What Is Sideline?

Sideline is a business communication and telephony solution that provides a dedicated second phone number for professionals and small businesses. Users can make and receive calls, send texts, manage voicemail, and communicate with customers without sharing a personal phone number. The platform also supports web texting, auto-replies, caller ID, spam filtering, and shared Team Numbers for small teams. Standard calling runs on the mobile carrier network, while optional VoIP calling is available where cellular coverage is limited.

What Is Sideline Best For?

Sideline is best known for its 2nd Number feature. When one number handles both personal and public contact, there is no way to separate who should have the real number from who should not. Users can choose a local area code and pick a memorable number from available options. An existing number from another device or landline can also be ported to the account at no additional cost.

How Much Does Sideline Cost?

Sideline pricing starts at $14.49/month for a monthly plan, which includes a dedicated second phone number and business communication features such as calling and texting. Sideline offers also extended subscription options, both of which require the full amount to be payable upfront:

Half Yearly (6 months): $69.99
Yearly (12 months): $129.99

Subscription taxes may apply depending on the state associated with the user’s iTunes or Google Play account.

In addition to the base subscription costs, organizations should account for the following potential expenses:

Taxes: Approximately $10–$25/year depending on the applicable sales, VAT, or other taxes
Carrier Charges: $0–$120+/year depending on the user's existing mobile plan, cellular voice usage, SMS/data allowances, and carrier policies
Port-Out: $19.99 one-time fee may apply when porting out a Sideline-selected number
Implementation And Setup: $0–$100 for account setup, number configuration, voicemail, and workflow customization

Reviewers generally consider Sideline affordable for a second business number on a single device. Some users, particularly small businesses and non-profits, flag past price increases and the removal of the free plan as factors that affect long-term value.

For accurate pricing based on your organization's needs, it's recommended to request a custom Sideline price estimate.

Disclaimer: The pricing is subject to change.

Sideline Integrations

The vendor has not provided details about third-party integrations for this software. Users can, however, import contacts from sources such as Google Contacts, Salesforce, and Zoho using VCF or CSV files.

How Does Sideline Work?

Here's how you can get started with Sideline after downloading the app:

Download the Sideline app on your iPhone or Android device

Sideline Use Cases

Based on our analysis of user reviews and Sideline features, we have identified key scenarios where the platform is a strong fit for individuals and professionals:

Freelancers Managing Work And Personal Communication Through The Same Number

A freelancer who uses their personal number for clients has no clear line between work calls and personal ones. The same number receives client texts, follow-ups, and spam alongside everything else. Sideline gives each line its own contacts, voicemail, and notifications so work communication stays in one place. The setup takes a few minutes and works on the existing carrier without additional hardware.

Online Sellers Who List A Personal Number On Marketplace Platforms

Selling through platforms like Facebook Marketplace, Craigslist, or eBay often requires a visible contact number for buyers to reach out directly. Using a personal number means that number stays in a stranger's phone long after the transaction ends, with no way to control follow-up contact or limit exposure once it has been shared publicly. Sideline provides a dedicated number for listings that keeps the personal line out of the exchange. Once a sale is complete, the number continues to handle new inquiries without any connection to personal contact details.

Small Business Owners Who Need To Manage Client Texts From A Laptop Without Carrying Two Phones

Managing client texts from a phone all day makes it hard to keep up with longer conversations. A separate business messaging account adds another login to manage on top of everything else. Sideline's web messaging portal lets users text from their second number on a laptop without switching devices. Reviewers who chose Sideline over alternatives describe desktop texting as one of the features that made the switch worthwhile.

Non-Profits And Community Organizations That Need A Contact Line Without An Enterprise Phone System

A non-profit that needs a public contact number often cannot justify the cost of a full business phone system. Most enterprise phone tools are priced for larger teams and include features the organization will never use. Sideline provides a second number at a lower monthly rate than most business phone platforms, with texting and calling included. User feedback suggests that the price point can be a consideration that works in the platform's favor for budget-conscious organizations.

Is Sideline Right For You?

Sideline suits freelancers, small business owners, online sellers, and independent professionals who need a dedicated work line without carrying a second device or signing up for a separate phone plan.

Sideline is developed by Pinger Inc., which also operates TextFree and Index. The latest App Store updates have focused on speed and reliability improvements alongside minor performance fixes. Standard calling runs on the carrier network rather than internet connectivity, which maintains call quality in areas with limited Wi-Fi access.

The platform may be less suited to larger teams that need advanced call routing, shared inboxes across multiple users, or enterprise-grade phone infrastructure. Organizations that require HIPAA-compliant communication tools should verify Sideline's current certification status before committing.

Sideline Features

Work Texting

The Work Texting inbox is tied exclusively to the Sideline number and isolated from the device's personal messaging app. It supports unlimited SMS and MMS, and a web portal allows texting from a laptop or desktop browser without switching devices.

See How It Works

Auto-Reply

This automated response tool sends configurable text replies when calls or messages to the Sideline number go unanswered. Separate replies can be set for inbound calls, inbound texts, or specific situations, with each supporting custom text and an optional image or logo.

See How It Works

Number Porting

An existing phone number from another device, carrier, or landline can be transferred to Sideline with the original digits preserved. Contacts do not need to be notified of a change, and porting is available at no additional cost.

See How It Works

Group Messaging

Multi-participant conversations run through the Sideline number as a single shared thread. All replies from each contact appear in the same place, without creating separate one-to-one conversations for individual participants.

See How It Works

Separate Caller ID

Each outbound call from the Sideline number displays a distinct caller identity, separate from the personal line on the same device. Recipients see the Sideline name and number rather than the personal number, regardless of which line initiates contact.

See How It Works

Voicemail To Text

Voice messages left on the Sideline number are transcribed automatically and delivered alongside the original audio recording. Users can read the transcription or listen to the message depending on their preference or context.

“weak support”

Pros

Getting started is very quick which works well if you are a single user and only need something basic. We had been using their enterprise option before they started phasing it out. The setup itself is very simple, with no TCR application to deal with and no extra management needed, it just runs.

Cons

The support is pretty disappointing since there is no way to call anyone directly. Everything has to go through chat support. On top of that an account can get blocked at random with no warning if they think you are spam even when you are not and they do not notify you when it happens. That means you are left checking with clients to figure out how long messages may have been missed. It also lacks important features such as call transferring, recording and even the ability to download voicemails.
