How to convert a 2G sims operating device to a 4G? Answered

I have 2 GSM 2G Sims card  listening devices which is not capable to work on 3g or 4g network.. Since cell phone companies now require a 4g sims card and the listening devices have not advance to work on the 3G or 4G network, I need to convert my device to work on a gsm/wcdma.  The problem is that I don't have an older sims card.  AT&T and T-Model are stating I have to get their 4G sims.  And I can't find a cell phone company still operating on Edge (2g ).  Can anyone help?

Here's a link to show the 2 devices:

You don't have legacy connections where you are? LOTS of people still aren't on a 3g network...where are you?

Basically, no, you can't without replacing the gadget.
