Also happens on my mx4. Even with a stable connection it is not possible for me to receive or make calls for sure. Connection drops while dialing or when I try accept a call.
The first two days after a factory reset it was more stable, but now it's just not usable anymore. Sometimes SIM is forgotten within a few minutes.
