User Reviews

Users widely praise Sideline for privacy, professional call management, and affordable international calls, with travel-friendly reliability. However, repeated payment issues—such as not receiving a paid-for number and duplicate charges—and limited support contact are the main recurring complaints. Overall, it’s strong for privacy-conscious professionals who need a second, affordable line, but checkout and refund processes should be improved.
Pros
  • Strong privacy and security: keeps personal information private and separates work/personal numbers.
  • Professional call management: dedicated lines help manage clients and present a polished image.
  • Affordable international calling: low-cost rates make staying connected abroad easy.
  • Reliable audio quality and connection: clear calls even in noisy environments and across devices.
  • All-in-one device: centralizes work and personal lines, simplifying switching between them.
Cons
  • Payment processing issues: paying for a number but not receiving it.
  • Payment-related errors: being charged twice or stuck in a pay loop.
  • Customer support accessibility: difficulties contacting support or resolving payment problems.

A second phone line on your iPhone doesn't have to mean buying another SIM card or carrying a second device. This app lets you manage work and personal calls separately while keeping your real number hidden, and its low-cost calling to the US and Canada makes staying connected both simple and affordable.
