For optimal performance and to prevent damage, always ensure the device is fully powered off—with both external power and the internal battery disconnected—before inserting or removing the Micro-SIM card. Failure to do so could result in a damaged Micro-SIM card or the device failing to detect it.
Internal Battery Disconnection Procedure To disconnect the internal battery, remove the device enclosure carefully and separate the PCB from the casing. The internal battery is connected to the PCB using a 2-pin connector. Gently unplug the connector from the port. After inserting or replacing the SIM card, reconnect the 2-pin connector securely before reassembling the enclosure.
