Reduces Roaming Cost:

When a phone comes into roaming, then call rates changes. For international roaming , the cost increases a lot.  This is because of roaming agreements between the mobile operators and network providers changes from county to country. With the VoiP , a mobile device can use the free internet connection over WiFi.  As we know that at most of places, Airports , Hotels, etc, free wifi is available.  A voip user can easily connect the internet for voice communication.

Increased Coverage :

Cellular towards are every where.  A phone with voip capability can use the cellular tower when in range of a telecom network and WiFi network (if available) when there is no telecom cell coverage.  This enables a much broader coverage to a mobile subscriber.

Voip Disadvantages:

Voip might not be allowed at all the places. This is because of security reasons.  As voip do not uses the telecom network as like normal call.  So the local mobile operators can not keep track of calls . Which may be a major security threat.

Vopi is not beneficial for a mobile subscriber, who is allowed to use a very less mobile data or internet.
