SMS use cases: what to build with a gateway on your own number
Nine jobs SMS does well when the sender is an Android phone with your own SIM: passcodes, reminders, order updates, alerts, inbound messages, a support inbox, announcements, lead follow-up and agent notifications. Each page gives the flow in a few steps, a runnable send or receive snippet, a message template where one fits, the consent rules that apply, and the limits of sending from one phone.

What all of these have in common
The message comes from a real number on a SIM, so recipients can reply and the cost is the SIM plan plus a flat textbee plan rather than a fee per message. One phone sends roughly 10 to 15 messages a minute, so a large blast takes time to drain. Carriers can filter bulk patterns on consumer SIMs. Marketing messages still need consent from the recipient under the local rules.
