how often is a WTA players allowed to call for their coach?

Is it limited?

Thanks in advance

I am not 100% sure, but I don't think there is a limit for calling the coach.
Just like medical timeout, I don't think there is a limit too.

That's something i don't understand from WTA. They loses few points and "Coach, come hold by the hand please!" Are they seriously that fkin helpless?
