Onestyle Opal mobile desk phone with WiFi, dual-SIM suitable for seniors. Large-button phone (Wi-Fi) – A home phone that makes you feel safe at home: Safety is our top priority. When we developed our Opal desk phone, we wanted to ensure that you feel protected. Our Opal desk phone features an SOS emergency call setting that can be activated by pressing the button three times in quick succession. This way, you can be sure that you will get the help you need when you need it most. Large buttons help you dial with confidence. In designing the Opal desk phone, we considered the needs of older adults. Whether you have a visual impairment or find it difficult to press the buttons on standard phones, our Opal desk phone with large buttons for seniors gives you the opportunity to stay connected. With the EasyCall feature, your most important contacts are just a button press away. We all have those special people we stay in touch with more than anyone else. Siblings, children, grandchildren, and friends – it’s important to keep in contact. With our user-friendly Easy Call feature (speed dial), you can save the two contacts you speak to most often, making it easy to call them. No more searching through your contact list for their phone numbers! Easy text messaging. We don’t always want to have a conversation; sometimes we just want to convey information. That’s the beauty of text messaging. But when you want to send text messages, you may find that your mobile phone is too small to see the display or press the buttons. Fortunately, with our Opal desk phone for home, you can comfortably send text messages to friends and family without any hassle.
