Updated: Feb 14

Learn how to move your landline calls to a cell phone in three easy steps.

It's 2021 and it's time to say goodbye to your landline.

You want to get rid of your landline hardware while keeping your number. That makes sense: you've had the number for decades, it's registered in multiple places, and the convenience of a cell phone is hard to beat. You might also be moving or canceling your bundled service and don't want to lose your number.

Consolidating your landline doesn’t have to be a total headache. In fact, moving your number to a cell phone is easier than it sounds, and can save you hundreds a year. Let's get started.

In this blog post, we will walk through the three steps to keeping your landline number.

  • Step 1: Choose an option for keeping your landline number,

  • Step 2: Check if your number is eligible to be transferred,

  • Step 3: Transfer before your cancel

Step 1: Choose an Option for Keeping Your Number

Technology has made landlines redundant, but saving your landline number is still a challenging problem. Some say transferring is impossible, but by the end of this article, you’ll be helping the skeptics move their landline numbers too.

There are two options for transferring a landline number to a cell phone.

  1. Sign up for a Wireless plan: Sign up for a wireless plan with any cell phone carrier, and have that carrier port the landline number onto a new cell phone.

  2. Sign up for a Call Forwarding plan: Simply move the number to a service that offers Call Forwarding, and forward inbound calls to a cell phone you already use.

Let’s talk about the differences between these two options.

Option 1: Sign up for a Wireless Plan (~$40/month)

Most of the major carriers (AT&T, T-Mobile, Verizon, and Sprint) will let you move your landline number onto a cell phone with their cellular plans.

A wireless plan is an excellent route if you need your landline number to be on a unique separate cell phone. Still, it’s also quite expensive and requires that you buy a completely different cell phone from the one you already have.


  • Great if you need your landline number to be on a unique cell phone.

  • Great if you don’t already have a cell phone. You can just make your landline number your cell phone!


  • Expensive, standard cellular plans can range from $30-$70 a month, depending on your usage needs.

  • Difficult to setup. You usually have to switch at a retail location.

  • Requires you carry around another cell phone if you already have one.

Best Carriers

  • AT&T

  • T-Mobile.

Option 2: Sign up for a Call Forwarding Plan ($11/month)

Sometimes receiving calls from your landline number is enough. With Call Forwarding, you can do precisely that.

Call Forwarding is a service that lets you store your landline number digitally and then have all calls forwarded to any cell phone number. That means you can receive your landline calls right on your existing cell phone, without having to get a new phone or cellular plan.

The cost for Call Forwarding can vary, but in most cases, it is cheaper than your current landline service. To learn more about call forwarding, visit NumberDock.


  • Cheaper than a wireless plan.

  • Easy to setup

  • Does not require a new cell phone - all calls forwarded to your existing cell phone.

  • Transfer your number online in minutes—no visit to the retail store.


  • You can’t make outbound calls from your landline number.

  • Your landline and cell phone voicemail become the same.

  • NumberDock

  • NumberBarn

Step 2: Check if Your Landline Number is Eligible to be Transferred

Since most landline providers don’t provide wireless service, you will likely need to move your number away from your current service provider. Unfortunately, not all landline numbers are eligible to be moved to a new provider.

Luckily, we can check if your number is eligible. Use the secure and private form to run an eligibility check on your landline number. Please note, your information is secure, per our privacy policy.

What does “Porting” mean?

Porting is just an industry term for moving a telephone number from one carrier

to another. You may see “transfer” and “ported” used interchangeably.

Step 3: Transfer Before You Cancel

First, let’s just talk about why it’s essential to transfer your landline number to a new provider before canceling with your current one.

At NumberDock, we handle thousands of landline numbers. Nearly every day, we get folks asking us if they can move their number after they canceled service with their old landline provider. 99% of the time, we cannot help them because their carrier already sold their number to someone else.

No matter who you end up using, make sure you transfer your number before you cancel service with your existing service provider.

NumberDock is proud to offer the most affordable and secure way for folks to keep their home or business landline number.

Our streamlined signup makes it easy to move your number in minutes - you can even schedule it for weeks in advance. Learn more about how we can help you transfer and keep your landline number here.
