TwoLine helps you rent a second phone number for SMS verification, account setup, and privacy. Choose a supported country, pick a rental duration, add credits, and receive SMS messages in the app. Use TwoLine when you need a separate number without exposing your personal phone number. Active rentals show the phone number, expiry time, recent SMS messages, and clear policy information before purchase. Recent messages stay in one simple inbox so you can track codes and rental activity from the same place. What you can do with TwoLine: - Rent a 2nd phone number - Receive SMS verification codes - Use a separate number for account setup - Choose supported countries and rental durations - Manage active rentals and recent SMS messages - Add TwoLine credits through in-app purchases - Review refund and credit rules before renting - Delete account data from Settings TwoLine uses app credits. Store purchases add credits to your wallet, and rentals spend credits from that wallet. Some eligible rentals may offer a short credit-back window if no SMS arrives and cancellation succeeds. Credit-back is app credit only, not a cash refund. Important: TwoLine does not guarantee that any third-party app, website, financial service, bank, crypto exchange, or regulated platform will accept a rented number. Number availability, SMS delivery speed, app acceptance, and country support can vary by option. Review the rental policy before each purchase. TwoLine is not an emergency calling service and does not support voice calls. Privacy and account control: TwoLine creates an anonymous app account so wallet balance, rentals, and inbox messages can be tied to your device session. You can delete app account data from Settings. Privacy Policy, Terms of Use, and support links are available in the app and at twoline.io.

Turn the iPhone your child already has into a simple starter phone: calling and texting, without the apps, social media, and browsing they are not ready for. No new device, no extra phone plan, no Apple ID for your kid. HOW IT WORKS - Set it up right on your child's phone in a few minutes. - Choose which apps stay allowed. Everything else is shielded. - Phone and Messages keep working so they can always reach you. - Protect it with a parent passcode so it cannot be switched off. BUILT TO BE HONEST - It tells you the moment protection ever stops, instead of failing silently. - Nothing leaves the device. No account. No tracking. No ads. - A guided walkthrough helps you turn on Apple's built-in Assistive Access for an even simpler home screen, if you want it. FREE FOREVER - The starter-phone lock, the parent passcode, and the status alerts are free. PRO - Scheduled modes like School and Bedtime, approved-contacts-only, an activity log, and multiple children. StarterPhone is a parental wellbeing tool. It limits apps using Apple's Screen Time technology; it does not collect or transmit your child's data. A determined teenager with the device can still factory-reset it, so StarterPhone is commitment help, not a guarantee. Privacy Policy: https://starterphone.vercel.app/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Pro is an auto-renewable subscription (a one-time lifetime option is also available). Your subscription renews unless cancelled at least 24 hours before the period ends; manage or cancel anytime in your App Store account settings.
