Sideline - 2nd Phone Number for iOS

Sideline is a productivity application designed to provide users with a secondary phone number for personal or business communication. This free app offers features such as high-quality audio for calls, the ability to send and receive texts without an internet connection, and a user-friendly interface. Users can sign up for a Sideline account and start with a one-week free trial before selecting a subscription plan. The app is particularly useful for those looking to separate their personal and professional communications effectively.

One of the standout features of Sideline is its ability to handle missed calls by sending customized messages to callers, thereby ensuring that important communications are not overlooked. Additionally, voice messages are automatically transcribed for convenience. However, it is important to note that Sideline only accepts numbers from the contiguous United States, limiting its usage for international users. While the app provides notable features, users have reported issues such as unreceived calls and slow upload speeds, which may affect its reliability.
