Will my wifi cameras that only connect to 2.4 ghz networks work on T Mobile 5g Internet?

Thinking about making the switch to TMobile 5G Home Internet but I think my security cameras only work on 2.4 ghz wifi networks. My current setup allows for me to connect to my router via 2.4 ghz or 5 ghz. Does the tower modem/router thingy from T Mobile push out a 2.4 and 5 ghz signal and you can choose which to connect to?
