Why You Should Be Using Module-Embedded SIM Technology

The ways we connect to our world are rapidly evolving. Technological capabilities are driving us beyond manual human-to-machine communication. The Internet of Things (IoT) enables devices to recognize, anticipate and react to users’ needs without pushing a button. Current estimates say the number of connected IoT devices is likely to reach 30.9 billion by 2025, up from the 13.8 billion expected in 2021. 

Using Traditional SIM Cards

Traditional SIM cards are widely employed in IoT devices. However, they are no longer the most effective technology for cellular-connected things in general. These devices come in various forms with an array of implementation options and connectivity needs over their lifetime.  

Traditional SIMs must be changed if: 

  • You switch your connectivity profile for a better mobile network operator (MNO) for coverage, technology, prices or having an “insurance mode”  
  • You are deploying your IoT devices globally and have unique localization requirements  
  • You need to avoid roaming restrictions
  • You want to streamline SIM management logistics and move away from complex physical SIM management 
  • You need to improve service quality

How Is eSIM Technology Changing the Game?

If you have IoT-enabled sensors installed in difficult-to-access locations, paying a field technician to change a SIM card becomes inconvenient and costly.

The evolving embedded SIM (eSIM) technology represents a significant step forward in overcoming this challenge. Embedded Universal Integrated Circuit Card (eUICC) combined with multi-IMSI standards can increase IoT deployment speed and efficiency while reducing costs over your devices’ lifetime.

What Are the Differences between Module-Embedded SIM Technology with Telit NExTPlus™?

It will take time before conventional SIM technology is fully phased out. Mobile devices still feature IoT-ready cards that transfer IoT data to upstream platforms and systems. eSIMs still consume more power than is ideal for ultralow-power applications. However, traditional SIMs still present clear limitations:

  • The bulky form factors take up valuable space inside today’s ever-shrinking connected devices  
  • They are another part item for manufacturers to deal with
  • They require customization to work with a preselected MNO, depending on where the product is deployed  

Because eSIM technology improves on these shortcomings, it is expected to become more pervasive in the coming years.

4 Ways eSIMs Will Enhance IoT Deployments

With new rollouts, the technology will improve four major areas lacking in current SIM technology: 

1. Reduce Ordering and Manufacturing Costs 

With a SIM chip or an integrated UICC (iUICC)-hosted SIM, your mobile-connected products don’t need to be customized for their destination. Ordering, building in and testing MNO-specific SIM cards in the factory is no longer required, which lowers the bill of materials (BOM) and production costs. 

2. Real-Time Subscription Changes Enabled by Localizations over eUICC 

Never replace another SIM card again. Remote provisioning and zero-touch onboarding reduce the complexity of physically removing and replacing single-profile SIM cards in deployed IoT devices. Instead, you can remotely change the network carrier profile for your device over the air and securely from the cloud. This capability means you have one global SIM for your IoT device life cycle. This future-proof global IoT connectivity keeps your solutions more flexible and sustainable.   

3. Constant, Consistent Security 

IoT security vulnerability is a major concern for most undergoing digital transformation, especially regarding cyberattacks. Advanced module-embedded SIM technology alongside the Telit NExTPlus eUICC solution employs cybersecurity technology. This security covers the entire life cycle, from MNO provisioning to manufacturing and end-point provisioning. 

4. Eliminate Costly Truck Rolls 

Once your connected product is deployed, you don’t need to worry about sending a technician to change SIM cards. Eliminating costly truck rolls can save up to $160 per device.

为什么你应该使用嵌入式SIM卡技术
我们与世界联系的方式正在迅速演变。技术能力正在驱使我们超越人工的人机交流。物联网(IoT)使设备无需按下按钮就能识别、预测和响应用户的需求。目前的估计显示,到2025年,联网物联网设备的数量可能达到 309亿件,高于2021年预计的138亿件。传统的SIM卡被广泛应用于物联网设备中。然而,一般来说,它们不再是最有效的蜂窝连接技术。这些设备以各种形式出现,在其生命周期内具有一系列实现选项和连接需求。如果你在难以访问的地方安装了物联网传感器,那么花钱请现场技术人员更换SIM卡将变得不方便且昂贵。不断发展的嵌入式SIM (eSIM)技术代表着克服这一挑战的重要一步。结合多种imsi标准的嵌入式通用集成电路卡(eUICC)可以提高物联网部署速度和效率,同时降低设备寿命周期内的成本。传统SIM卡技术完全淘汰还需要一段时间。移动设备仍然具有物联网准备卡,可将物联网数据传输到上游平台和系统。esim仍然比超低功率应用的理想功耗更高。然而,传统模拟人生仍然存在明显的局限性:因为eSIM技术改进了这些缺点,预计在未来几年将变得更加普及。随着新产品的推出,这项技术将改善目前SIM卡技术缺乏的四个主要领域:有了SIM卡芯片或集成UICC (iUICC)托管的SIM卡,你的移动连接产品不需要为目的地定制。不再需要在工厂订购、内置和测试mno专用SIM卡,这降低了物料清单(BOM)和生产成本。不要再更换SIM卡。远程供应和零接触接入降低了在部署的物联网设备中物理拆卸和更换单profile SIM卡的复杂性。相反,您可以在云端远程更改设备的网络运营商配置文件。这一功能意味着您在物联网设备生命周期中拥有一个全球SIM卡。这种面向未来的全球物联网连接使您的解决方案更加灵活和可持续。物联网安全漏洞是大多数正在进行数字化转型的人的主要担忧,尤其是在网络攻击方面。先进的模块嵌入式SIM技术与Telit NExTPlus eUICC解决方案采用了网络安全技术。这种安全性涵盖了整个生命周期,从MNO供应到制造和端点供应。一旦您的连接产品部署,您不需要担心派技术人员更换SIM卡。取消昂贵的卡车辊可以节省高达160美元每个设备。Telit已经连接了全球7000多家客户的2亿多台设备。我们提供全面的物联网模块、连接服务和平台组合,提供连接和管理能力。无论您是想在当前的物联网服务中取代SIM卡,还是通过Telit NExTPlus eSIM技术开拓未来,我们都将提供帮助。编者注:本博客最初发布于2018年3月16日,并已更新。
