It's a split decision.
Pick Bandwidth if you need programmable voice/SMS, direct-carrier connectivity, SIP trunking or emergency communications. Its pricing lists per-message and per-minute rates for several services, but no monthly starting price. Pick Infobip for broader channel coverage, customer journeys and conversational AI. Channel use is pay-as-you-go, but rates vary by channel and destination, while subscription pricing requires contacting sales. Neither publishes a free plan, general starting price or seat limits, so total cost needs a quote or usage estimate.

02Pricing compared
Neither product publishes a general starting price, free plan, or free trial. Bandwidth publishes more line-item rates: U.S. SMS ranges from $0.004 to $0.008 per message, depending on number type; MMS is $0.015 to $0.020. Local voice is $0.0100 per outbound minute and $0.0055 per inbound minute. SIP trunking requires a quote, and these rates do not establish your full bill.
Infobip is pay-as-you-go for channel usage, but its rates vary by channel and destination and are not listed here. Its monthly subscription and custom plans require contacting sales; no seat or usage limits are published. Viber can also carry minimum commitments of about $135 or $205 per active sender/service ID, depending on destination. For a cost comparison, estimate your channel mix and volume, then request quotes.
03Features and depth
Bandwidth is the more telecom-oriented choice. Its offering covers programmable voice, SMS and RCS, global SIP trunking, emergency communications, and integrations with contact-center and business communications services. The company also describes direct-to-carrier connectivity and PSTN access in about 70 countries. Its pricing lists specific U.S. messaging and voice services, while SIP trunking is quote-based.
Infobip puts more emphasis on channel breadth and customer engagement. Its listed channels include SMS, email, voice, RCS, Viber, WhatsApp, and video. The platform also includes channel APIs, customer journeys, authentication tools, and conversational AI such as chatbots and voice assistants. That makes it a better fit on paper for teams building cross-channel journeys or AI-supported interactions. The published information does not specify comparable delivery, throughput, or support limits for either product, so feature lists alone do not establish which will perform better for a particular workload.
04Ease of use and learning curve
Neither source publishes seat limits or enough interface detail to compare setup steps or day-to-day usability. Bandwidth’s offering spans APIs, SIP trunking, carrier connectivity, and emergency communications, so teams should confirm which services they need and how they will integrate them. Infobip groups more channels and customer-journey tools in one platform; that breadth may mean more choices to configure, but the published information does not establish how difficult setup is.
For either vendor, ask for implementation requirements, documentation, and a quote based on your actual channels and volumes. Infobip does not publish usage limits, and Bandwidth’s listed rates are not a complete monthly estimate.
Questions people ask
Which is cheaper, Bandwidth or Infobip?
There is no published starting price for either, so we can’t call one cheaper overall. Bandwidth lists specific rates for some U.S. messages and voice services. Infobip’s channel rates vary by destination and require an estimate. Compare quotes using the same volumes and channels.
Which is better for SMS APIs?
Bandwidth lists U.S. SMS prices by number type: $0.004 for 10DLC, $0.008 for short code, and $0.007 for toll-free. Infobip offers SMS alongside other channels, but its rates vary by destination. The better fit depends on your routes, volume, and need for other channels.

Infobip lists AI-powered chatbots and voice assistants for support and other use cases. Bandwidth’s published feature list highlights programmable voice, messaging, SIP trunking, integrations, carrier connectivity, and emergency communications; it does not list conversational AI.
