International calling to and from mobile and VoIP phones

Which country am I supposed to call?

When dialing to a mobile phone, dial based on calling to where the phone is registered. When dialing from a mobile phone, dial based on where you are physically located.

When dialing to or from a VoIP phone, always dial based on where the phone is registered.

What are the costs involved?

On top of local charges, there are three possible charges involved in international calling:

The charge for the international call itself: the cost involved in placing an international call between two countries

The charge for a mobile receiving the call while in another country: If a mobile phone user receives a call while in another country, they will likely be charged a romaing fee for connecting the call through their home country as well

The charge for a mobile user for placing a call while in another country: If a mobile user places a call from another country, they will likely be charged a roaming fee for placing that call through a foreign phone network.

VoIP phone systems incur costs for internet access, however not for telephone roaming costs. As VoIP uses internet access, mobile phone users who are also using a VoIP phone service should be aware that mobile internet access in another country can be very costly.
