Privacy Cell is a small app that displays the cell phone protocol information. At the time of this writing, many cell phone networks are switching from 4G (4th Generation) to 5G networks. The 5G network protocols were specifically designed to protect against some of the known insecurities of the older protocols, including those that allowed stingrays (IMSI catchers) to perform man-in-the-middle attacks on cell phone networks. To ease deployment and backwards compatibility, 4G and 5G networks can run together in what is known as 5G NR (New Radio) NSA (Non-Standalone) mode. This uses the 4G network for the control channel and the 5G network for the data communication. However, 5G NR NSA does not provide protection against stingrays. Android has access to all the information it needs to know if it is connected to a 5G NR NSA or a 5G NR SA (Standalone) network, but it doesn’t display that information to the user. The purpose of Privacy Cell is to make that information easy to access. Privacy Cell can also warn you when you are connected to antiquated 2G and 3G networks.

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.

You can also tell SMS Filter to delete incoming messages, in which case it will happily do so for you. To do this, just turn off the 'Save messages' preference.
