S2MSP app

S2MSP is Connectivity tool that is open source under the Apache-2.0 license.

As Google strongly restricts the use of SMS permissions for applications in the Play-Store, S2MSP provides an API for third party applications to send and receive SMS to specific phone numbers via a secure SMS proxy.

S2MSP acts like a local firewall for SMS communication.

Each application that wants to send/receive SMS to a phone number can register itself on S2MSP. S2MSP asks the user for permission, whether the requesting application is allowed to send/receive SMS from and to the requested phone numbers or not.

All SMS exchanged with third party applications are strongly encrypted.

S2SMP itself requires SMS permissions (SEND_SMS and RECEIVE_SMS) from the Android system and will request these permissions upon startup. S2MSP does not need any other permissions. This ensures the integrity and security of S2MSP.

The API to integrate a third party application with S2MSP is available in Maven-Central.
