Sideline – 2nd Phone Number

Get a second number with clear calls and offline texting

Sideline delivers a practical way to separate work and personal life by giving you a dedicated second number on the same device. Built by Pinger, it targets individuals who want extra privacy or professionals who prefer a distinct line without juggling another handset. Calls sound crisp, and you can place calls and send texts without an internet connection, which is a major plus when Wi-Fi is spotty.

There are some eligibility limits to note. New accounts must use a phone number from the lower 48 states and Washington, D.C., so Canadian, international, Alaska, and Hawaii numbers are not supported. You also cannot pick a Canadian or overseas area code for your new line. Account creation requires signing up and choosing a plan before you begin a one-week free trial, and your selected plan applies once the trial ends.

Sideline includes smart touches that streamline daily communication. If you miss a call, the app can automatically text a custom message to explain your availability. Voicemails are transcribed, letting you read messages when you cannot listen. A Favorites section puts frequent contacts front and center for quicker reach-outs.

User feedback points to reliability hiccups that can undercut its business-friendly pitch. Some report calls that never arrive, images that do not actually send yet look delivered, laggy media uploads, and occasional dropped calls. These issues may be frustrating if your second number handles client conversations or time-sensitive matters.

Verdict: Sideline is a strong fit if you need a clean separation between personal and professional communications, appreciate readable voicemail transcriptions, and value calling and texting without relying on data. Just weigh its regional restrictions and reported reliability problems, and make the most of the trial to see if it meets your day-to-day needs.
