How to make a conference call over GSM

In a regular Android watch, while talking to someone using the GSM network, you can add another call and merge them. I don’t see such an option in the Android smart watch with the ver. 7.1.1. Any ideas?

have you tried with another phone app?

I tried a couple, none of them supported this future.

True Phone does that. I figured it out:-). One should use this app in full circle screen mode. Otherwise, add call button is overlain by the caller id.


I think it’s this one?
Thanks for sharing your found.:handshake:

Yes. That is the one. You are welcome.
