I'm looking for recommendations on getting a US phone number on my Japanese cell phone, via VOIP. I currently have such a thing with Skype, but their app and feature design are gratuitously stupid... just amazingly dumb.
My needs are simple... I pay a fee to get a US-based phone number, and when someone dials that number, it rings on an app on my iPhone. And using that same app, I can dial out. Voice messages a bonus.
I'd like to use Vonage's app (I've been a normal Vonage customer for a decade), but it doesn't work with Japanese phones.
