I have a new Galaxy Nexus. I'm looking for the best solution that will allow me, while overseas, to initiate calls to the US (or other countries). Research indicates that Skype is limited on mobile devices. But what works better? Fring? Google Talk? For some of the calls (to family) I can pre-load the desktop version of the software so that I'll be making calls with product specific clients at both ends. But for other calls I'll want to be able to call a phone number in the receiving country. I'll be using the service from Italy this spring and from SE Asia in the summer.
