Meet the Line Card: SIMCom Wireless Communication Modules

Introduction to SIMCom wireless communication modules

The shift to truly mobile IoT devices has transformed how we design connected systems - and SIMCom has played a defining role in making it possible. Founded in 2002 and now part of Sunsea AIOT, SIMCom is a global leader in certified wireless communication modules, offering cellular and GNSS modules across 2G to 5G, including CAT-1, LPWA, and smart modules.

For engineers navigating the sunset of 2G and 3G networks, or planning their next-generation edge AI and telematics deployments, SIMCom provides a comprehensive, cost-effective and well-supported platform.

Product Focus

SIMCom’s product line includes:

• 2G / 3G / 4G / 5G cellular modules

• LTE CAT-1, CAT-M and NB-IoT

• Smart 5G modules with integrated OS and application processors

• GNSS and combined GSM/GNSS modules

• LPWA, LTE-A and Wi-Fi modules

This portfolio allows designers to tailor solutions to regional infrastructure, BOM cost, and application needs with form factors and interfaces that simplify design-in.

Competitive Positioning

With major rivals like Quectel (now on the US Entity List), u-blox (exiting GSM), and Telit Cinterion in transition, SIMCom offers clear advantages:

• Low cost, short lead-times, excellent availability

• Certified modules for global carriers

• Wide chipset support (Qualcomm, ASR, others)

• Dual GSM/GNSS modules to simplify design and reduce BOM

• Smart modules that bundle CPU + 5G for faster time-to-market

SIMCom’s role is to make cutting edge technology usable and certifiable for real-world deployment and that’s exactly what they excel at.

Industry Applications

SIMCom wireless communication modules are widely adopted across:

• Industrial IoT and telemetry

• Asset tracking and fleet monitoring

• Smart meters and utility infrastructure

• Automotive telematics (IATF 16949-qualified parts)

• Edge AI and smart vision applications with integrated compute modules

Their flexible platform options support both cost-sensitive deployments and high-performance connected computing, depending on project scope.

Local Support

SIMCom’s global operation is anchored in Shanghai, with manufacturing expansion underway in Brazil and India to support resilient global supply.

Ineltek works directly with SIMCom’s UK and European engineering teams, offering fast technical feedback, part number cross-referencing, and design guidance for engineers migrating from other module vendors.

Why SIMCom?

SIMCom modules help engineers move fast—whether you’re simplifying your GSM/GNSS design, transitioning from 2G to LTE, or reducing BOM complexity with a smart 5G module that bundles compute and connectivity.

Their extensive product certification, agile supply chain, and broad regional coverage make them a trusted partner for projects that demand both connectivity and cost control.
