  • Port your existing work number over in an easy and quick way.

Who Should Need OpenPhone Most

OpenPhone is a number of apps trusted by professionals at big companies like Deloitte, BUNGALOW, and Getaround… Therefore, it is a good choice for larger companies with a larger scale of members and more refined departments. Also, with its sophisticated features, it is built to empower every team like Sales, Support, Recruiting, E-commerce, Service-based businesses, and Real estate.

Pros and Cons

OpenPhone has a dazzling UI design both on phone and on the computer, making it very easy to use. However, for those small business owners and small teams, many features it offers are redundant, and the subscription price is higher. Therefore, it’s not fit for small business owners or self-employed.

So, whether you want to keep your personal number private or go to work with texting tools that save time, engage customers, and grow your business, Sidenote is a good choice.

Pros and Cons

Sideline offers some features that most other number apps do not have. However, the standard plan (for personal use) only allows users to practice with very limited features, of which the monthly fee is higher than other similar apps.

Google Voice

Google Voice gives you a phone number for calls, texts, and voicemails. You can use this number to make domestic and international calls both from your phone and the web browser. If you live in the US, you can choose your own number. In addition to using Google Voice for calls and messages, you can also do other regular things, such as:

  • Read voicemail transcripts in your inbox and search them like emails.
  • Create and set up your personalized voicemail greetings.
  • Make international calls at low rates.
  • Get protection from spam calls and messages.
  • Blacklist unwanted callers.
  • Screen calls before you answer.

Who Should Need Google Voice Most

Just like Sideline, Google Voice also offers two plans applying to individuals and businesses. Now it has become the preferred number app for remote teams of big companies and people who travel frequently. It is also worth noting that Google designed this app originally for IT workers.

Pros and Cons

A voice number in Google Voice works on both smartphones and the web so that you can place and receive calls from anywhere. But as a number app designed and supported by Google, its quality is not as good as other Google products, for it lacks many practical features like HD calling quality, SMS business marketing, and Incoming call notes… Another deficiency is that this app cannot make or receive international calls. If you are a fan of Google and stick to this app, Other Google workspace apps are also recommended.

Who Should Need SmartLine Most

Smartline is smart and simple to operate and very easy to use. It can be very suitable for those who do not need to use complex features for business and who only have the need to do simple work.

Pros and Cons

As its main features are just the same as Google Voice, deficiencies are also alike. In Smartline, users can only choose a US local number (which means international numbers and vanity numbers are unavailable). In addition, there are no effective features for business, so company employees seldom use them for work.


Grasshopper is a virtual phone service that gives you VoIP calling functionality and virtual fax, especially for small business owners instead of office managers. By using Grasshopper, you are able to save your dollars for your business, look more professional, separate your work and life, and do business from anywhere.

Who Should Need SmartLine Most

Grasshopper is like a replica of Google Voice, for it not only provides all of the same features the latter has, but also has a similar web design. Grasshopper helps small business owners (not office managers) to focus on their businesses.

Pros and Cons

There is no doubt that Grasshopper is the most expensive one among all of the similar number apps. It offers three plans for individual, partner, and small businesses, starting from $26/mo to $80/mo, which is overpriced as it just offers some basic business features. In short, Grasshopper is not a good choice for the majority.
