Turn any Wi-Fi network into your own private phone line. WiFi Calling - No Internet lets two phones on the same Wi-Fi talk directly to each other. No SIM card. No mobile signal. No data plan. No internet connection. Your voice never leaves the local network. HOW IT WORKS 1. Install the app on both phones. 2. Connect both to the same Wi-Fi network or hotspot. 3. Open the app. Each phone appears on the other's radar. Tap a name and call. No account. No phone number. No sign-up. Nothing to configure. WHAT YOU CAN DO - Clear voice calls over your local network - Video calls when you want to be seen - Send text messages during a call, or on their own - See everyone nearby on a live radar screen - Connect instantly by scanning a QR code - Set a display name and photo that others see - Review your call history and past conversations - Light and dark themes NO ROUTER? NO PROBLEM Turn on Personal Hotspot on one phone and let the other join it. You get the same direct calling with no router, no broadband, and no SIM in either phone. PERFECT FOR - Buildings with no mobile signal: basements, warehouses, hospitals, workshops - Farms, building sites and large properties that need a simple intercom - Homes where children or older relatives have a phone but no plan - Hotels and hostels abroad, instead of paying roaming charges - Camping and remote trips, using one phone as the hotspot - Spare phones and tablets with no SIM, turned into handsets BUILT FOR PRIVACY Calls, video and messages travel straight between the two devices across your own network. Nothing is routed through our servers, because there are no servers. Your contacts never leave your phone. There is no account to create and nothing to leak. WHAT YOU NEED - Both people need the app installed - Both devices must be on the same Wi-Fi network or hotspot - Some public and workplace networks block device-to-device traffic. If yours does, open Connect and pair the two phones by QR code instead This app connects devices to each other over Wi-Fi. It does not dial ordinary phone numbers and is not a replacement for your mobile carrier. From SCB Tech Solution.
