The watch does not recognize the SIM card - Solutions

The SaveFamily device may fail to detect a SIM card due to issues like inactive SIM, insufficient balance, PIN lock enabled, incorrect SIM size, or poor network coverage. Troubleshoot by verifying SIM activation, balance, disabling PIN, inspecting and reinserting the SIM correctly, testing SIM in another device, and checking device settings. Specific problems include "No Signal," PIN requests, and intermittent recognition, with solutions like toggling airplane mode, restarting, cleaning contacts, or manual network setup.

Problem Description
The SaveFamily device does not detect or recognize the inserted SIM card.

Mandatory Preliminary Checks

1. SIM Card Status

  • Confirm with the operator that the SIM card is activated and operational.
  • Verify that it has sufficient balance or an active data plan (minimum recommended: 500 MB).
  • Ensure the PIN code is disabled (essential requirement for the watch to function).

2. Technical Compatibility

  • Ensure the card is the correct size (most models require a nano-SIM).
  • Verify there is adequate network coverage in the usage area (recommended: 4G/LTE).

Step-by-Step Resolution Procedure

Step 1: Physical Verification of the SIM Card

  1. Completely turn off the watch.
  2. Remove the SIM card from the device.
  3. Visually inspect:
    • Chip condition (no damage or scratches)
    • Contact cleanliness (clean with a dry cloth if necessary)
    • Correct size (nano-SIM for most models)
  4. Correct reinsertion:
    • Orientation: chip facing downward (for most models)
    • Ensure full engagement (a "click" should be felt)
    • Firmly close the compartment.

Step 2: SIM Card Functionality Test

  • Test the SIM card in another mobile device to confirm:
    • Network signal reception
    • Ability to make and receive calls
    • Availability of mobile data
  • If it does not work in another device: Contact your mobile operator.
  • If it works in another device: Proceed to the next step.

Step 3: Device Configuration

  1. Turn on the watch with the SIM card already inserted.
  2. Wait 2–3 minutes to allow automatic detection by the system.
  3. Check the screen for:
    • Mobile network signal icon (with signal strength indication)
    • Name of the mobile operator
  4. If no signal appears, restart the device while keeping the SIM card inserted.

Specific Problems and Solutions

Case 1: "No Signal" or "No Service" Message

  • Activate and deactivate airplane mode (if available on your model).
  • Perform a full device restart.
  • Verify frequency band compatibility (SaveFamily devices generally operate on B3, B7, and B20 bands).
  • Test the device in a different location with known coverage.

Case 2: PIN Code Request

  • Mandatory requirement: The PIN code must be disabled for the watch to function.
  • Disabling procedure:
    1. Insert the SIM card into a standard mobile phone.
    2. Go to: Settings > Security > SIM Card Settings.
    3. Select the option "Disable PIN lock."
    4. Reinsert the SIM card into the watch.

Case 3: Intermittent Recognition

  • Possible causes and solutions:
    • Dirty contacts: Clean the contacts with a dry cloth.
    • Worn card: Test with another SIM card.
    • Insertion issue: Ensure firm and complete engagement.
    • Possible slot damage: Contact technical support.

Manual Network Configuration (if your model allows)

  1. Go to: Settings > Mobile Networks.
  2. Manually select your network operator.
  3. Manually configure the APN if necessary (consult your operator for details).

Note: Most cases of SIM card recognition failure are resolved by verifying card activation, balance/data availability, PIN disablement, and proper physical insertion.
