I ordered the 863-928 MHz for EU.
And had to set it to EU_868Mhz.
For People in US it's the 902-928 MHz and it has to be set to US_915Mhz.

ok yes its multi band - user can set based on region 433Mhz longer range but not free band in FCC chart - nobody really cares/scans/jams these low power unless its passing via sensitive area.
