Disruptions and poor audio during calls **Rating:** 1.5/5.0 stars **Reviewed by:** Frances H. | Consultant, Architecture & Planning, Small-Business (50 or fewer emp.) **Reviewed Date:** January 22, 2024 **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. **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. **What problems is NobelBiz Voice Carrier Network solving and how is that benefiting you?** NobelBiz Voice Carrier Network lacks transparency when it comes to pricing. It is frustrating not having an understanding of the costs and fees associated with their services. There have been instances where their customer support was slow in responding making it difficult to get assistance when needed. ### 2. Inefficient global carrier networks **Rating:** 3.0/5.0 stars **Reviewed by:** Rose S. | Computer Applications And Software Engineer, Telecommunications, Small-Business (50 or fewer emp.) **Reviewed Date:** January 06, 2024 **What do you like best about NobelBiz Voice Carrier Network?** Ive been using their services for 3 r months now. I have encountered many issues. Their nationwide coverage is not working well. It would be better if they provided state wide options for programs. **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. **What problems is NobelBiz Voice Carrier Network solving and how is that benefiting you?** Some customers have expressed concerns regarding the reliability and quality of the service due to VoIP reductions. Businesses with departments or branches find that the corporate number provided is not sufficient. ### 3. Peace of Mind **Rating:** 5.0/5.0 stars **Reviewed by:** Ahfaz K. | IT Lead, Small-Business (50 or fewer emp.) **Reviewed Date:** November 02, 2022 **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. **What do you dislike about NobelBiz Voice Carrier Network?** Been working with them for the last 6-7 months, and nothing so far! **What problems is NobelBiz Voice Carrier Network solving and how is that benefiting you?** They helped us get more connect ratio which helped my rep talk to more people and, on the other hand, reduced the VoIP cost. ### 4.
