Hi Roman～
The sim card is connected with sara-r410. You can refer to <LINK_TEXT text=“https://github.com/SeeedDocument/Wio_LT … master.zip”>https://github.com/SeeedDocument/Wio_LTE_Cat_M1_NB-IoT_Tracker/raw/master/res/WioLTE_Cat_NB1_Eagle-master.zip</LINK_TEXT>. You can use the AT command to control it directly.
Sorry, we do not capture the point, please help clarify “How to I set the Pin for my SIM Card?” thanks.
