Configure the MangOH Yellow(with WP7702 module) board to use External SIM(Airtel) Slot

[pallavibathala]

Hello,

I am Pallavi, Using MangOH yellow board for bringing up an IoT Application.

The board by default was configure to use eSIM. But I wanted it to be configured to use External SIM.

I was trying the below AT Commands for configuring:

Please guide me with proper AT commands for configuring the board to use External SIM.

“UIMS:0” already means it is using external sim slot

Thanks.

Using AT command, How do I check whether the Data call service is active or not??

Do you mean the data service to the yocto linux?
I don’t see any AT command can give such information.
Normally you need to check in console by “cm data”
e.g.:
root@swi-mdm9x28-wp:~# cm data
Index: 1
APN: hkcsl
PDP Type: IPV4
Connected: yes
Interface: rmnet_data0
Family[IPv4]: inet
IP[IPv4]: 10.109.95.162
Gateway[IPv4]: 10.109.95.161
Dns1[IPv4]: 10.144.148.129
Dns2[IPv4]: 10.144.148.5

cm data output is as follows:

Any settings for changing the connected state to yes??

You can use “cm data connect &”

Hello, I am having similar problem. I am not able to activate the external SIM.
I have tried the AT commands (attached). Also the CUSTOM commands, as mentioned Sierra Wireless AT command guide, are throwing errors.
Could you please list down the stesp/AT commands to enable this?

Additionally, is it must to set OCTAVE=0 to enable the external SIM?

[jyijyi]

you can try AT!UIMS=0 to use sim slot 1

Thanks, it worked. I am able to attach to GPRS using my SIM.
