A different question, but every country has two different frequency bands.
How do you know if the product is working on 908.4 MHz or 916 MHz (for a US product) ?
I just answered you in detail up in your other thread:
But specific to this aspect, the first frequency listed is the primary frequency for that country, and it will be the one used by almost all off the shelf products intended for residential use.
The second frequency listed is intended for higher bandwidth transmissions. Back in the series 500 days (which is where SmartThings hubs are) you would typically only see it for some commercial projects, and you would usually only see it in a complete package where a hub is intended to only work with its own branded end devices.
That’s starting to change with series 700, since many more devices became capable of running at 100 kilobytes instead of 40, including some of the Inovelli and Zooz products, so if you had say, a hubitat C7 hub, you might start to see a lot more traffic on the 916 band. It’s sort of similar to 2.4 versus 5 GHz Mobile communications.
(By the way, some countries have only one frequency, like India, while others can have three. There’s no particular rule about it, it’s just what was requested for that particular region.)

As for how you know, it should be in the technical specifications for the hub.
But in any case, if you do have a Zwave network using both frequencies, your hub will handle the situation automatically. And again, at the time of this posting, you aren’t likely to see it on a SmartThings network.
This is already a few years old … I am hoping you have cracked your HC3 open and figured out how to enable the US Frequency? I am located in Guatemala and there are no regulations or limitations for the use of this frequency.
I’m also searching the way to change frequency from RU to EU after I’ve moved to EU region with all my devices. I will highly appreciate for help.
I’m using Yubii Home (which is like HC3 Lite)
