Not able make conference call in Motoroal MOTO E When i tried to make a conference call in Motorola MOTO E it is not allowing.

While giving the merge call option it says "Conference call is not allowed". 

please clear my doubt  whether MOTO E supports Conference call facility or not .
That message tells you that conference calling is not allowed by your carrier; it's not that the phone doesn't support it. You need to contact your carrier to enable this feature.
