Features & Capabilities

Twinline gives you a second phone number for calls, texts, and voicemail, so you can keep work and personal life on one device without carrying two phones.

Your second line runs on your own Twilio account. You stay in control of your number, and Twinline gives you a clean, modern app to use it.

WHAT YOU CAN DO
• Make and receive calls from your second number
• Send and receive SMS and MMS
• Get voicemail with transcription
• Use more than one number in the same app, with each call and text attributed to the right line
• See which of your numbers an incoming call or text arrived on
• Get push notifications for incoming calls, messages, and voicemail

KEEP WORK AND PERSONAL SEPARATE
Give out your Twinline number for work, selling online, dating, or side projects, and keep your real number private. Everything stays organized in one app, apart from your personal line.

HOW IT WORKS
Twinline is bring your own carrier. You connect your own Twilio account, then bring an existing Twilio number or buy one in Twilio. Twinline points it at the app so your calls, texts, and voicemail show up here.

PRICING
Twinline is a flat annual subscription, about 36 dollars per year (about 3 dollars per month), billed once a year. Every new account starts with a 30 day free trial, and no card is required to begin.

Calls and messages are carried by your own Twilio account. Twilio bills you directly for that usage at its own rates. Twinline never marks it up and does not include it. The subscription is for the app only, and your telephony costs are separate and paid to Twilio.

WHAT YOU NEED
• A Twilio account (free to create, you pay Twilio for usage)
• A Twilio phone number
• Sending SMS to US numbers requires A2P 10DLC registration on your own Twilio account. Twinline explains this and links you out, but you complete it with Twilio.

PRIVACY
You can delete individual voicemails, or delete your whole account and its data at any time from Settings. See our privacy policy at twinline.io/privacy and how to delete data at twinline.io/delete-account.

Twinline is built for Android. iOS is planned.
