2-way: sending & receiving
To engage in 2-way SMS communication, i.e., both sending messages to customers and receiving replies from customers, you require a dedicated number.
You can purchase a long number or a short code from My Workspace --> SMS and link it to the 2-way SMS integration.
Numbers can also be purchased as part of the 2-way SMS setup wizard.
NOTE: if you plan on using a US Long Number, please refer to 10DLC section of this guide
