Environment
SIM type: SoftSIM
Device: Nordic Semiconductor nRF91 series
Question
Can I provision SoftSIM over-the-air onto my nRF91 module?
Is it possible to flash SoftSIM after the device has been deployed?
Answer
No. The SoftSIM profile has to be flashed over UART.
For provisioning and flashing SoftSIM onto nRF91 series, see this guide:
Cause
Without a valid SIM profile present, the modem will not be able to register on the network and establish a data connection. Hence, you will not be able to communicate with the module or issue any over-the-air updates.
You have to ensure that the SoftSIM profile is successfully flashed onto the module and tested before deployment.
