You may see one or more of the following:

  • "Missing SIM"
  • "No SIM Card"
  • "SIM Not Detected"
  • No cellular signal
  • Unable to make or receive calls
  • Unable to send messages using cellular service

Common Causes

The most common causes include:

  • SIM card not installed correctly
  • SIM Lid Protector loose or missing
  • SIM card missing from the watch
  • SIM card not activated
  • Airplane Mode enabled
  • Poor cellular coverage
  • SIM card damaged during installation

Step 1: Confirm Which Version You Purchased

AT&T and T-Mobile versions of TickTalk 5 include a pre-installed SIM card.

If you purchased the No SIM version, you'll need to install and activate your own compatible SIM card.

Step 2: Verify the SIM Card Is Installed

Open the SIM compartment using the included TickTalk tools.

Confirm that:

  • A SIM card is present
  • The SIM card is seated properly
  • The SIM card has not shifted out of place

If the SIM card is missing, contact TickTalk Support with your order number.

Step 3: Reinstall the SIM Card

  1. Power off the watch.
  2. Remove the SIM card.
  3. Reinsert the SIM card with the chip facing down.
  4. Securely close the SIM compartment.
  5. Reinstall the SIM Lid Protector if applicable.

Step 4: Restart the Watch

  1. Power off the watch.
  2. Wait a few seconds.
  3. Power the watch back on.

After the watch restarts, check whether the SIM is detected.

Step 5: Confirm the SIM Is Activated

If you're using TickTalk Wireless, make sure the SIM has been activated.

Activation Portal: activate.myticktalk.com

If you're using your own carrier, verify that the SIM is active and supports voice, text, and data service.

Step 6: Check Signal and Airplane Mode

Confirm that:

  • Airplane Mode is turned off
  • Cellular service is available in your area
  • The watch has adequate signal coverage

Step 7: Reset the Watch

If the issue continues:

Settings > Reset

After the reset is complete, check whether the watch detects the SIM card.

When to Contact Support

If the watch still displays "Missing SIM" or "No SIM Card" after completing all steps above, please contact TickTalk Support.

Support Hours: Monday–Friday, 9:00 AM–6:00 PM PST
