IoT Modules Legacy HL Series

Hi,
Does HL7539 support 3G network such as UMTS, CDMA?
I have sent
AT+KBND?
command then reply
0x0010 and 0x0080
It should be UMTS band. So I wonder HL7539 supports 3G as well.
Any information please.

PTS said LTE. I have read it.
My question is why HL7539 respond UMTS band information.
Is it AT command error or connected 3G network?
