    The WATCHU has only been tested by us with the CPR Chameleon SIM – as such, we cannot guarantee any other SIM card will work with the WATCHU

    If you choose to use your own SIM it is important to ensure the plan includes VOICE minutes AND Data (minimum usage 30MB of data per month)

    If you are using you’re own SIM card for the WATCHU you will likely need to update the settings on the watch to match those of your SIM card provider

    To set the correct APN settings to the watch you will need to send an SMS text message from a mobile with the appropriate code below, the SMS should match the code EXACTLY with no spaces and be sent to the WATCHU SIM telephone number

    If the settings have been accepted by the WATCHU you will receive a SMS response reading “APN set OK”

    In the US, aside from OUR CPR CHAMELEON SIM, the only other confirmed working 2G network is T-Mobile

    If using the provided SIM and connecting for the first time does not work, or if you changed back to the included SIM, use the CPR Chameleon SIM settings
