Are you reaching a Twilio^® plateau?

Bandwidth believes standard support should always be included. Instead of tacking on an additional fee for support, like Twilio, Bandwidth brings white glove support to every customer with pride, and we have some of the industry’s greatest minds on staff to help our customers with innovative new ideas and navigating industry guidelines. Need even more dedicated support? We have premium options available on top of our best-in-class signature support.

Because Bandwidth owns our own nationwide VoIP network and is a Tier 1 messaging aggregator, we have direct connections to carriers and pricing that Twilio can’t match, which can save customers up to 50%. The more calls you make and messages you send to your opted-in users, the more you save. With Bandwidth, you’re getting the advantage of owner economics. And on top of that, we provide white glove support for free to all of our customers.

Twilio often cites 90%+ message deliverability but doesn’t explain how they got you that number, often estimating the rate of delivery to the carrier only. Bandwidth goes deeper into message delivery insights to let you know if the message actually reached the end user.

Our nationwide CLEC VoIP network means we have top-notch call quality and less call transfers, meaning fewer chances for dropped calls. In fact, we have 99.996% core network uptime globally. We can also troubleshoot quality issues directly thanks to our network ownership, providing our customers with the best quality possible. Twilio is not a network owner and must pass traffic through various third-party carriers, causing more dropped calls, bad call quality, and an inability to directly troubleshoot the problems.

Yes! Bandwidth’s industry-leading phone number management application makes it easy to port your existing numbers from your current carrier to Bandwidth. Our team of dedicated porting experts will even work with you to overcome any issues and make sure the experience is as smooth and happy as possible.

We work with all types of customers. Our typical customer is looking to scale and wants the power and flexibility that comes with working with a provider that owns the network and an API platform. While Twilio is great for companies that are just starting out and need to quickly get to market, our platform offers more control and direct-to-carrier pricing that Twilio can’t.

Our dedicated team of onboarding and migration specialists are here to help you during the migration process. Our APIs align closely with Twilio’s, making the process relatively painless. You can learn more by downloading our Twilio Migration Guide.

Bandwidth’s Dynamic Number Intelligence (DNI) is an unlimited-use bundle, not a per-lookup fee. One API call returns line type, carrier name, voice and messaging provider, carrier-reported deactivation status, and Bandwidth-observed number status, all from the same request. Bandwidth continuously monitors number status across its own network, so you catch reassigned or deactivated numbers before they bounce a campaign or put your list out of compliance with carrier and CTIA policies. Twilio’s Lookup API charges per lookup and per data package, which gets expensive fast at volume and still doesn’t give you Bandwidth’s real-time, network-verified deactivation signals. With DNI, you get predictable costs, cleaner contact lists, and fewer wasted messages, backed by the network that actually owns the data.

Bandwidth owns and operates its own nationwide network, so number provisioning and porting run through direct carrier connections instead of passing through third parties. Twilio relies on network partners for its voice network, which means number orders and ports route through outside carriers, adding a layer between you and the fix when something goes wrong. That ownership also shows up in support: Bandwidth’s porting experts work the process with you end to end and troubleshoot issues directly, while Twilio customers navigating a stuck port often wait on a third-party carrier relationship that Twilio itself doesn’t control. For teams managing large or complex number inventories, that difference means fewer delays and a single point of accountability when something needs fixing fast.

The companies that best fit Bandwidth currently are growing and larger enterprises with in-house development resources that want greater control and customization ability over every aspect of your users’ experience. When out-of-the-box tools become too constraining, we’re the platform you graduate to.

We bring a carrier-grade network to the table, so the higher your throughput, the more it will make sense for you to choose Bandwidth. Since we’re our own carrier and aren’t paying a third party network mark-up fee, we’re able to give you an excellent cost per call.

Yes. Bandwidth’s owned network reaches 65+ countries, with National Operator status in 30+ where in-country regulatory know-how comes built in. You spend less time on setup with automated back-office telecom operations like porting.

The comparison holds for most of the aggregator-based CPaaS platforms (Twilio, Vonage, and others). They route your traffic through third-party carriers, adding hops, cost, and troubleshooting delay. Bandwidth owns the network and connects directly to PSTN where it matters most, so reliability, pricing, and support all trace back to one accountable source instead of a chain of vendors.

Some competitors claim network ownership too that’s worth digging deeper into. Note that an IP overlay network and a PSTN network are not the same thing.

In the US, Bandwidth is a CLEC, a Competitive Local Exchange Carrier, licensed under the Telecommunications Act of 1996. It’s a regulatory status. It requires Bandwidth to interconnect directly with the PSTN at the local exchange level, subject to FCC oversight, state level certification in every market we operate, and direct interconnection agreements with ILECs like AT&T. The same legal framework that governs how calls move across America governs how Bandwidth moves them.

The practical difference: when you place or receive a call, Bandwidth originates and terminates that call on our carrier-grade PSTN infrastructure. There’s no upstream carrier to wait on when something breaks. No aggregator sitting between your call and the network. No blind spot in the path.

Bandwidth is a Tier 1 messaging aggregator, which means we work directly with carriers to deliver messages to the consumer. As a carrier ourselves in voice, Bandwidth’s team of experts operate differently. When compliance requirements shift or carrier changes impact the way you do business, you hear it from us first, not in a mass email six weeks later. And our registration experts and knowledgeable account teams are equipped when you need to make strategic changes that impact your channel strategies. That means fewer surprises, faster decisions, and a messaging strategy you can actually plan around.
