GSM modules going out of date on 5G?

Hello i was wondering sense a lot of phone companies are moving to the 5G network. And phones a lot of them even on the 4G LTE networks won’t work no more. then that means theses GSM modules we are using right now soon will no longer be usable. Will there be a anything new coming out that will work? Or do we have to go to a internet network connection type of device?
