🔐 Important note on the SIM card: Remove PIN - avoid common mistakes

⚠️ Common Mistake: SIM PIN Not Disabled

Many users forget to disable the PIN lock on the SIM card before inserting it.
This can lead to the following issues:

• The gateway does not properly detect the SIM card

• Crashes or boot failures may occur

• The modem fails to register with the mobile network

✅ Recommendation: Remove SIM PIN Before Insertion

To ensure smooth operation, remove the SIM card's PIN lock before inserting it into the gateway.

📶 Additional Causes of Connectivity Issues

Even if the SIM card is inserted correctly, connection problems can still occur.
Possible causes include:

• No mobile signal – the antenna is not receiving
  → Solution: Check the signal strength under
  “Status → Modem Status”
  A signal level below –105 dBm is considered critical

💡 Best Practices

Before inserting the SIM card:

• Disable the SIM PIN lock (e.g. via a smartphone or SIM management tool)

After insertion:

• Ensure the SIM card is properly seated (listen for the clicking sound)

• Check the signal strength

By disabling the PIN lock and following these tips, you can ensure trouble-free operation of your gateway.
