AT commands for switching modes in Huawei modems with LTE (E392, E398)



If you want to enable only LTE mode for a USB modem, disabling all others, you must use the AT command:
AT^SYSCFGEX=”03″,3fffffff,2,4,7fffffffffffffff,,

In the specified command, the first value is deciphered as follows:
00
– Automatic mode, set by default (priorities in order of priority: 4G > 3G > 2G)
01
– GSM GPRS(2G)
02
– WCDMA(3G)
03
[/b] – LTE(4G)
[b]99
– Leave the current settings unchanged.

You can also choose the order of their priority, in descending order, for example:



AT^SYSCFGEX=”0302″,3fffffff,2,4,7ffffffffffffff,,

In this case, the modem will try to connect first to the LTE network and then to the 3G network, except for working in 2G networks.
or this option:
AT^SYSCFGEX=”030201″,3fffffff,2,4,7ffffffffffffff,,

this is equivalent to
AT^SYSCFGEX=”00″,3fffffff,2,4,7fffffffffffffff,,

Accordingly, automatic mode is set by default (priorities in order of priority: 4G > 3G > 2G)
