What can we do if we don't have a hotspot bottom

I asked them and they believe it is not the carrier problem

They are wrong. It is a carrier feature. They probably need to re-provision your account, assuming you are supposed to have that feature...

Call them back and escalate the call until you get someone who knows what "re-provision" means.

Contact your cellular provider to be certain your account has been provisioned to include hotspot tethering.

Contact your cellular carrier. That's a carrier feature.
