What is Unitel Voice? Unitel Voice is the business builder’s phone system - a complete virtual phone system you can manage from your computer or smartphone without any IT help. You get a local or toll-free business number, call routing, voicemail, and extensions so you can handle business calls like a pro. Whether you’re working from your home office, a coworking space, or your car, Unitel Voice keeps you connected and sounding professional. It’s easy to set up, simple to use, and backed by real U.S.-based support whenever you need help. No contracts, no commitments - just the tools you need to grow your business from anywhere. 2. How is Unitel Voice different than other business number & phone system apps? Unitel Voice isn’t built for big corporations with IT departments and endless budgets. It’s built for business builders - entrepreneurs who need something they can set up themselves, use from anywhere, and rely on to sound professional. There’s no complicated setup. No hardware to install. No contracts to lock you in. Just a local or toll-free number, easy call routing, and all the features you need to run your business on your terms. And if you ever need help? You get live, one-on-one support from a real person based right here in the U.S. That’s what sets Unitel Voice apart. It’s not just a phone system, it’s your business line, your customer experience, and your connection to growth. 3. How do I log in to the app? To log in, first create your employee extension. Then use your extension’s login credentials to sign in. (Note: your admin login created at signup will not work in the app.) 4. How do I ensure high call quality? For the best experience, use a strong Wi-Fi connection. If Wi-Fi isn’t available, the app uses your cellular data. Like all VoIP apps, weak Wi-Fi or poor data signal can affect call quality. 5. Is the Unitel Voice app free? Yes. The app is included free with all Unitel Voice business phone system plans. 6. Do I have to use the Unitel Voice mobile app? No. Unitel Voice can forward calls to any phone number or device (even landlines and old-school cell phones). We also offer the Unitel Voice Office plan for softphones and IP desk phones. 7. How does this app help my business? It gives you full access to your business phone system anywhere, turning your personal smartphone into your office phone - complete with the professional features of a desk phone. 8. Can everyone on my team use this app? Yes. Every user with their own employee extension can access and use the app to manage business calls. With Unitel Voice, each user has their own extension.
