I found on another website
“FRS/GMRS radios you presently own will function as before, will function in conjunction with newer models, and are grandfathered.”
The FCC changed rules a couple years ago, and wasn’t exactly sure what was going on.
And Amazon sent an email with this
This product has been identified as a dual-service FRS/GMRS radio. Federal Communications Commission (FCC) regulations prohibit the sale or marketing of FRS/GMRS combination devices.
