Use a Twilio number on iPhone

Use RingOtter to call and text from the Twilio number you choose. Start by checking the outgoing number, especially when you keep personal and business numbers in the same app.

Check your setup first

If this is your first time, connect your Twilio account and review incoming routing. Confirm that your chosen number has the capability you need. Calls require voice support; text messages require SMS support.

The app plan does not include Twilio usage. A test call or text may incur a provider charge.

Send a text from the right number

Open Inbox and start a new message, or open an existing conversation. Check the outgoing Twilio number before sending. Enter the recipient’s number with the correct country, write your message, and send it.

When you reply in an existing conversation, confirm the conversation’s number identity. A customer who contacted one business number should receive the reply from that same number.

If the recipient does not get the text, check the message status and the delivery troubleshooting steps. Avoid repeatedly sending the same message while investigating.

Make a call

Open Calls and start a new call. Choose the outgoing Twilio number, then enter the destination or choose a contact. Check the country and complete number before calling.

Microphone access and account calling setup must be ready on this iPhone. If the other person cannot hear you, check microphone permission and your audio route. If the call is rejected, check the app’s error and the matching Twilio call record.

Receive the reply or callback

Incoming calls and live messages depend on the number’s routing as well as this iPhone’s setup. Outgoing success alone does not prove that incoming routing is enabled.

Call your Twilio number from another phone you control and reply to your test text. If the call never rings or the reply does not appear, follow incoming-call help or message help.

Find the conversation later

Use Inbox search or its number filter to narrow the conversations you see. Search operates on loaded messages; load older messages if you need earlier history.

When several numbers are connected, give each number a recognizable name so the outgoing identity is easier to check.
