Twilio Frontline was built to help customer-facing teams stay connected on the go, whether that meant real estate agents closing deals from the field or healthcare workers checking in on patients. But as customer needs evolved, it became clear that a one-size-fits-all mobile solution couldn’t keep up with the demand for flexibility, deep integration, and control.

Frontline entered End of Sale on February 9, 2023, and since then, we’ve focused on helping teams transition to solutions that better fit their unique workflows. Building on that direction, we’re now officially retiring the product on September 30, 2026. The app will remain available to existing customers through that time, but is no longer under active development.

What customers can do next

We recommend taking a look at Twilio Flex for customizable contact center workflows, or one of these mobile-first partners:

• SpokePhone: Our preferred partner for most mobile-first use cases like sales, service, and field teams. SpokePhone has deep integration with the Twilio platform, supports Voice and all Conversations channels, offers robust call routing, transfers, and analytics, and works seamlessly alongside Flex deployments.

• Quo (previously OpenPhone): Best for teams that only need Voice, SMS, and MMS. Features include a collaborative team inbox, AI-powered call transcription and summaries, voicemail transcription, and automated SMS replies for faster customer response.

• Fastcall: Ideal for Salesforce-centric teams. Provides deep integration with Salesforce tools, supports Voice, SMS/MMS, and additional channels like WhatsApp, and includes AI-based conversational insights.

For support navigating options or finding the right fit, customers can connect with their Twilio Account Team or reach out to Sales.

Twilio is grateful for everything customers have built with Frontline, and is here to support thoughtful, seamless transitions as teams plan what’s next.

Here’s to what gets built next,

–Team Twilio

Flex helps businesses create tailored customer engagement experiences, no matter where their teams work. To extend that power beyond the desktop, we introduced Flex Mobile to keep teams connected and productive on-the-go.

During Flex Mobile’s time as a beta product, it became clear that no two organizations use the app in the same way, which is a testament to Flex itself—Flex’s core strength has always been its flexibility, which empowers you to shape customer experiences to fit your team’s unique needs.

As we listened to your feedback and observed how you used Flex Mobile, we saw that a single mobile app can’t capture the unique requirements of every organization. Rather than stretching one app to fit all use cases, we decided to do what Twilio does best: empower you with the tools, services, and trusted partners you need to build or choose the right mobile solution for your business. 

As a result, we’ve decided not to move Flex Mobile into General Availability. Flex Mobile will End of Sale (EOS) on September 30, 2025. After this date, the Flex Mobile app won’t be available to new users. If you’re already using Flex Mobile, rest assured that we’ll continue to support you throughout the transition period.

We haven't set a retirement date yet, but when we do, we’ll provide you with advance notice and the resources to help you make a smooth transition. Flex remains an important component of our long-term vision and we’re continuing to invest in Flex UI and APIs.

Customers looking for mobile alternatives are encouraged to explore:

• SpokePhone: Supports most mobile-first use cases like sales, service, and field teams. SpokePhone has deep integration with the Twilio platform, supports Voice and all Conversations channels, offers robust call routing, transfers, and analytics, and works seamlessly alongside Flex deployments.
• Quo (previously OpenPhone): Best for teams that only need Voice, SMS, and MMS. Features include a collaborative team inbox, AI-powered call transcription and summaries, voicemail transcription, and automated SMS replies for faster customer response.
• Fastcall: Ideal for Salesforce-centric teams. Fastcall provides deep integration with Salesforce tools, supports Voice, SMS/MMS, and additional channels like WhatsApp, and includes AI-based conversational insights.

We’re grateful for everything you’ve built with Flex Mobile, and we understand that change isn’t always easy. If you need guidance or support, we’re here to help you as you plan your next steps.
