Reader SIM troubleshooting

Payment issues typically come from MDB wiring, reader configuration, or settlement mismatches. Fix SIM and cellular connectivity.

• Inspect MDB harness and pins for damage.
• Verify reader configuration and enablement.
• Compare transaction logs to settlement reports.

• Reseat harnesses and confirm power levels.
• Reprovision reader settings and test small transactions.
• Contact processor support if settlements mismatch.

• Perform a monthly test vend on each reader.
• Keep firmware and software versions documented.
• Review payout schedules with accounting.

• Issues persist after a controlled test and documented settings.
• Errors repeat across multiple machines or locations.
• You need replacement parts or manufacturer diagnostics.
