Causes

SIM card absent or not seated correctly
Damaged or corroded SIM card or SIM reader contacts
SIM profile inactive, suspended or subscription expired
SIM PIN/PUK locked
Telematics modem/TCU hardware or firmware fault
Power, ground or fuse problem to telematics unit

Symptoms

No telematics/connected services (InControl, SOS, remote functions)
Telematics unit reports 'SIM error' or 'No SIM' on diagnostics
Stored B116F (SIM card) fault in ECU/TCU memory
Inability to register on cellular network (no signal)
Intermittent connection dropouts or service unavailable messages

What to check

Read stored DTCs and freeze frame data with a compatible diagnostic tool
Verify telematics module is powered: measure TCU supply and ground voltages
Physically inspect SIM card: presence, orientation, corrosion or damage
Check SIM seating and locking mechanism; reseat SIM using vehicle procedure
Check SIM ICCID/IMSI and network registration status via diagnostic scanner
Confirm subscription status and provisioning with service provider/Land Rover

Signal parameters

SIM ICCID (SIM identifier)
IMSI (subscriber identity) and MSISDN (phone number)
Network registration state (registered / searching / denied)
RSSI, RSRP, RSRQ or other cellular signal strength/quality metrics
APN and PDP context status
SIM PIN/PUK lock state

Diagnostic algorithm

Use a diagnostic tool to confirm and record DTC B116F and any related codes.
Check TCU power and ground at the module; verify proper supply voltage with ignition per OEM spec.
Inspect and reseat the SIM card following manufacturer procedure; check for visible damage or corrosion.
With diagnostic tool, read SIM ICCID/IMSI; confirm SIM is detected by the modem and not PIN locked.
Verify network registration and signal strength; if no registration, test the same SIM in a known-good phone/modem to confirm service.
Confirm subscription/provisioning status with Land Rover/telecom provider; ensure APN/settings are correct.
Inspect antenna coax and connectors for damage; measure antenna continuity where applicable.
If SIM and network are functional, attempt TCU/software reset and reinitialize modem; reflash TCU firmware if advised by OEM service information.
If fault persists, replace SIM with known-good unit and retest. If still present, consider TCU/modem replacement following OEM procedures.
Clear stored DTCs and re-test vehicle functions and network registration; log results and advise customer of needed subscription actions if applicable.

Likely causes

SIM fell out or was refitted incorrectly during service
SIM electrical contacts dirty or bent
Service subscription cancelled or not provisioned
Modem failed to initialize due to firmware corruption
Intermittent power to TCU (blown fuse, loose connector)
Poor cellular coverage or faulty antenna coax/connector

Fault status
