What exactly is Twilio?

Twilio is an API-first cloud platform for creating customized communication paths. In concrete terms, technical teams use APIs to manage voice, SMS, WhatsApp, chat, video and even authentication. Coverage is international, with local, mobile and toll-free numbers in 100+ countries. Target audience: scale-ups, major accounts, publishers and all SMEs with in-house devs.

On the product side: calls and video, voicemail with transcription, programmable switchboard, transfers and conferences. For contact centers: ACD, omnichannel routing, AI recording and analysis, real-time supervision, outbound campaigns. On the AI side: sentiment analysis, intent detection and automatic summaries. Integrations: Salesforce, HubSpot, Zendesk, Microsoft Dynamics, Slack, etc. Security: TLS and SRTP encryption, RGPD, European data residency options.

Feedback: well-documented, reliable APIs, high scalability. But the platform is considered complex, pricing is sometimes difficult to predict, and support is perceived as variable from case to case. This is consistent with a very developer-oriented, à la carte business model.

Rates

  • Twilio: Pay-as-you-go and flat-rate plans, prices not disclosed here. Billing based on actual usage.
  • Kavkom: clear and fixed packages, unlimited France/US/CA from €30 excl. user/month and predictive dialer from €60.

 

In short, Twilio is right for you if you want to customize everything via API and manage international multi-channel. If you prefer a turnkey solution, with all-in-one VoIP telephony, native dialer, and French-speaking human support, solutions like Kavkom are clearly worth considering.

Our opinion on Twilio

In use, Twilio impresses with its well-documented APIs, rapid integration and international coverage of voice, SMS, WhatsApp and video. Call quality is stable, and real-time analysis is a real help to management.

But the platform is complex, pay-per-use pricing is hard to predict, and support can be patchy, with some incidents. Some teams prefer a turnkey solution like Kavkom. The table below summarizes the key points.

Trustpilot Twilio
Capterra Twilio

Imagine you’re a sales manager, support manager or in charge of multi-site operations. You’re looking at Twilio to add SMS and Voice to your business tools, and you want to know how it’s going day-to-day. We’ve sifted through recent reviews from Google, Trustpilot and Capterra. Here’s what users are saying, and what it means for your team.

 

Overall opinion

Feedback on Twilio is mixed. On the one hand, users emphasize the well-documented, reliable and scalable APIs, which facilitate the integration of SMS and Voice into business applications. Call and message quality are judged to be good. On the other, several reviews point to uneven customer support, billing issues and a very powerful platform but with a steep learning curve.

“Twilio APIs are well-documented, easy to use and enable rapid integration of SMS and Voice functionality.” – Capterra

“Twilio offers reliable and scalable APIs, the quality of calls and messages is very good.” – Trustpilot

As for recurring limitations, support responsiveness is a recurring theme, as are one-off technical incidents and billing difficulties.

“Billing difficult to understand with errors, support often slow.” – Trustpilot

Operationally, this means that your developers can make rapid progress on integration thanks to the docs and APIs, but you need to allow time for technical onboarding to master the platform and anticipate possible delays on the support side in the event of an incident. For a growing team, this is a good way of scaling up, provided you have an autonomous tech team and internal workaround procedures if a ticket drags on.

 

Pricing & evolution

Opinions highlight flexible usage-based pricing, perceived as clear in principle, but sometimes difficult to predict over time. Some users report discrepancies between expected and actual costs when volumes increase, or when interruptions necessitate resumptions.

“Usage-based pricing is hard to predict.” – Google

In concrete terms, for an annual budget, this can create discrepancies at the end of the month if SMS or call volumes vary greatly. No reviews mention volume discounts, cancellation fees or installation costs. Nor do the testimonials list the breakdown of features by plan.

 

Kavkom side comparison, on the same subject price and team evolution :

  • Kavkom offers fixed-rate packages in euros with unlimited calls to certain zones. For example, Téléphonie Cloud Plus FR/US/CA at €30 per user per month, or €24 annually. Dialer Predictive starts at €60 per month. It’s easier to budget if your volume varies.
  • Twilio, according to reviews, is pay-as-you-go and can be flexible at start-up, but less predictable in the event of activity peaks.

If your team changes size frequently, Kavkom’s flat-rate approach can reduce the risk of budget drift. If you have a tech team that fine-tunes volumes and optimization, Twilio’s usage model is still the right choice.

 

VoIP features

Reviews focus on Voice and SMS APIs, communication quality, and the integration ecosystem. Users appreciate the modular APIs, capable of covering SMS and telephony, with advanced customization possibilities.

“Modular APIs for SMS and telephony, excellent ecosystem of integrations.” – Capterra

“Lots of flexibility to customize features.” – Capterra

Concerns cited in reviews: powerful but complex platform, error handling sometimes difficult, and occasional interruptions.

“Large learning curve and difficult error handling.” – Trustpilot

For a manager, this means making clear organizational choices:

  • If you have developers, you can build customized SMS and Voice scenarios, and integrate your processes in fine detail.
  • If you’re looking for a ready-to-use tool for non-technical agents, setting it up may take some time.

 

Kavkom’s comparison, on the same ready-to-use VoIP functional bricks:

  • Kavkom offers a cloud switchboard, IVR, queues, transfers, recording, supervision, and a predictive dialer for campaigns. The interface is designed for sales teams and call centers.
  • Twilio reviews don’t detail turnkey agent tools, but emphasize APIs and integration.

In practice, Twilio adapts well to a custom application context. Kavkom is well suited if you’re looking for an immediate operational package for your teams.

 

VoIP security

The notices analyzed do not detail security or authentication mechanisms. However, they do mention technical incidents and occasional interruptions, as well as persistent bugs in some cases.

“Service interruptions sometimes observed.” – Google

For a support team or call center, every outage has a direct cost. You’ll need an internal continuity plan, such as a temporary switchover procedure, especially if your business is sensitive to interruptions.

On the Kavkom side, the official sales pitch emphasizes high availability and resilient cloud hosting. As Twilio’s reviews don’t quote quantified measurements, the comparison remains on the perception of incidents on Twilio’s side versus availability positioning on Kavkom’s side. To be verified contractually in both cases.

 

Steering & KPIs

User feedback focuses on the well-documented API, which is useful for exposing or retrieving data. Reviews don’t mention ready-to-use dashboards or one-click exports. In other words, you’d be better off using your own dashboards, fed by the API.

“Clear documentation and active community, easy API integration.” – Trustpilot

For a manager, this means you can track KPIs with your BI tools, but you’ll need a bit of development to get there. On the Kavkom side, the suite offers ready-made dashboards and CSV export for a quick start without code. Both approaches are valid, depending on whether you prefer low-code or API-based management.

 

Phone number availability

The notices studied do not mention country coverage, types of issue available, or porting experience. No feedback on coverage gaps is cited in this corpus.

In practice, this calls for caution if you need to open up several countries quickly. Ask for an availability list, and test a small batch before rolling out the whole network. For Kavkom, the current offer includes national and international numbers with porting, according to the product description. For Twilio, the reviews do not specify this point, so it remains to be verified on quotation.

 

Support & responsiveness

This is the most divisive aspect of the feedback. Many reviews praise the clear documentation and active community, which helps with self-service. At the same time, users report that support is hard to reach, not very responsive to complex tickets, and takes a long time to deal with billing issues.

“APIs work well, but customer support sometimes leaves something to be desired.” – Google

“Unreachable customer support, persistent technical issues.” – Trustpilot

“Billing difficult to understand, errors, support slow to respond.” – Trustpilot

Direct business impact: in the event of a production incident, you risk being stuck for longer, with agents waiting and conversations lost. If your model depends on strong continuity, plan for internal escalation, a technical runbook, and redundancy if possible. On the Kavkom side, the advertised support is human and French-speaking, but the real evaluation is made by use. In Twilio reviews, self-service is a strong point, but support responsiveness is variable.

 

Third-party integrations

On this point, the reviews are rather positive. They speak of an excellent ecosystem of integrations, facilitating multi-channel use between SMS and telephony, and a flexible API for building your own connections.

“Excellent ecosystem of integrations, fast API integration.” – Capterra and Trustpilot

This means you can connect your business tools and CRM with a good level of customization. Reviews don’t cite any limits per plan. In comparison, Kavkom has ready-made native integrations with popular CRMs and an open API. If you have a dev team, Twilio’s flexibility is an asset. If you want to quickly plug in a CRM without code, the Kavkom approach is more straightforward.

Conclusion: should you choose Twilio, or another solution?

Twilio is suitable if you have a technical team and API-first needs: build customized voice/SMS/WhatsApp/video journeys, integrate Salesforce/HubSpot/Zendesk, deploy internationally, and leverage real-time analytics and AI. This is relevant for scale-ups/publishers who want to finely control multi-channel and absorb peaks via pay-as-you-go.

Avoid if your teams are non-technical, if you’re looking for a ready-to-use tool, predictable pricing and assisted onboarding: reviews point to a complex platform, hard-to-predict cost-per-use and uneven support.

Kavkom ticks these boxes on the turnkey side: fixed-price packages from €30 excl. tax/user (unlimited FR/US/CA), predictive dialer, supervision and ready-to-use dashboards, guided commissioning, commitment-free, pro-rata billing, and French-speaking human support. A direct alternative for rapid deployment and code-free team management.
