Businessman using phone and laptop.

Adding a business line to your cell phone is useful when you want to keep your business calls separate from your personal calls — and it’s a very simple process. Read on to learn why you should get a business line for your cell phone and how to do it.

Why Add a Business Line to Your Cell Phone?

The benefits of having a business line on your cell phone are numerous, the main one being that your work number will be separate from your personal one. You can set up call forwarding so that you never miss a call while you're away from the office, or you can turn the ringer off when you're working late hours.

Some additional benefits include:

  • One phone for business and personal use
  • Separate business contacts from personal contacts
  • If your phone dies, you can forward important business contacts to a new device
  • Manage SMS/text messages
  • Keep your personal phone number private
  • Know when a business call is ringing in to answer professionally for your business/work
  • A great solution for occupational emergencies (e.g., on-call doctors, nurses, etc.) 
  • Work from anywhere, anytime

Adding a Business Line to Your Cell Phone

Adding a business line to your cell phone can be done in different ways, including: 

  • Using a Business Phone Service Provider
  • Adding a Business Line Through a Mobile App
  • Forwarding a Business Line to Your Cell Phone

The best option for your business will depend on what type of plan you have and what kind of phone you have.

Adding a Business Line Using a Mobile App

There are many mobile apps that make it possible to add a business line to your cell phone. Google Voice, for example, makes it possible to add a separate number that will ring into your cell phone. These extra numbers are relatively inexpensive and can be forwarded to any number or used to collect digital voice mail when you can’t take calls.

Adding a Google Voice business number only requires a few steps:

  1. Get a Google Workspace account
  2. Visit
  3. Select “For business”
  4. Select “Get started”
  5. Choose a pricing plan

Note: You can manage forwarding and call management online through Google Voice’s website. Just log in to your Google Voice account and see who calls, check voicemail, even receive SMS/text messages.

There are many other mobile apps that do the same thing. By searching online, you can find other options besides Google Voice.

Forwarding a Business Line to Your Cell Phone

From a standard business phone or office phone, you can set up call forwarding to where incoming calls will be forwarded to your personal cell phone. Setting up call forwarding will let you receive calls when you’re away from the office. This can be useful when you’re traveling for work, working in the field, or when you’re on-call during an emergency.

From your office landline, follow these steps:

  1. Dial *72 on the landline phone
  2. Dial your cell phone number
  3. Press #

Tip: When you return to the office, you can turn off call forwarding by dialing *73 on your business landline and then waiting for the phone to hang up. You’ll now be able to receive calls again on your office phone until you reactivate call forwarding in the future.

Should I Add a Business Line to My Cell Phone?

Adding a business line to your cell phone is worth considering if you’re tied to your work or own a business. A business phone number not only brings more professionalism to your business but also makes it easier to manage your business calls from your personal calls.

Given that adding a business line to your cell phone is an easy, low-cost option for managing your business better, helping you to grow your business faster, we safely recommend it for most businesses.
