"Disruptions and poor audio during calls"
1.5/5
What do you like best about NobelBiz Voice Carrier Network?

The NobelBiz Voice Carrier Network is not remarkable. It's unclear call quality is not allowing me to have uninterrupted conversations. It's poor how the network coverage does not ensure that I connect with clients and colleagues no matter where or when. Review collected by and hosted on G2.com.

What do you dislike about NobelBiz Voice Carrier Network?

The customer service they provide is cumbersome; they're not always available to assist with any questions or concerns I have. Another poor aspect is the pricing, which makes it a less cost effective choice for my business. Review collected by and hosted on G2.com.

"Inefficient global carrier networks"
3/5
What do you like best about NobelBiz Voice Carrier Network?

I've been using their services for 3 months now. I have encountered many issues. Their nationwide coverage is not working well. It would be better if they provided statewide options for programs. Review collected by and hosted on G2.com.

What do you dislike about NobelBiz Voice Carrier Network?

As for the dislikes about NobelBiz Voice Carrier Network, there are a couple of aspects that I find disappointing despite their claims of increased ratios and improved sales. I faced an inconvenience once when I purchased numbers for another company through their portal while trying to purchase DIDs. Review collected by and hosted on G2.com.

"Peace of Mind"
5/5
What do you like best about NobelBiz Voice Carrier Network?

We are into outbound calling, and since last year, we have been facing many issues getting our CLI blocked about every 10 or 15 minutes. Because of that, we were not getting proper connectivity. Instead, many of our prospects doubted why our CLI is showing as SPAM Likely. NobelBoz not only solved all of these issues with their LT Buckets Rotation feature but on the other hand, rarely have I come across a company that doesn't only provide what they sell but even one of the finest after-sale services. They are prompt and efficient and value their customer's experience and time. Kudos Team! Good going, and keep up the excellent work. Review collected by and hosted on G2.com.

What do you dislike about NobelBiz Voice Carrier Network?

Been working with them for the last 6-7 months, and nothing so far! Review collected by and hosted on G2.com.

The service just works. We are now able to rotate our caller ids and increase the contact ratio for our outbound programs without developing costly in-house solutions Review collected by and hosted on G2.com.

What do you dislike about NobelBiz Voice Carrier Network?

Rotation buckets are nationwide. I'd like to be able to purchase regional or state-wide buckets for smaller programs Review collected by and hosted on G2.com.

"Great quality and good service"
4.5/5
What do you like best about NobelBiz Voice Carrier Network?

Nobelbiz has great call quality. We have used them for outbound campaigns. Even though we no longer have outbound projects now, we still keep their services for day-to-day office domestic and international calls. Review collected by and hosted on G2.com.

What do you dislike about NobelBiz Voice Carrier Network?

Outbound rates have reduced a lot during the past 10 years. But our rate is still the same. Since our call volume is low, the effect is minimum, though. Review collected by and hosted on G2.com.
