We are working on a feature that requires the usage of SMS. For that we've already enable the SMS policy, and test sending SMS to the SIM through the website and emnify API with success. We have some doubts regarding the source of the SMS. I've tried sending SMS from my mobile phone and is possible, this means that we need to filter the receive SMS by sender, but the "shortID" is possible to "fake". Is there a possibility to add a whitelist on emnify API which let us add valid senders? We intend to use only emnify API to send SMS, and reject any other message, should not be sent. Is possible have this type of control with emnify under policy configurations? Regards,
