This article clarifies that if you unplug an LTE SIM card from an SRX device, you need to reboot the device for it to detect the SIM card again; otherwise, the device will not detect it.
Initially, the LTE SIM card works well. However, when the customer unplugs the card and plugs it back in to the SRX device, the device is not detecting the LTE SIM card.

[Tue Feb 25 20:39:29.833 LOG: Info] LTE event: Connection attempt: SIM 1, attempt 3, SIM not found.
Observe that the card is not being detected in the above output.
Both the LTE mPIM and SIM card are not hot swappable. If you unplug the SIM card from the SRX mPIM and re-plug it, you have to reboot the SRX device so that the device detects the SIM card.
To enable the SRX device to detect the LTE SIM card, reboot the device. After reboot, observe that the SRX device can detect the SIM card successfully.
