How do I install an eSIM plan in a TicWatch Pro 4G?

The procedure to register the esim on the Ticwatch is the following (tested on Huawei P30 Android 10 ):

• Make sure that the phone use the latest Mobvoi app as well the Wear OS app (currently 3.20.0-1301.561 and 2.44.0.353846678)
• Make sure that the watch is updated with the firmware PWDD.190617.059.A3
• Turn the watch on and connect to the phone by Bluetooth (it might also work with the WiFi)
• Open the Mobvoi app on the phone and select Communication Settings ( Screenshot 1 )
• Press scan the QR Code ( Screenshot 2 )
• Select Other as Telecom operator and Other as country ( Screenshot 3 ) press Next
• Then the procedure will start on the watch ( Screenshot 4 ) to download the carrier profile.
• If the procedure fails, just try again (for me it works the second time).
• After that the watch will reboot
• After the reboot enable the Mobile Data in the watch and enable Roaming
