Question about Huawei Watch GT 2 Elegant Edition

Unfortunately, you cannot make a phone call with this watch. It only shows you that you have a call.

Since Sandrokunz2 bought the watch, I would listen to his comment :-)
For me it was just internet research.

Correct, has a microphone according to various test reports, look here for example:
