Can you send and receive text messages from multiple phone numbers in RingCentral app?

Im not sure what your question is...your post is more of a statement. But you are correct. You will only be able to send/receive texts on the number you are logged into. Think of each number like a separate cell phone. You might own two cell phones, each with a separate phone number, and just as you can only send/receive texts from each phone separately it is the same with your RingCentral numbers.
