some mails or something. You could also drop that. And maybe switch to a lower subscription tier as you don't use that much data anyway."
Best help desk person ever, but probably not the best salesman...
