Building a scalable global customer support operation for a leading eSIM provider

Enabling 24/7 customer experience excellence through scalable support operations.

A rapidly growing South Korean technology company specializing in eSIM technology and portable WiFi devices was experiencing increasing operational pressure as its global customer base expanded. Serving travelers and digital users across multiple countries meant delivering fast, accurate, and professional support around the clock, regardless of time zone or customer location.

As customer inquiries continued to increase, the organization recognized that scaling its internal customer support function would require significant investment in hiring, training, and operational management. Rather than diverting valuable resources away from strategic initiatives, the company sought an experienced outsourcing partner capable of delivering consistent customer support while maintaining operational efficiency and cost control.

What began as a customer support engagement gradually evolved into a strategic operational partnership that strengthened service quality, improved scalability, and enabled the client to focus on accelerating business growth.

What was limiting customer support scalability?

As the business expanded internationally, customer expectations evolved alongside it. Travelers relied on eSIM connectivity before, during, and throughout their journeys, making timely customer assistance a critical component of the overall customer experience.

Supporting customers across global time zones

Providing uninterrupted customer support became increasingly challenging as inquiries arrived from different countries throughout the day. Building an internal team capable of supporting global operations twenty-four hours a day would have significantly increased operational costs while placing additional pressure on management resources.

Balancing quality with operational efficiency

The client wanted to improve customer support without compromising service quality or investing heavily in expanding its internal workforce. Finding a partner capable of maintaining professional communication standards while delivering operational flexibility became essential.

Managing unpredictable support volumes

Customer inquiry volumes frequently fluctuated due to seasonal travel, promotional campaigns, technical issues, and new product adoption. The support operation required the flexibility to quickly absorb higher workloads while maintaining consistent response quality.

Maintaining speed without sacrificing accuracy

Customers expected prompt assistance, but speed alone was not enough. Every interaction required accurate troubleshooting, clear guidance, and professional communication to protect the company's reputation and maintain customer confidence.

Expanding beyond traditional customer support

The engagement initially focused on providing dependable customer service for routine inquiries related to eSIM activation, troubleshooting, and order support.

As confidence in the team's execution grew, the client gradually expanded the scope of responsibilities.

The engagement evolved beyond standard customer support to include:

• Pre-sales guidance
• During-sales assistance
• After-sales support
• Additional operational responsibilities
• Continuous process improvements
• Flexible support during peak demand periods

Rather than functioning as an outsourced support vendor, FBSPL became an operational extension of the client's customer experience team.

Building a structured customer support framework

To create a scalable and sustainable support operation, FBSPL introduced a structured operating model focused on consistency, collaboration, and continuous improvement.

Establishing dedicated 24/7 support operations

Dedicated customer support specialists were deployed through shift-based scheduling to ensure continuous coverage across multiple time zones. Standard operating procedures, escalation protocols, and supervisor oversight ensured that every customer interaction followed consistent quality standards regardless of when support was requested.

This operational structure enabled uninterrupted customer assistance while providing the flexibility to accommodate changing support volumes.

Standardizing quality across every interaction

Maintaining consistent service quality required more than simply answering customer queries. Structured onboarding programs, standardized training modules, quality assurance reviews, and documented operating procedures helped ensure every team member followed the same customer service standards.

Regular coaching sessions strengthened product knowledge, communication skills, technical troubleshooting capabilities, and customer handling techniques, enabling the team to resolve issues accurately while delivering a positive customer experience.

Strengthening communication and operational governance

Transparent communication played an important role throughout the engagement. Slack enabled real-time collaboration between support teams and client stakeholders, while scheduled review meetings created opportunities to evaluate performance, discuss operational challenges, and identify improvement opportunities.

A dedicated project manager served as the primary point of contact, ensuring faster decision-making, streamlined escalations, and better alignment with the client's evolving business priorities.

Optimizing ticket management

Customer support workflows were strengthened using Freshchat and Freshdesk. Existing ticket management processes were refined to improve prioritization, response tracking, SLA monitoring, and internal collaboration.

Templates, checklists, and standardized workflows reduced process variability while allowing support specialists to dedicate more attention to complex customer inquiries requiring technical expertise or personalized assistance.

Driving continuous operational improvement

Beyond day-to-day support, the team continuously identified opportunities to improve customer experience and operational efficiency.

Optimizing eSIM voucher information

The team recommended improving activation guidance and carrier-specific instructions to reduce customer confusion and improve first-time activation success.

Enhancing Freshchat workflows

Additional labels and categorization methods improved ticket routing, knowledge sharing, and collaboration between support agents.

Streamlining review management

The team developed an alternative review management process that simplified review identification and response handling following platform changes.

These initiatives demonstrated a proactive approach to operational excellence, extending the partnership beyond traditional customer support delivery.

Measurable operational outcomes

Following the initial onboarding and training period, the client began experiencing noticeable operational improvements within a few months of the engagement. As processes matured and collaboration strengthened, FBSPL became a trusted operational extension of the client's customer experience function.
