"OpenPhone Review"
What do you like best about Quo?

The best thing that I have discovered about OpenPhone is that you can monitor and record all the conversations from each employee! We utilize these features to make sure that the correct information was given to the client and to protect ourselves. We also use the analytics feature to monitor if our employees are actually doing their job!

What do you dislike about Quo?

I have not found a downslide as of yet!!

What problems is Quo solving and how is that benefiting you?

OpenPhone has solved the issue we had with employees stating they made calls and sent texts when they actually didn't.

"Perfect for expats"
What do you like best about Quo?

I'm using OpenPhone to keep my US cell phone number while I'm on an expat assignment in Japan for 2-3 years. The porting process was fairly easy and only took a few days to complete. I receive phone calls and texts on the OpenPhone app and have it setup to notify me on my iPhone. As a result, I've been able to stay in touch with family and friends in the US quite easily.

What do you dislike about Quo?

I don't like that not all multi-factor authentication via text works with OpenPhone. It hasn't been too much of an issue for me, as most of those entities that don't allow it for VOIP services have another way to authenticate (such as via email), but it would be great if OpenPhone could find a way to address this as well.

What problems is Quo solving and how is that benefiting you?

Easy porting of phone number, ability to keep US phone number while living abroad, staying in contact easily with family and friends in the US, ability to make free phone calls and texts to US based phone numbers.

What do you like best about Quo?

Fast, simple, and easy to have a new number for your business. Friendly and helpful support. Extended settings: Auto record calls, business hours and voicemail can be set by your wish.

What do you dislike about Quo?

One of the services couldn't accept my phone number for any reason. Price can be cheaper.

"Excellent service for an affordable price!"
What do you like best about Quo?

OpenPhone offers similar features like most VOiP services but they always upgrades to best suit what is best for their customers at a reasonable prices.

What do you dislike about Quo?

Perhaps a support service that allow clients to call them directly for questions instead of just a by email support service. Or maybe a dedicated account manager where existing clients can air out their more urgent concerns.

What problems is Quo solving and how is that benefiting you?

I'm overseas so having a virtual US phone number enables me easy access to my US clients at economical rates.

"Very Good service and support"
What do you like best about Quo?

You can carry your phone number anywhere. It uses the internet to receive calls and it uses its app on your cellphone. Also allows you to have many phone numbers inside the app

What do you dislike about Quo?

Some Account verifications will not work such as text messages. You will need to get the phone call directly, but just for the cases that the verification allows you to.

What problems is Quo solving and how is that benefiting you?

OpenPhone will allow you to carry your phone number to any place in the world, without using the traditional phone companies.

"Very Pleased with this Service"
What do you like best about Quo?

I like the flexibility. Their desktop and mobile app allow me to use the service that best suit my comfort zone. I also love the customer service. I've reached out to them twice and each time, they have been responsive and resolved my issues. And they follow-up to make sure I'm taken care of!

What do you dislike about Quo?

Currently, there is nothing I dislike. Open Phone serves my communication needs well.

What problems is Quo solving and how is that benefiting you?

It seemed like my other provider was on automation. I was using another phone number for local calls, but I wasn’t getting calls or notifications of calls. I had several potential clients tell me that called and there was no record. I also did not want to pay the price of a kidney for phone service, but I also did not want to sacrifice quality. Open Phone solved those problems.

"UNLIMITED EVERYTHING, NO MORE TIERS!!!"
What do you like best about Quo?

The fact that this platform changes the game, and eliminates the nickel and diming for every extra feature. I have phone recording (included), Unlimited Calls (included), Unlimited Text (included), Caller ID (included), Auto Replies (included), iOs App (included), and DARK MODE (INCLUDED), I can go on and on, AND ON. For one low price? Take my MF'KN money now!!!

What do you dislike about Quo?

That the voice calls are too clear, and also too crisp and I'm sensitive to it. J/K. I had to work around and get creative with adding multiple business workspaces. I ported in 3 numbers and had to finagle with not being able to create to multiple business entities under one account. So I resolved my issue by creating separate Caller ID names for each number and separating it that way. So same workspace, but multiple numbers with it's own Caller Id name.

What problems is Quo solving and how is that benefiting you?

Price, functions and features. I was having issues with Freedom Voice, the price was cheap but you get what you pay for. I had issues where Tmobile callers were getting disconnected tones when calling into my number including my clients numbers. 800.com, I had issues with not being able to receive calls because the app went down. Sypport was not able to resolve my issue but blame it on my device and or hardware. Nextiva, is not user friendly at all. I need to hire an IT department to configure the system, not user friendly.
