For a global smart technology brand with hundreds of millions of users and a wide range of products, after-sales follow-up is a critical touchpoint that connects the brand with its users. It directly affects whether users continue to trust the brand and whether they are willing to support its reputation.

However, traditional manual after-sales follow-up models have gradually exposed problems such as high labor costs, low efficiency, and inconsistent service quality. These issues have become major obstacles to improving service levels. A leading global smartphone brand once faced exactly this challenge. As its business continued to expand, the demand for after-sales maintenance follow-up surged rapidly, and the existing manual follow-up team could no longer handle the growing volume of service requests.

Against this background, the brand partnered with Instadesk to introduce an AI Call Center solution, comprehensively upgrading and restructuring the entire after-sales follow-up process. As a result, the brand successfully reduced the workload equivalent of six full-time customer service agents and increased customer satisfaction by 15%. After-sales service was transformed from a “cost center” into a “value creation center,” creating a replicable best-practice model for intelligent after-sales service in the smartphone industry.

I. Core After-Sales Challenges Faced by the Smartphone Brand

In today’s fully digital and mobile-driven environment, user expectations for after-sales service have gone far beyond simply “solving the problem.” Customers now expect an end-to-end service experience that is efficient, accurate, and human-centered.

With over 100 million users and a broad product portfolio, this smartphone brand operates across diverse after-sales scenarios. Different service types require different follow-up approaches. However, the limitations of the traditional manual follow-up model made it impossible to meet large-scale service demands. The key challenges were concentrated in three areas：

1. High Labor Costs

After-sales follow-up is a crucial part of the service loop, covering the entire process from order ation and service reminders to post-repair care. Previously, the brand relied on a model combining human agents with standardized scripts. For each follow-up call, agents had to manually dial numbers, verify customer information, and record feedback.

If customers missed the call due to work or other reasons, agents had to call again—sometimes multiple times. Since customer needs varied, agents often had to adjust their communication strategies on the spot, significantly increasing the duration of each call. This labor-intensive service model not only drove up operating costs but also made it impossible to scale follow-up coverage efficiently.

2. Inconsistent Service Quality

The core competitiveness of after-sales follow-up lies in achieving standardized service while addressing individual customer needs. However, traditional manual follow-up models struggle to balance these two goals.

The brand’s follow-up scenarios included mail-in repair ation, in-store appointment rescheduling, spare parts arrival notifications, and post-repair satisfaction surveys. Each scenario required different communication logic and key messaging. Due to differences in agents’ professional skills, communication abilities, and emotional states, scripts were often not executed consistently. This “agent-dependent” service model resulted in uneven customer experiences. In some cases, information inaccuracies or poor communication led to customer dissatisfaction, ultimately affecting brand perception.

3. Lack of Data-Driven Service Optimization

Customer feedback collected during after-sales follow-up is a valuable resource for improving product design and service quality. However, under the traditional manual model, most feedback existed as unstructured data. Agents recorded key points using handwritten notes or basic spreadsheets, while large volumes of call recordings were never systematically analyzed.

As a result, the brand was unable to convert massive user feedback into quantifiable and analyzable data. Common complaints such as “long repair waiting times” or “slow spare parts delivery” could not be accurately traced to root causes without centralized data analysis. Personalized suggestions from users were also difficult to deliver to relevant departments in a timely manner. Consequently, service improvements relied largely on experience and intuition rather than precise, data-driven insights.

II. How Instadesk AI Call Center Empowers After-Sales Service

To address these challenges, Instadesk leveraged its expertise in AI and intelligent calling technologies to deliver a customized, end-to-end AI Call Center solution. Centered on the AI Call Center platform, the solution covers four critical after-sales follow-up stages and enables full-process automation—from work order triggering to data feedback—while deeply integrating with the brand’s internal systems.

1. Full Coverage of the After-Sales Service Lifecycle

Mail-in Repair Order Confirmation

Once a user submits a mail-in repair request, the system automatically retrieves order details from the brand’s order management system, including pickup address, device model, fault description, and expected pickup time. A personalized outbound task is generated, and the AI voice agent proactively calls the user with human-like speech. The system s repair details, guides users to select pickup times, and sends ation messages to their mobile phones.

In-Store Appointment Follow-Up

When users request appointment changes, the AI Call Center accesses real-time data from the store management system to check available time slots. Multiple rescheduling options are provided, and ed appointments are synchronized back to the store system. Confirmation messages are sent via SMS or messaging platforms to ensure users receive accurate information and avoid unnecessary store visits.

Spare Parts Arrival Notification

The system integrates with the brand’s warehouse and logistics systems. Once spare parts arrive and pass inspection, outbound calls are automatically triggered to notify users. Store location, business hours, and estimated repair time are communicated. For unanswered calls, the system schedules follow-up attempts and sends reminder messages to ensure timely service.

Post-Repair Care Follow-Up

Three days after users receive their repaired devices, the system initiates follow-up calls. Through multi-turn conversations, it s device usage status and collects feedback on repair quality, service attitude, and process convenience. Keywords are automatically recorded, and when negative sentiment is detected, the user is flagged as high priority and transferred to a human agent for follow-up to prevent escalation into complaints.

2. Advanced Technology Ensuring Service Quality and Efficiency

Powered by long-context AI capabilities, the Instadesk AI Call Center can process entire conversation histories and historical work orders, accurately understanding complex requests such as “cancel the mail-in repair but keep the original device.” The system adapts well to background noise, accents, and dialects, maintaining a speech recognition error rate below 6%, ensuring smooth and accurate communication.

The platform dynamically retrieves data from CRM and logistics systems to deliver personalized responses. For inquiries beyond predefined scenarios, it can generate reasonable answers automatically, reducing unnecessary transfers to human agents. After each call, the system conducts automated quality analysis across intent, sentiment, and keywords, generating summaries and continuously enriching the knowledge base.

3. Building a Closed Data Loop

One of the core strengths of the Instadesk AI Call Center is its ability to connect data collection, analysis, and application. Unstructured customer feedback is transformed into structured, reusable data to support service optimization.

After each call, conversations are transcribed, key information is extracted, and data is synchronized to the brand’s customer data platform to enhance user profiles. The system automatically generates multi-dimensional reports covering follow-up coverage rates, call connection rates, and satisfaction levels. Managers can monitor overall performance through visual dashboards and identify service bottlenecks with precision.

III. Measurable Business Value After Implementation

1. Significant Reduction in Labor Costs

The AI Call Center operates 24/7 and handles over five times the daily call volume of human agents. Core follow-up coverage increased from under 60% to over 80%. More than 90% of standardized follow-up tasks are automated, freeing six full-time agents to focus on complex complaints and high-value users. Call connection rates increased from below 60% to over 82% through intelligent scheduling.

2. Improved Service Consistency

Standardized scripts combined with flexible, emotion-aware interactions ensured consistent yet personalized service. The system empathizes with dissatisfied users, explains reasons clearly, and communicates improvement measures, significantly enhancing user perception.

3. Data-Driven Service Optimization

By analyzing large volumes of feedback, the system identified three major service bottlenecks. The brand optimized repair workflows, increased staffing during peak periods, partnered with logistics providers to improve delivery speed, and simplified appointment processes.

IV. Conclusion

This case demonstrates the transformative value of AI Call Center solutions in improving service efficiency, reducing operational costs, and enhancing customer experience. By adopting Instadesk AI Call Center, the smartphone brand reduced six full-time positions and achieved a 15% increase in customer satisfaction, successfully transforming after-sales service into a value-generating function.
