textPlus positions itself as a comprehensive communication solution that enables users to obtain a secondary phone number without requiring traditional cellular service. The Android application leverages VoIP technology to facilitate free unlimited texting to US numbers and affordable international calling, serving as both a primary communication tool for budget-conscious users and a supplementary number for privacy-conscious professionals. The core functionality centers around providing a fully functional US phone number that supports SMS, MMS, and voice calls through data connectivity. Users can send unlimited text messages to any US number without carrier restrictions, while international calls are available at competitive rates. The app integrates with existing contacts and supports group messaging, picture messaging, and voicemail features. Notably, the service operates independently of cellular networks, functioning exclusively through Wi-Fi or mobile data connections. User experience is characterized by a straightforward interface that mirrors traditional messaging apps, lowering the learning curve for new adopters. The design prioritizes accessibility with clear navigation between messaging, calling, and contacts sections. Real-world usage patterns indicate the app serves multiple scenarios: travelers avoiding international roaming fees, small businesses maintaining separate customer communication lines, and individuals seeking privacy in online transactions without disclosing primary numbers. User feedback trends reveal strong satisfaction with core functionality, though some operational concerns emerge. Multiple reviews from July 2025, including those from Julius Owens and Paul Sheppard, consistently praise the app's reliability and cost-free messaging capabilities. Owens specifically notes excellent calling quality and reliability for family communication, while simultaneously highlighting account suspension issues affecting some users. Sheppard's repeated endorsements emphasize long-term satisfaction with the service's comprehensive feature set. The application demonstrates significant strengths in cost-free domestic communication and flexible number management, though limitations include dependency on stable internet connectivity and reported account moderation practices. Ideal use cases include international travelers, privacy-conscious users, small business operators, and individuals seeking to maintain separation between personal and professional communications without additional hardware costs.
