Bandwidth is different.

We have a Tier 1, nationwide, all IP network that covers 94% of the population—just like the legacy carriers you’ve known for years. But unlike the legacy carriers, our support and porting experience are world-class and always included.

Big support for big business

We do things that other Tier 1 carriers can’t or won’t. We have dedicated teams of experts that specialize in onboarding, number porting, network operations, technical assistance, billing, API development and more. Our porting team is the only one of its kind in the industry. Our world-class support is one of the ways we deliver less friction and more freedom for your enterprise telephony.

Powerful phone number management

Bandwidth’s APIs and powerful number management dashboards end your support ticket nightmare. You can control how and when you migrate to the cloud: department-by-department, floor-by-floor, without disruption. With our cloud-enabled trunks and number management capabilities, you can:

  • Set up and tear down workstations in seconds
  • Trigger ports in real time
  • Eliminate downtime by pairing on premise with cloud trunking
  • Cut costs and pay for what you use
