Spitz AX failing to provide internet despite proper sim registration on network

[lizh]

Hi Forsythia:

Now there are two questions:
1,These API interfaces have error “32xxxx”;
If the above situation occurs, please send me the following log.

2, The network is very unstable, sometimes disconnecting?
Please execute the following command:

AT+QCFG="data_interface"
AT+QENG="servingcell"

Thanks!
