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: ![Screenshot from 2021-08-24 16-07-28](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/d/da636d4f1fa006a279fa91aaf9940f58194c57e5.png) 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: ![Screenshot from 2021-08-25 10-37-42](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/1/1e6354cefd8ee2993a5a4c684b269e8b8e93776c.png) Any settings for changing the **connected** state to **yes**?? ---

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? ![image](https://us1.discourse-cdn.com/flex016/uploads/mangoh/original/2X/1/191ded9c4b5796ef2d641fbeea647d95890ec32b.png) ---

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