if you see something like “NR5G-SA”, Cograts!!!
// Check your 5G SA configuration first
AT+QNWPREFCFG=“nr5g_band”
// Consult your SIM card carrier to determine the local 5G SA bands, then configure the device to match those bands exactly.
// For example, for users in China, the configuration might look like this:
AT+QNWPREFCFG=“nr5g_band”,41:77:78:79
// Set the device to use only 5G and LTE networks
AT+QNWPREFCFG=“mode_pref”,LTE:NR5G
// Enable both 5G SA (Standalone) and NSA (Non-Standalone) modes.
// The value 0 means that neither mode is disabled.
AT+QNWPREFCFG=“nr5g_disable_mode”,0
// Set network priority: 5G > LTE > WCDMA
AT+QNWPREFCFG=“rat_acq_order”,NR5G:LTE:WCDMA
// Reboot the Quectel device
AT+CFUN=1,1
// Query the serving cell information
AT+QENG=“servingcell”
// If you see “NR5G-SA”, congratulations! Your device is connected to a 5G SA network.
