Calls keep disconnecting after 2 seconds

[AC Question]

Hi,
My Lenovo P700 keeps disconnecting calls after 2 seconds. Can you assist me solve this issue?

Welcome to Android Central! Does that happen regardless of using a wired headset or not? Some wired headsets can have a plug that isn't quite compatible, so it might be sending false signals to the phone to hang up. Also, have you discussed this with your carrier, in case it's a problem with your SIM?

I second B. Diddy's suggestion to contact your carrier and get a new SIM.

I've had connectivity issues in the past, and those were solved by getting a new SIM from my carrier.

This is same problem with my phone.
And my phone screen was broken.
So i decide to buy a new one.
