Open Phone vs Google Voice – Which Is Better?

Google Voice and Open Phone are two of the most popular VoIP services internationally. Both offer a range of features that can save you money on your phone bill, but which one is better?

Google Voice has been around for a lot longer than Open Phone, dating back to 2005. It was originally GrandCentral, created as a way for people to have one phone number that could ring all of their phones.

Open Phone was launched in 2018 by the team behind Burner, and it takes a similar approach to Google Voice. It’s designed to give you a second phone number that you can use for business or personal calls.

Both Google Voice and Open Phone offer free calls to the United States and Canada. Some key differences could make one better for you than the other.

It helps to understand the differences between Open Voice vs Google Voice to decide which service is right for you.

Open Phone vs Google Voice: What Are They & How They Work?

Open Phone

Freelancers and famous artists dread sharing their personal contact information with everyone with whom they have to interact. It goes for anyone chasing the dollar.

Open Phone is an app that provides a unique phone number for each user, allowing them to keep their personal contact information private.

When someone calls the unique number, it will ring through to the user’s actual phone. The user can then decide whether or not to answer the call. If they choose to answer, they can have a conversation just like they would on any other phone call.

If they choose not to answer, the caller will hear a message saying that the user is unavailable.

The app also allows users to send and receive text messages and multimedia messages. All of these features are available for free. There are neither adverts nor in-app purchases.

Open Phone is available now on the App Store and Google Play. Neat, huh?

Google Voice

Google Voice is a telephone service that provides call forwarding and voicemail services, text messaging, and other features. The web-based application was first launched in March 2009.

Google Voice allows users to consolidate multiple phone numbers into a single number, and receive calls and texts from any device. It also provides call forwarding, voicemail, and call blocking features. Additionally, it offers free calling within the U.S. and low-cost international calling.

Free, worldwide PC-to-PC voice calling is not exactly the scale GrandCentral offered, but it was a start. You can now use Google Voice to make free PC-to-PC calls anywhere globally.

The initial rejection on iPhone platforms prompted Google to develop the Google Voice iPhone web app, an HTML5-based interface that functions on the iPhone much like a normal app.

Inbound call forwarding to any phone was one of the features that made GrandCentral so attractive, and it’s now available in Google Voice. You can have your calls forwarded to any phone you want, including:

  • Work phone
  • Home phone
  • Mobile phone

You can even set up different rules for each number, including silently blocking spam calls.

You can now use Google Voice to send text messages to any phone, as long as the carrier supports it. You’ll save money on SMS fees, and it’s also useful when you need to send a text but don’t have your phone handy.

Not bad for a free SaaS solution. Thanks, Google!

Open Phone vs Google Voice: Similarities & Differences

The two platforms have a lot in common, but their unique designs make them suitable for varying scenarios. Which one is best for your needs depends on how you plan to use it.

Let’s explore their similarities and the nuances that set them apart.


Open Phone and Google Voice are both VoIP (Voice over Internet Protocol) services. They make calls using an internet connection instead of a cellular or landline network.

You can make unlimited local toll-free calls within the United States and Canada.

Neither service requires you to have a separate phone number. You can use your existing mobile number with Open Phone, and Google Voice lets you choose a new number or port your old number over.

Both services support toll-free MMS (Multimedia Messaging Service) and SMS (Short Message Service). You can send text messages and media files like pictures and videos with either Open Phone or Google Voice.

These two services provide for blocking unwanted callers. You can add numbers to a block list on either Open Phone or Google Voice so that they can never reach you again.

Another similarity is call recording. With either service, you have the option to record incoming and outgoing calls. It’s useful for business purposes or for saving memories of conversations with loved ones.


Now, let’s explore some of the key differences between Open Phone and Google Voice.

Open Phone is designed with privacy in mind. All calls made through the app are encrypted end-to-end. Not even the Open Phone team can listen in on your conversations.

In contrast, Google Voice is not a private platform. Google has stated they may monitor and record calls made through their service “for quality assurance purposes.”

Open Phone offers a visual voicemail feature that allows you to see a list of your voicemails and play them back without listening to them in real-time. Google Voice also has voicemail, but it works differently.

With Google Voice, you have to call into your voicemail as you would with traditional phone service.

Final Thoughts

Whether you choose Open Phone or Google Voice, you’ll be getting a quality VoIP service. The key is to decide which features are most important to you and your business.

Open Phone is the best choice if privacy is a top concern for you. Its end-to-end encryption ensures that no one, not even the Open Phone team can listen in on your calls.

Google Voice is a better choice if you need more affordable international calls, though the quality of connections could drop mid-calls. Open Phone offers better quality connections, though it’s more expensive than Google Voice.

If you’re unsure which service is right for you, we recommend trying both and seeing which one you prefer. You can always port your number over to the other service if you decide you don’t like it.
