What 4G LTE Router Module Do I Need?

I have a Raspberry Pi4 that is going to be scanning for a wireless 5Ghz internet connection. I have also purchased several EG25-G modules. What product can I use to put my EG25-G into that will send out a 5Ghz signal for my Pi4 to connect to? If possible please include an option for modifications to my existing Pi4 as well as no modifications. I would prefer to have a separate standalone device.

Thank you in advance.
