Dear Olof: 1. Our AT command “AT^SYSCFG”
can only support to set 2G only, 2G preferred, 3G only and 3G preferred, but can not support 4G setting. 2. The following AT command for query connection mode:
Cur_mode indicates the current network mode: 00: reserved 01: GSM 02: CDMA(including 1x,EVDO) 03: WCDMA 04: TD_CDMA 05: Wimax 06: LTE 07: Wifi ... 99: none Hope that this can help you. Best Regards, Franko Fang -----邮件原件----- Hi Franko! Do you have any information on what AT commands should be issued to toggle force-3G/force-4G/Auto mode and is there a command to query connection mode if set to AUTO?
