Welcome to Telnyx eSIMs
The world of IoT is ever-evolving, with new technologies emerging to improve connectivity and device management. Two such innovations are eUICC
and, which play crucial roles in enhancing IoT deployments.
Below we'll provide you with a walkthrough guide on how to purchase and activate your Telnyx eSim.
Step 1: Visit the sim card page
Logged into your account, visit the sim cards page.
Step 2: Purchase an eSIM
Click on the purchase eSims button on the top right. A window will pop up where you can:
Select the amount of eSims you like to purchase.
Select a SIM Card Group to associate the eSim with.
Set the SIM Card Status
Add SIM Card Tags which are helpful for reporting segregation purposes
You can see the activation fee cost and if you require bulk eSIMs please reach out to firstname.lastname@example.org to discuss potential bulk discount pricing.
The status of the eSIM will need to be set to enabled in order to proceed with the activation in the next step but you can always access the QR code from the sim card settings within your account afterwards.
Once you are happy with your settings you can click the purchase button within the pop up window.
Step 3: Activate eSIM with QR Code
Once you have clicked the purchase button, the current window will be replaced with a new window that contains the QR code. You will want to scan this QR code for the device you want to activate the eSIM on.
If you use a mobile phone that supports eSIMs, use your phones camera to scan the QR code. The camera will highlight "mobile plan" underneath the QR code which you can select to proceed with the activation through the phone.
Follow the on screen instructions, the activation process may take a few minutes to connect to the network.
Please make sure to verify that the apn has been set correctly to data00.telnyx.
eSIM: Want to know more details?
We'll delve into the differences and similarities between eUICC and eSIM below, their implications for IoT, and how to choose a provider that will offer seamless connectivity and efficient management.
eUICC and eSIM: Unraveling the technologies
Before diving into the comparison, let's first understand what eUICC and eSIM are and how they fit into the IoT landscape.
What is eSIM?
eSIM (embedded SIM) is a virtual SIM card embedded into IoT devices, smartphones, and wearables. Unlike traditional physical SIM cards, eSIMs are soldered onto the device's motherboard, enabling users to switch between mobile network operators (MNOs) without physically changing SIM cards. This flexibility allows for seamless global connectivity, especially for IoT devices operating across borders.
What is eUICC?
eUICC (embedded Universal Integrated Circuit Card) is the underlying technology that powers eSIM. It's a standardized rewritable memory chip that stores SIM profiles and allows these profiles' secure over-the-air (OTA) management. With eUICC, users can remotely update and switch between multiple MNO profiles, providing enhanced flexibility and simplifying device management.
eUICC vs. eSIM: Similarities and differences
Now that we understand the basics, let's explore the similarities and differences between eUICC and eSIM technologies.
Both eUICC and eSIM technologies aim to improve and flexibility. They enable remote management of devices and eliminate the need for physical SIM card swaps, significantly simplifying IoT deployments. These technologies also empower organizations to switch between MNOs as needed, ensuring optimal coverage and reducing costs.
While eUICC and eSIM share common goals, their specific functions, features, and applications in IoT differ. eSIM is a virtual SIM card embedded in devices, while eUICC is the technology that enables eSIM's remote management capabilities. In essence, eUICC is the foundation that makes eSIM technology possible.
Moreover, eUICC is designed to store multiple SIM profiles, allowing for seamless switching between different MNOs, whereas eSIM is a single virtual SIM card that takes advantage of eUICC's capabilities.
Benefits of eUICC and eSIM in IoT deployments
eUICC and eSIM technologies offer numerous advantages to IoT deployments. They streamline device management by enabling remote provisioning and updates, reduce costs associated with physical SIM cards, and enhance global connectivity by allowing devices to switch between MNOs effortlessly.
SIM cards harness the power of eUICC and eSIM technologies to deliver seamless connectivity, global coverage, and efficient IoT device management. As a result, businesses can remotely manage their devices, access a broad range of MNOs, and ensure optimal connectivity no matter where their devices are deployed.
For example, a logistics company with a global fleet of trucks could use SIM cards to ensure constant connectivity for their vehicles, allowing them to track and manage their fleet in real time. With eUICC and eSIM capabilities, the company can switch between MNOs as their trucks cross borders, ensuring they always have the best available network coverage. These capabilities improve operational efficiency and reduce costs by eliminating the need for multiple physical SIM cards and manual swaps.
Similarly, a smart city deploying IoT devices like smart meters and traffic sensors can benefit from SIM cards. These devices can be remotely provisioned and managed, allowing smooth operation across different regions with varying network providers. With eUICC and eSIM technologies, city officials can ensure their devices remain connected and functional, leading to more efficient resource allocation and better decision-making.
Grasping the distinctions between eUICC and eSIM technologies is crucial for organizations aiming to enhance their IoT deployments. By adopting these technologies, companies can simplify device management, cut costs, and improve global connectivity.
