Calling & Texting

Unlike ‘cloud-based’ or ‘virtual’ phone systems, Sideline works with your carrier network. That gives you great quality, reliability, and lets you split your calling minutes between two lines.

We do this because WiFi calls can be inconsistent and data can be pricey. However, you can still toggle between networks. So with a strong WiFi signal, it’s a best-of-both-worlds situation.

For Individuals

Sideline is the go-to work number for freelancers, entrepreneurs, small start-ups or anyone who’s self employed.

But it’s also great for anyone who wants to sound more professional or keep their personal number private. On nights, weekends, or holidays, you can send callers directly to voicemail. Or program automatic text responses to cover for you when you’re busy.

For Companies

You wouldn’t let employees use personal email for work. Why let them use their personal phone number?

Sideline’s top tier subscription lets businesses assign their employees a work number. Now companies can ditch their office landlines, additional mobile devices and the idea of their employees leaving with important clients or contacts.
