My girlfriend is travelling to Spain in the near future, and I'll be staying here. I have a Moto Droid and she has the Hero, is their any apps or what not we can use to talk to each other, without running up a huge international calling bill?
this is exactly what Skype is for
what about fring? calling from a wifi hotspot
My girlfriend is in another country as well. We use Google Voice all the time . Not only for $.06/min calls but for free sms too.
