To send an SMS to a contact, you must ensure that the smartwatch is correctly connected to a SIM card subscription and that the communication functions are set up via the TCL Connect app. Make sure that the contacts in the app are configured correctly and the SMS function is activated. If it still does not work, check the network connection and the SIM card.

If you need further help, I recommend consulting the user guide or the manufacturer's support pages.

Hello, have you found the solution? I have just bought the watch for my daughter. The contacts are saved in the TLC application. She can call the contacts but cannot send text or voice messages.

I have the same problem: I can't add contacts for calls only?
