!DASBAND Set frequency band
Set the modem to use a particular frequency band. You must use this command to select
an appropriate band before running LTE, WCDMA, or GSM commands. See page 161 .
Requirements:
Before this command can be used:
•
Use !DAFTMACT to enter FTM mode.
Password required: Yes (see !ENTERCND for details)
Usage:

OK
(Note: For LTE frequency bands, even though the response shows 0
instead of <rfband>, the band has been set correctly if the response
shows ‘OK’.)
Purpose: Set frequency band.

Product Technical Specification document for details.
