Going to an Island off Malysia where the owner tells me only the Digi network has coverage. Tell me, if I purchase the Int Roaming Travel Pack will that automatically connect to that network on the island or will I have configure it to?
You can do it manually or automatically, this is handled in the settings menu of your phone. Look for network settings and there should be the option to automatically find a network, or select your own. Once connected, you'll get an SMS from Optus to confirm you are roaming overseas.
