Plug-and-Play 4G/5G Android TV Boxes: Reliable Streaming Solutions

In many commercial and industrial scenarios, a stable wired network is not always available. This is why demand for an Android TV box with a SIM card slot continues to grow, especially among system integrators, telecom partners, and B2B buyers working in hotels, IPTV platforms, education, and digital signage.

At Amedia, we regularly receive questions about which Android TV boxes can support 4G or 5G SIM cards and what level of customization is realistically possible. This article provides clear and practical guidance based on actual hardware design and manufacturing experience.

SIM Card Support in Android TV Devices

SIM card support is not just about adding a slot. It is tied to platform requirements and physical design constraints.

Customizable Android TV Boxes With SIM Card Slots
For projects that require mobile connectivity, Amedia provides standard Android TV boxes based on AOSP (Android Open Source Project). These models can be customized at the hardware level to include Nano-SIM or Micro-SIM slots and integrate 4G LTE or 5G cellular modules. Antenna layouts can be optimized, and dual-network operation combining Ethernet and cellular data is possible.

Enclosure Material and Antenna Configuration
To meet the heat dissipation and performance requirements of different scenarios, we offer flexible enclosure options. Our products default to lightweight and cost-effective plastic enclosures, suitable for most indoor commercial environments. For special scenarios that require long-term high-load operation or face challenging thermal conditions, we support upgrades to metal enclosures. Metal enclosures not only effectively improve heat dissipation efficiency to ensure stable device operation but also allow for optimized antenna layouts.

• Standard 4G Configuration: Typically equipped with 2 external LTE antennas to ensure stable mobile network connectivity.
• Enhanced Configuration: Can be further expanded to include 2 external Wi-Fi and Bluetooth antennas, totaling 4 external antennas, significantly enhancing wireless signal strength, coverage, and connection stability.
• High-end 5G Configuration: To achieve higher network speeds and lower latency, 5G modules usually require a more complex antenna system, and the number of antennas will increase accordingly (e.g., 4 or more) to support multi-band and MIMO (Multiple-Input Multiple-Output) technology, ensuring optimal 5G network performance.

The minimum order quantity for this type of hardware customization is 100 units, ensuring proper tooling, testing, and supply stability.

Practical Applications of 4G and 5G Android TV Boxes

SIM-enabled Android TV boxes are particularly useful where fixed broadband is unreliable or unavailable. Especially in areas with weak network infrastructure, such as remote mountainous regions where Ethernet cabling is absent, our 4G/5G devices can play a crucial role in providing stable and reliable network access.

These applications include hotel IPTV systems in regions with limited wired infrastructure, telecom operator bundles combining Android STBs with prepaid data plans, digital signage installations in shopping malls and transportation hubs, education and training terminals in remote areas, and retail displays that require centralized management over mobile networks. Cellular connectivity simplifies installation and significantly reduces dependence on local wired network conditions.

Development Boards With SIM Support

For customers focusing on software development or early-stage prototyping, Amedia also provides development boards for embedded systems. These boards commonly support SIM card connectivity and are used for custom Android or Linux system development, industrial control panels, smart terminals, and proof-of-concept testing before mass production.

If you are evaluating hardware before committing to a full OEM project, our development board portfolio offers a practical starting point.

OEM and ODM Customization Services

Amedia works closely with B2B clients to deliver customized Android TV box solutions that meet specific technical and commercial requirements. Our OEM and ODM services cover SIM card slot integration, cellular module selection, PCBA redesign, antenna tuning, housing re-molding including ID (Industrial Design) and MD (Mechanical Design), branding, packaging, boot animation, and firmware optimization.

Details about these capabilities are available through our OEM and ODM customization services page.

Experience You Can Rely On

With years of experience manufacturing Android TV boxes and embedded devices, Amedia serves distributors, operators, and solution providers worldwide. Our engineering team understands the practical challenges of combining Android platforms with cellular hardware, providing guidance before production begins to avoid unnecessary redesigns and ensure a stable, compliant final product.

Choosing the Right SIM-Enabled Android TV Box

Before starting a project, clarify the following: whether the system requires Google-certified Android TV or standard AOSP Android, the expected production volume, the required network type (4G LTE or 5G), and the operating environment (indoor, outdoor, or mobile use). Defining these requirements early allows Amedia to recommend the most suitable hardware platform and customization path.

Conclusion

Amedia offers flexible and proven solutions for projects requiring Android TV boxes with SIM card slots. Most of our standard Android TV box models can be re-designed to include 4G or 5G connectivity, starting from a minimum order of 100 units. From development boards to mass-produced OEM devices, Amedia supports customers throughout the entire process, from technical evaluation to long-term supply chain support.
