Sideline - 2nd Phone Number

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

Sideline is the fastest-growing phone solution for businesses, teams, entrepreneurs, freelancers, or anyone who needs a 2nd number. Why? Because Sideline is built for professionals and works anywhere your cell phone does. How? It uses your existing carrier network (not Wi-Fi). That means you never have to pay us for minutes. With Sideline, carrying two cellphones and paying for desk phones will soon be a thing of the past.

Still on the fence? Check out this lovely feature list:

AREA CODE SELECTOR – Local or not, you can select the area code of your 2nd number.

NUMBER PORTING – Already have a 2nd number? Bring it with. Porting lets you transfer existing numbers to Sideline from another device or landline.

CARRIER RELIABILITY – Most calling apps only work over Wi-Fi. Unlike them, Sideline uses your existing cellular network. This gives you the same great call quality you get from your regular number.

TEXTING & CALLING – Texting is free and unlimited. Calling works with your carrier plan so your minutes (which are probably unlimited) get shared between your two numbers.

CUSTOM VOICEMAIL – Greet callers with a voicemail for your Sideline Number. You’ll sound more professional and keep your work and personal voicemails separate.

HOW IT ALL WORKS – Your two numbers simply live in different apps. Separate caller IDs, notifications, and ringtones make it clear who’s contacting you. And on which number.

PRIVACY – Personal phone numbers are part of your mobile identity. Probably for life. Like a social security number, you shouldn’t give it out to everyone. A spare phone number can really come in handy.

VOICEMAIL FORWARDING – On nights, weekends, or holidays, silence Sideline and send callers directly to voicemail. You can even set up multiple voicemails or auto-text replies for any circumstance.

VERY OPTIONAL UPGRADES – We think everyone should have two numbers. So Sideline is free for everyone. A 2nd number, calling, texting, voicemail—the whole thing. But as businesses grow, sometimes extra functionality is nice to have. That’s why we offer the following bells & whistles:

REMOVE ADS – Yep, just like it sounds. We show ads to keep Sideline free. But you can remove them. *In App Purchase Required

VOICEMAIL TO TEXT – Get your voicemails transcribed and conveniently read them as a text message. *In App Purchase Required

SALESFORCE INTEGRATION – Access your Salesforce contacts and leads with Sideline. Then log calls and business communication so you can always be closin’. *In App Purchase Required

SIDELINE FOR ENTERPRISE – Turn employee phones into your company phone system. With an Enterprise account, businesses can remotely manage multiple employee numbers. That means nobody has to carry two devices, desk phones can retire someplace warm, and personal numbers can stay personal. It’s an entire business phone system, in one simple app. Enterprise Account Required. See our website for details.

AUTO-ATTENDANT – Create a virtual receptionist to greet callers and forward them to right person, place, or department. “Press 1 for sales, 2 for support” and 3 for anything else. *Enterprise Account Required.

INTERNATIONAL CALLING – With over 165 countries supported, you can stay in touch with people all over Mother Earth. Unlimited plans are $15/ month per user. *Enterprise Account Required.

TERMS & STUFF – Subscriptions are automatically billed monthly to your iTunes Account and auto-renew. You can turn off auto-renew or manage subscriptions in your account settings. Cancellations aren't allowed during active subscription periods.

Privacy policy & terms of use:

*Data & Internet connectivity are still required for general functionality. “Using your carrier network” makes call quality more reliable than calls over VoIP or Wi-Fi.

*Calling & texting for Hawaii, Alaska & U.S. territories coming soon.

Book Writer in NY

Excellent app - Highly recommend it  Book Writer in NY  5 star

I'm an author & baker who is always meeting new people that need my number. This app allows me to keep my person number private and still have people get in touch with me on my phone. I love it and have suggested it to my friends. It's great if you have a side or home business. You're able to talk, text, talk-to-text, send photos and even create a personal voice mail greeting. I love it.
