L’École Française improves reachability by 15 points with Diabolocom Mobile: more contacts, more conversions

A demanding sales strategy requires constant reachability

L’École Française is an online training provider that supports individuals and professionals from high school level to postgraduate degrees. To meet its goals, the company relies on a 40-person sales team in Paris and a total staff of 100.

With 8,000 to 10,000 outbound calls every day, success depends on reaching prospects quickly—and being able to receive their return calls. A missed call or blocked number can mean a missed opportunity. Which is why always being reachable, even outside the office, is critical.

And that’s exactly where Diabolocom Mobile delivers.

A multi-layered challenge before Diabolocom Mobile

Before launching Diabolocom’s mobile offering, several pain points were holding the sales team back:

• Limited responsiveness outside the office resulted in missed calls during commutes or business travel.
• No unified sales journey – A single number for calls and SMS became essential to maintain continuity across channels.
• Complicated mobile fleet management – Assigning business numbers based on sales activity was a constant admin headache.
• Loss of CCaaS benefits on mobile – Mobile use meant losing access to CRM integration, analytics, and reachability metrics.

In short, L’École Française needed a solution that combined mobility, sales performance, tech continuity, and operational control.

A unified, high-performing omnichannel sales journey

Already a CCaaS customer, L’École Française expanded its omnichannel strategy with Diabolocom’s mobile solution. This professional mobile plan—available via SIM or eSIM—allows sales reps to make and receive calls and SMS directly from their mobile phones, while staying fully connected to Diabolocom’s platform. Every call is logged, analyzed, and synced to the CRM.

Thanks to this end-to-end continuity, teams stay reachable, autonomous, and fully informed—whether at their desks or on the go.

Immediate impact: +15 points in reachability.

Every agent at L’École received a SIM card and a dedicated mobile number within days.

Another key factor: Diabolocom’s mobile numbers are rarely flagged as spam, ensuring high deliverability and reducing the risk of losing valuable contacts.

As a certified fixed and mobile operator, Diabolocom controls the entire production chain. L’École Française now benefits from a single point of contact for all telecom operations—simplifying day-to-day management, saving time, and improving overall service quality.

A smooth rollout, completed in just 10 days

The team completed implementation in 10 days, including hands-on training and in-person workshops. Diabolocom activated the SIM cards immediately, and the number portability process took just three weeks. Rapid time to first value ensured service continuity and improved outcomes within a short timeframe.

“Setup was super easy, and the whole thing was up and running really fast.”

The team especially appreciated how simple the process was on their end: no technical complexity, immediate onboarding, and strong support from Diabolocom—both during setup and ongoing operations. As Ludovic Lanthier notes:

“The solution is solid and well-designed. The support team is incredibly sharp, technically skilled, and responsive.”

A solution that benefits sales, supervisors, and the entire business

Today, the mobile solution is delivering results across all levels of the company:

• Sales reps can take calls anywhere, without disrupting the follow-up process.
• Supervisors get full visibility into mobile activity—usage, stats, individual performance.
• Admins retain access to Diabolocom’s reporting tools, CRM integration, and full traceability.

All with crystal-clear call quality, full compliance with industry regulations, and expert technical support.

A trusted partner for long-term performance

L’École Française also highlights the quality of Diabolocom’s support: expert, available, and proactive at every stage. By choosing a solution built for real-world field conditions, the organization has equipped itself with a strategic lever to improve conversion rates and strengthen the sales process.

The partnership is continuing to grow with new features like SMS monitoring and upcoming WhatsApp integration—further enhancing L’École Française’s mobile-first omnichannel strategy.
