How do I insert the SIM card and activate the device?
To insert the SIM card and activate the device, please follow these steps:
1. Choose a 2G GSM network-based Micro-SIM card (same as that for iPhone 4).
2. Make sure the device is powered off before inserting or taking off the SIM card.
3. Activate the GPRS data plan and Caller ID service on the SIM card, and ensure that the PIN code is turned off.
4. Open the SIM card slot using the provided tool.
5. Insert the SIM card into the slot according to the instruction direction.
6. Cover the SIM slot and fasten it with the xxxx to ensure waterproofing.
7. Press the Power Button for 3 - 5 seconds to power on the device. The blue and red indicator lights will turn on, and you will hear a ringtone.
Note: If there is no SIM card inside, press the Power Button 3 times to power off the device with a ringtone. If there is a SIM card inside, the device can only be powered off using the App.
