Why can't my HUAWEI WATCH 2 watch receive incoming calls and text messages after plugging in the SIM card? Ask the master to answer!

"Mobile Network" of Huawei WATCH 2 Watch (Settings >; When network connection > mobile network > mobile network is automatic, the mobile network of the watch SIM will be automatically closed after being connected to the Bluetooth of the mobile phone. At this point, your watch number can't receive incoming calls and text messages, nor can you send text messages, but you can make phone calls.

When the watch is disconnected from the mobile phone Bluetooth, the mobile network of the watch will be automatically opened, and incoming calls and short messages can be received at this time. If you want to make a direct call, you can set the "mobile network" to on, but the watch consumes a lot of power after it is turned on.
