eSIM is the future of SIM technology. Technically known as eUICC, it is an unlocked SIM card that enables you to swap between pre-negotiated carrier services "over-the-air" without the need to physically change the SIM card.I NEED IT
One SIM card and one invoice for global coverage with multiple carrier support per country. Technically known as UICC and delivered in the form of 2FF (mini), 3FF(micro), 4FF (nano), or solderable MFF2 SIMs.I NEED IT
Our self-service platform, with API, is tailored to give you control of your SIMs: enabling switching your SIM on/off, setting data limits, seeing real-time SIM sessions, setting up notifications & alarms, and deploying many other value-added services. All this saves your time and helps you scale your IoT business quicker.
Our eSIM & self-service SIM provisioning platform is tailored for scaling IoT service providers.
Relax, there are no hidden fees or complex contracts. You can cancel your subscription any time with no extra charge.
We are independent and will choose the best pre-negotiated deal from our 12 carrier partners worldwide! We are not another carrier or aggregator, think of us as your connectivity department.
Every IoT business starts small and with just a few devices. Getting those devices connected is usually not much of an issue. However, when your business begins scaling and production ramps up, then shortcuts made in the early days might come to haunt. It’s much more painful to fix those issues afterward when you have thousands or tens of thousands of devices already rolled out.In this article, we are focusing purely on connectivity matters that you, as an IoT device maker or service provider, need to consider from day 1. Proper connectivity backup implementations need to be addressed together with the system of using and testing SIM cards throughout the production phase.
Historically, the SIM Operating System (OS) contained all the functionality and essential services. However, with the growing need for retaining subscribers, carriers have begun offering additional value-added services. As the value-added services were highly customized to a specific carrier's use case, the SIM manufacturers had to figure out how to offer such services on top of the basic features. Therefore extra features and services were moved to standalone units called SIM applets.
eSIM (eUICC) is introducing possibilities which were not possible before. Yet, every innovation comes with technical aspects that need to be considered. In our eSIM Series, we have already covered how eSIM technically works. Also, we have learned that the two new main components for eSIM are Subscription Manager Data Preparation server (SM-DP) and Subscription Manager Secure Routing server (SM-SR). The first, SM-DP, is the database where carrier (telecom) profiles are stored. And the SM-SR handles the secure information passing between the server and the eSIM.
