Are you sure that is a Verizon number?
From one of Verizon's robocall blocking vendor, I can verify that is a Robocaller and the vendor advises not to answer.
Can you give us your ONT's model number so we the CLs here can determine whether you are likely to receive an upgrade?
Furthermore, if you received this robocall on your Fios digital voice line, you can go to your account page and enable Robocall blocker at no charge.
Yes - definitely Verizon number. They verified account info and all.
I do not know the model number of my ONT (it's white rectangular case), but I do know that I could not upgrade my bandwidth past 75 mbps (maybe 100) because it was an old ONT.
Call was on my mobile (profile) number.
The number is legit but most people don't need to upgrade their ONT. This is mostly a way for Verizon to get the customer on the phone to upsell.
