Does any one know how to force LTE? I keep connecting cdma on ATT in the US, because the reception is not good. I can and sometimes do get LTE with this device, and always with others. How can I force LTE???
You can try the AT command :AT+QCFG=“nwscanmode”,3
If you perform this instruction,in the absence of LTE signal,you may not be able to surf the Internet
For those who might want to use this:
echo -e "AT+QCFG=\"nwscanmode\",3,1" > /dev/ttyUSB2 #set modem to only LTE echo -e "AT+QCFG=\"nwscanmode\",0,1" > /dev/ttyUSB2 # back to auto
<scanmode> Number format, network search mode
1 GSM only
2 UMTS only
3 LTE only
<effect> Number format, when to take effect
0 Take effect after UE reboots
1 Take effect immediately
Do you know if there is a way to check what band the modem is connected on?
There is no direct command,But you can use some other methods

I recently purchased a Mifi Router with a quectel module.I am new on openwrt and i have a question.
How do you send AT commands to the module?
use echo to send command then use cat to get return. use ctrl+c to exit cat
echo -e "AT+QCFG=\"nwscanmode\",3,1" > /dev/ttyUSB2 cat /dev/ttyUSB2
