I just bought a Huawei WATCH 2 4G watch. Why can't I send a text message when I connect my mobile phone?

1. In order to increase the battery life, when the watch is connected to the mobile phone via Bluetooth, the mobile network function in the watch will be automatically turned off. If you want to keep the mobile network function of the watch turned on at any time, you can set it in the settings of the watch->; Network connection-> Mobile network->; In the mobile network, change the setting of the mobile network from "Automatic" to "On".

2. If you still can't send and receive SMS after the Bluetooth connection between the mobile phone and the watch is disconnected, please confirm that your SIM card is not in arrears, and then please set-> Network connection-> Mobile network->; Check the network status and service status in the SIM card status; If the SIM card or network is abnormal, please contact the operator.
