Call abroad at pay-as-you-go rates from a second phone number that lives inside your iPhone — no contract, no monthly minimum, and every call shows exactly what it cost. Pick a number in the United States or Canada and use it for calls and texts without carrying another device or swapping SIM cards. It is a practical fit for freelancers, small businesses, marketplace listings, and anyone who wants work calls kept separate from personal ones. GET A NUMBER Browse available US and Canada numbers, narrow the search by city or area code, and activate one in a couple of taps. Local and toll-free numbers are both available. The same number handles both calls and messages, so there is nothing else to configure afterwards. Choose how long you keep it — 7 days, 30 days, 90 days or a year — and cancel at any time. CALL Dial over Wi-Fi or mobile data. Calls run through the standard iOS call screen, so mute, speaker, and the lock screen behave the way you already expect them to. If you hold more than one number, pick which one shows as your caller ID before you dial. TEXT Receive SMS on your TwinPhone number. Conversations stay grouped by contact, and the inbox can be filtered by number once you have a few. PAY AS YOU GO Calls and messages draw from a prepaid balance you top up in the app through the App Store. Top-ups come in a few fixed amounts, and the credit lands on your balance as soon as the purchase clears. No contract and no monthly minimum. Every call is logged with its duration and what it actually cost, so your balance never moves without you being able to see why. ALSO INSIDE - Sign in with Apple, or with a one-time code sent to your email - Call history per number, with cost and status - Light, dark, or follow your system appearance - Delete your account from Settings, entirely in the app - 16 app languages, following your iPhone or chosen in Settings GOOD TO KNOW TwinPhone works alongside your mobile carrier rather than replacing it, and it cannot be used to reach emergency services such as 911 or 112. Calling to some destinations is not available. An internet connection is required. SUBSCRIPTION TERMS A phone number is an auto-renewing subscription, sold in 7-day, 30-day, 90-day and 1-year lengths. The length and the price are shown in the app before you confirm, and payment is charged to your App Store account. The subscription renews automatically unless it is turned off at least 24 hours before the end of the current period; your account is charged for renewal within 24 hours of the period ending. You can manage or cancel a subscription in your App Store account settings at any time. Calling credit is a separate one-time purchase and is not a subscription.
