And here my problem is that I have the old modems, but I can't test them because I no longer have a land line.

Is there any way to test an internal or external modem without anything except broadband or cellular connections?
It depends if "without anything" is referring to "no additional phone line / service from an external 3rd party" or "nothing at all added to the mix".
I know I can't test the acoustic modems, but I was hoping to be able to test internal ISA and PCI, as well as external modems from 300 baud to 56k. Perhaps there is some inexpensive gizmo available?
It should be quite possible to test slower modems. However, faster speeds, 14.4 / 19.2 / 28.8 / 33.6 / 56, will be more problematic to test.
People are reliably getting modems to connect across VoIP using lossless CODECs, i.e. ULAW / ALAW.
This does take some effort to (initially) set up. But it should be quite serviceable once it is set up.
I think that some companies make Analog Terminal Adapters (ATA) that have two ports, one would connect to each modem, and any number dialed would call (ring) the other port. I /think/ that Grandstream used to make a Handy Tone that did this. Again, this will take some configuration.
I routinely (almost daily) see @Level29_BBS talking about dialing in across VoIP.
