Which Android app should I use for a free, permanent phone number that works on multiple devices?

Google Voice is a communication service that offers a free phone number for calling, texting, and voicemail management. It is particularly useful for individuals who need a consistent contact number without a monthly fee, such as frequent movers, travelers, or budget-conscious users. The app allows seamless call forwarding to linked devices, text messaging from the Google Voice number, and voicemail transcription that converts messages to text. Users can access the service through the Android app or a web browser, ensuring flexibility across platforms. Reviews indicate that many appreciate the cost savings, with some reporting thousands of dollars saved over years by avoiding traditional phone bills. For instance, one user mentioned using it since 2013 without a cell phone bill, highlighting its financial benefits. However, there are limitations to consider. Some users report occasional choppy call quality or audio issues, such as speaker problems during calls, which may affect reliability. Despite this, the app's core features—like free number provisioning, text management, and cross-device accessibility—make it a strong choice for those seeking a secondary or primary number. It is not ideal for video calls, as noted in feedback requesting video add-ons, but for voice and text communication, it performs well in most scenarios.
