Frequently Asked Questions

Clear answers on call forwarding, real SIM routing, and trials.

How does call forwarding work with my carrier? ▼
We use standard telecom Conditional Call Forwarding (*71). When someone calls your business number, your phone rings normally for 15 seconds. If you answer, the call is yours. If you don't answer, your carrier automatically forwards the caller to your assigned AI receptionist number. You can cancel forwarding anytime by dialing *73.
Why does this avoid carrier A2P 10DLC bans? ▼
Twilio and VoIP cloud platforms route text messages through virtual numbers, which carriers aggressively block, surcharge, and require weeks of expensive 10DLC paperwork for. Missed Call Auto SMS transmits SMS directly through your physical Android SIM card via native Android telephony APIs, appearing as authentic person-to-person (P2P) texts.
What is the 2-Way Conversational AI SMS feature? ▼
Unlike dumb auto-responders that blast a single canned message, our Conversational AI SMS engine holds an authentic back-and-forth dialogue with the customer via your real SIM. It collects job addresses, qualifies emergencies, and books appointments. Plus, our built-in Human Takeover Safeguard auto-pauses the AI for 30 minutes the second you manually reply.
How does the 3-day free trial work? ▼
You can try Missed Call Auto SMS for 3 full days completely free ($0.00 charged today). You'll receive your license key instantly. If you love it, your card will be charged $49.99 for your lifetime license on day 4. You can cancel with 1 click in your self-serve portal before day 4 with zero fees.
