I'm looking for an iOS and android app (preferable) or iOS app and computer program that will let me make international calls or texts for free and without having me sign all of my personal information over. All of the "top rated" apps want access to a variety of information I'm not really willing to part with. I was hoping someone here had one they recommended. Calling function not actually needed, I just assume it would be packaged in. Just need to be able to message / text. Thanks.
