Some Cisco vEdge 100m routers are unable to read the subscriber identification module (SIM) card due to a defective SIM card socket.
Some Cisco vEdge 100m routers manufactured between August 2019 and June 2020 might contain a defective SIM card socket. The defective socket lacks a robust electrical path to the contacts on the SIM card and can result in SIM card read errors.
Affected routers will report problems registering the SIM card and show the SIM status as "not present". In some instances, the cellular LTE modem will go offline or disappear from the hardware inventory entirely. In order to view the SIM card status, enter the CLI commandshow cellular statuson the router console or remotely via vManage as shown in this example:
show cellular status Modem status : Low Power Mode SIM status : Not present Activation status : Not applicable Radio mode : No Service Signal strength : No signal Network status : Not registered Last seen error : SIM Read error
The WWAN Signal Strength LED on the router's front panel might display red (no signal) or might be off (LTE modem disabled).
First, verify that the SIM card is good. Verify it functions correctly in a different Cisco vEdge 100M router, if one is available.
Some intermittent SIM card read failures might be corrected by reseating the SIM card in the SIM socket. Follow the instructions in the Hardware Installation Guide for vEdge Routers, Chapter: vEdge 100m Router for details on how to correctly install the SIM card into the SIM card socket.
If the problem cannot be corrected by reseating the SIM card, the router must be replaced. Replacement is fix on failure.
A router must meet these conditions in order to qualify for fix on failure replacement:
In order to determine if your particular router qualifies, enter the serial number into the Serial Number Validation Tool. The serial number of a Cisco vEdge 100M router can be located with one of these methods:
