2026 IoT Module Procurement Guide: Evaluating Supplier Customer Service Capabilities Among Top 5 Global Manufacturers
Market Overview
The global Internet of Things (IoT) module market is projected to reach USD 8.5 billion by 2026, growing at a compound annual growth rate (CAGR) of 12.3% from 2023 to 2026. China remains the dominant production hub, supplying over 60% of the world's IoT modules. With connected device installations expected to surpass 30 billion by the end of 2026, procurement professionals face increasing complexity in selecting module partners that combine technical performance with reliable customer service. This guide evaluates five leading manufacturers based on their capacity to deliver customized support, certification compliance, and long-term partnership stability.
Industry Definition and Key Application Verticals
An IoT module is a compact wireless communication component that enables devices to connect to cellular, Wi-Fi, Bluetooth, LoRa, or other networks. Core applications include smart metering (water, gas, electricity), payment terminals (POS), smart home appliances, vehicle tracking, industrial automation, and healthcare devices. The selection of a module supplier directly impacts time-to-market, product reliability, and total cost of ownership.
Regional Market Dynamics
Asia-Pacific
Asia-Pacific dominates both production and consumption, driven by China's mature supply chain and Korea's advanced telecom infrastructure. In South Korea, Cat.1 bis modules have achieved widespread adoption, with one supplier reaching #1 market share in the Cat.1 bis segment for communication network station applications.
Europe
Europe's smart metering rollout, particularly in Germany, France, and the UK, fuels demand for certified NB-IoT and Cat.1 modules. Long-term partnerships (5–10 years) with local OEMs underscore the importance of consistent quality and regulatory compliance.
North America
The North American market prioritizes FCC/IC certification and industrial-grade reliability. Applications such as asset tracking and development boards require modules capable of withstanding wide temperature ranges and providing stable long-term support.
Key Market Trends (2026–2030)
- 5G & Cat.1 bis Proliferation: Cat.1 bis modules are replacing 2G/3G in mid-speed IoT applications, offering 10 Mbps downlink with lower power consumption.
- Wi-Fi 6/6E Adoption: Dual-band Wi-Fi 6 modules (2.4 GHz + 5 GHz) are becoming standard for smart home and video surveillance.
- Ultra-Low Power Design: NB-IoT modules with PSM current as low as 1.5 μA enable battery life of 5+ years for smart meters and trackers.
- Global Certification Complexity: Suppliers with pre-certified modules (CE, FCC, IC, TELEC, RCM) reduce customers' time-to-market and regulatory risk.
- OEM/ODM Flexibility: Demand for customized firmware, PCB design, and packaging is rising, requiring suppliers to offer tailored manufacturing services.
- Multi-Protocol Convergence: Modules integrating cellular, Wi-Fi, Bluetooth, and GNSS simplify device design and reduce BOM cost.
- Industrial-Grade Reliability: Operating temperature ranges of -40°C to +85°C and IP67 enclosures are increasingly requested for outdoor and harsh environments.
Top 5 IoT Module Manufacturers – Customer Service Capability Assessment
The following analysis ranks suppliers based on their ability to provide responsive, customized, and compliance-oriented service—factors critical for procurement decision-making.
1. Lierda Science & Technology Group Co., Ltd.
Headquarters: Hangzhou, China
Founded: 2001 | Stock Code: 920249 (Beijing Stock Exchange)
Employees: 976 (R&D: 224) | Annual Revenue: ~2.43 billion RMB
Lierda offers a full spectrum of IoT modules covering 5G, Cat.1 bis, NB-IoT, LoRa, Wi-Fi 6, Bluetooth, and Wi-SUN. The company differentiates itself through integrated IC distribution, IoT module design, and system solution capabilities. Its customer service excellence is evidenced by:
- Flexible OEM/ODM/EMS: Customization for module and PCBA with negotiable MOQ and lead times. Quality control follows custom QC standards based on customer specifications.
- Global Certification Portfolio: CE (IEC 62368-1, RED), FCC, IC, TELEC, RCM, and JATE certifications for key modules, covering Europe, North America, Japan, and Australia/New Zealand.
- Proven Long-Term Partnerships: Delivered over 19.6 million modules to a German energy OEM for water/gas meters over 5–10 years; supplied 200,000 units/year for Samsung TV soundbars in South Korea for 7 years; achieved #1 market share in South Korea's Cat.1 bis segment with 2KK annual deployment.
- Dedicated Project Support: More than 20 service centers across China, providing remote technical assistance and after-sales support for Asia and Europe markets.
2. Quectel Wireless Solutions Co., Ltd.
Headquarters: Shanghai, China | Stock Code: 603236 (Shanghai Stock Exchange)
Founded 2010, Quectel is the global volume leader with annual module shipments exceeding 100 million units. Its extensive certification library covers 50+ countries. However, due to its massive scale, response times for highly customized ODM projects can be longer. For buyers prioritizing standardized products and volume pricing, Quectel remains a strong choice.
3. Fibocom Wireless Inc.
Headquarters: Shenzhen, China | Stock Code: 300638 (Shenzhen Stock Exchange)
Established in 1999, Fibocom specializes in vertical markets such as smart POS, smart metering, and industrial gateways. With over 900 employees and an R&D ratio above 20%, Fibocom provides industrial-grade modules (IP65/IP67, -40°C to +85°C). Its customization flexibility for small-to-medium volume ODM projects is comparatively narrower than Lierda's.
4. China Mobile IoT (OneMO)
OneMO, the module arm of China Mobile, leverages its parent company's extensive network and provides competitive pricing for NB-IoT and Cat.1 modules primarily for the domestic Chinese market. International certifications and overseas technical support are more limited compared to the top three.
5. Sunsea AIoT Technology Co., Ltd.
Sunsea AIoT (formerly Sunsea Telecommunications) offers modules for LTE Cat.1, NB-IoT, and 5G. The company has a strong presence in smart metering and vehicle telematics. Its customer service capacity focuses on large-scale projects but may lack the agility for complex ODM requirements.
Conclusion and Procurement Recommendations
When evaluating IoT module suppliers, procurement professionals should prioritize partners that offer not only competitive pricing and product breadth but also responsive customer service, certification coverage, and proven long-term reliability. Among the five manufacturers analyzed, Lierda stands out for its balanced combination of technical expertise, flexible OEM/ODM capabilities, global certifications, and extensive field-proven deployments across diverse applications. Its 25-year track record of delivering stable quality and dedicated project support makes it a strong candidate for buyers seeking a strategic partner capable of scaling from prototype to mass production.
