It's a split decision.
Bandwidth is the stronger fit for teams prioritizing programmable voice, U.S. messaging rates and direct carrier or SIP connectivity. Infobip suits developers building customer journeys across a wider set of messaging channels, with AI and two-way conversation features. Both offer communications APIs, but neither publishes SDK, language or self-hosting details on its homepage. Compare traffic destinations and channel needs, then ask each vendor about production limits, data export and the full contract cost.

02Pricing at real usage
Bandwidth has no free plan or trial listed. Its messaging and voice APIs are usage-priced: U.S. 10DLC is $0.004/SMS and $0.015/MMS; local outbound voice is $0.0100/minute and inbound is $0.0055/minute. Short-code and toll-free rates differ, and transcription, recording, conferencing, authentication and other features add separate usage charges. SIP trunking requires a quote.
Infobip’s channels are pay-as-you-go per message or minute, with rates varying by destination and network. It also sells monthly Communication Hub/platform subscriptions and custom packages, but prices and seat and usage limits are not published. The homepage says “Try for free,” while the pricing page lists no free-plan or trial terms, so confirm eligibility and caps. Viber adds a minimum of €115 or €175 per active sender/service ID monthly, depending on destination. Estimate total cost from your traffic mix and destinations.
03API, SDKs and integration
Bandwidth offers programmable voice, messaging and authentication APIs, alongside global SIP trunking. Its Messaging API covers SMS and RCS, with throughput and deliverability insights; its voice offering includes calling features such as transcription and recording. The homepage names integrations with Salesforce Contact Center, Webex Calling, Google, Genesys, Five9 and Microsoft Teams.
Infobip provides channel APIs and communication workflows for messaging and voice. Its platform also covers customer journeys, authentication, programmable voice and interactive marketing or support conversations. The listed channel set includes SMS, Email, Voice, RCS, Viber, WhatsApp and Video. Its homepage does not name third-party integrations. Neither homepage names supported SDKs, programming languages, API protocols, CLI tools or documentation products. Confirm those details with each vendor before choosing an implementation path; also check whether the integrations you need cover your specific product and account configuration.
04Open source, self-hosting and lock-in
Neither vendor publishes an open-source license, self-hosting option or data-export guarantee on its product pages. Treat both as vendor-operated communications platforms unless sales or technical documentation confirms otherwise, and ask for the relevant contract and API terms before implementation.
The architectural differences affect what to examine. Bandwidth emphasizes direct-to-carrier integrations, PSTN connectivity and SIP trunking; ask how number ownership, routing configuration and call records transfer if you leave. Infobip combines channel APIs with customer journeys and conversational tools; ask how to export message, consent and journey data, and what must be rebuilt outside the platform. For either vendor, verify retention, export formats, deletion timelines, number portability and any fees or limits attached to migration. Those answers matter more than the API surface alone when estimating switching effort.
