# FAQs

<Accordion title="Do I need a Solvea business number before using the app?">
  Yes. Calling and SMS features need an active Solvea business number. You can still log in and review the workspace, but real customer calls and texts need a number.
</Accordion>

<Accordion title="Why am I not receiving calls on iPhone?">
  Check the workspace, business number, online status, notification permission, calling permission, subscription or trial state, and AI answer rules.
</Accordion>

<Accordion title="Why does SMS fail?">
  Check recipient format, SMS-enabled number, Trust Center verification, available credits, and message content. Try a short plain-text test first.
</Accordion>

<Accordion title="Why is the AI summary or transcript missing?">
  Wait a short time after the call ends, then refresh the thread. Longer calls and translation calls may need more processing time.
</Accordion>

<Accordion title="Can I change the AI voice later?">
  Yes. Open AI Receptionist settings, preview another voice, save it, and run a test before relying on it with customers.
</Accordion>

<Accordion title="Where do I manage credits and subscription?">
  Use the Subscription, Plan, or Usage area shown in the app. The current billing page is the source of truth for limits, credits, and prices.
