How am I charged for voice mail calls while roaming internationally?
A. Voice mail calls are charged the same as calls to the US. With a GSM phone, incoming calls that try to ring your phone but are not answered, are normally charged as an international roaming incoming call to your device, even if the caller does not leave a message. You may also incur a charge for and outbound call back to your home voice mail system. If your device is turned off or in flight mode, the network does not try to deliver the call to you in a foreign country, so there are no international roaming charges.
