To get SMS delivered in commercial applications (for example for confirmation codes or transaction numbers etc.) you do not send a message from one phone to another, but instead you have a messaging provider like Brevo who gets messages delivered to the mobile phone providers directly. This avoids interoperability issues. And yes, this is not for free of course. -- Arno Welzel https://arnowelzel.de
