Hello.
I have a SIM which supports 2 APNs, one public and one private, by configuring it with the command ‘AT+QICSGP =1,1,“private apn”,"","",3’ and then opening the TCP connection ‘AT+QIOPEN =1,0,“TCP”,“Private IP”,9191,0,1’ the connection is established.
But when adding the credentials to the public APN the connection is not created, the command responds OK with ‘AT+QICSGP =1,1,“public apn”,"","",3’ but when sending the command ‘AT+QIOPEN =1,0,“TCP”,“Public IP”,9191,0,1’ the answer is ‘+QIOPEN:0,566’
My question is if there will be any other configuration? to establish a GPRS connection when one SIM supports 2 APNs.
I am using an EC25-MX quectel modem, the model is EC25MXGAR08A02M1G
Thank you
