A 2nd number for your smartphone—that’s your Sideline.

Sideline is the fastest-growing phone solution for businesses, teams, entrepreneurs, freelancers, and anyone who needs a 2nd number. Your second number comes with all the features of a regular phone number such as calling, texting, voicemail, and more. On top of that, everything works with your existing carrier network (instead of Wi-Fi), making Sideline the most reliable and highly-rated phone app out there.

The Sideline Subscription gets you unlimited access to all of the great calling, texting, and voicemail features with premium support. ($9.99/month or $99.99/year In-App Purchase Required)

WHY SIDELINE? – With Sideline, there’s no need to carry two cell phones, stay tied to a landline, or use your personal number for work.
