User Reviews

Sideline provides a helpful second-line solution with a unified inbox and business-focused features, appealing for separating work and personal calls. Reviewers praise its simplicity and continuity of use. However, recurring issues include pricing increases, spam call nuisance, unreliable text/notification delivery, inconsistent call reliability, and customer support frustration. Overall it delivers core value for a second line, but cost and reliability problems appear across multiple reports.
Pros
  • Provides a true second phone line that keeps work and personal calls separated, with all calls and texts accessible in one app.
  • Intuitive, easy-to-use interface that’s straightforward to set up and use.
  • Unified inbox and cross-functionality (calls and texts in one place) that helps you manage communications efficiently.
  • Feature-rich for business use, including auto-texts to missed calls, out-of-office messages, and customizable ringers.
Cons
  • Pricing is repeatedly criticized as high and has recently increased (examples include monthly/yearly rates and notable price hikes).
  • Spam calls remain a major annoyance; spam protection is not consistently effective.
  • Notifications and text delivery are unreliable, with missed texts, missing sounds, and messages sometimes disappearing.
  • Call reliability can be inconsistent, with calls sometimes failing, not ringing, or having poor clarity.
  • Customer support is frequently described as slow or unhelpful, with AI-style responses and limited direct contact.
