The watch does not recognize the SIM card - Solutions

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.
