OK i probably over looked this, I did search the forums for Sierra modem 4G-LTE only AT commands
i looked at BillA's posts and Jim's posts maybe i just over looked it, but I'm after the AT command for EM7565 and EM7511 to put them in 4g-LTE only mode
found the 4G-LTE only command for Quectel modems
AT+QCFG="nwscanmode",3,1
but need the one for Sierra modems please,.

Well i may have found the string i needed but would like confirmation so i don't do something crazy and brick my modem for Sierra modems it seems to be this
AT!SELRAT=06
would this be correct for LTE only bands?

Don't have those modems but have several other Sierra models (7455/7354). Should be the correct command, worst that could happen is you get an error back when entered.

You can check the currently active bands via:
AT!BAND=?
00 - All bands
01 - Europe 3G
02 - North America 3G
06 - Europe
07 - North America
08 - WCDMA ALL
09 - LTE ALL
Set general band preference via:
AT!BAND=<two_digit_above>
For specific bands use the Sierra band calculator post on this forum.

Reset the RAT to default via:
AT!SELRAT=00
