Sending SMS programmatically, how to avoid a ban?

Question

Android

Faced a problem, there is an application that uses SMS to transfer data.
There is a release on the nose, and a friend of Google banned the application for similar functionality, they say fighting spam, etc. although there was no spam
It’s not a problem to quickly transfer sending SMS to a standard SMS manager, but group SMS are sent as mms, which will hit the user on the wallet
Actually the question is how explain to Google that this is not spam and avoid a ban?

Answer 1

a friend of Google banned the application for similar functionality, they say fighting spam, etc. although there was no spam

is there a link to the app?
Usually, you need to do a handshake in order for users to agree. Those. for these SMS to be accepted by the same application, after prior approval: the function of adding to CL/friends. Because otherwise, someone may complain about your application and they will definitely be banned.
Or a variant with a gateway SMS number, where all commands are indicated in the message itself, and then on the server, through the API, it is sent to the desired numbers.
