I had the same issue. I tried 2-3 different apps (from my mobile here in TH to Europe landlines. I choosed the App "Viber". The costs are peanuts, once charged with 30US$. And made several calls since then, and still over 28US$. As usual, they all try to get as much as possible from your personal datas. As I like to check before downloading such apps, Quote AI: By default, Viber uses end-to-end encryption for private chats and calls, ensuring that the content cannot be read by third parties or the service provider. However, critics point to extensive data collection, access to the address book, and opaque server structures when compared to strict open-source messaging apps. I don't give them access to my contacts, for iPhone possible, I don't know if Android lets you make this decison. Means you have to type the first time the wished connection in yourself. Afterwards you can choose them from the list who you have contacted. P.S. Also no commission of course.
