Multi-IMSI is how the World Connects

Software-Defined LTE

Based on a Multi-IMSI (International Mobile Subscriber Identity) technology, Sigflow leverages our regional and local carrier partners’ prices to be used on one single SIM card, as a local, anywhere you need. Our SMART SIM card is agnostic to the device you use and does not require any configuration.

Our fully redundant global IP network, with a scalable and robust core carrier network, will make sure you get the highest internet service availability. Not to mention, the lowest latency across 210 countries and 600+ mobile carrier networks. If it’s 3G or LTE, we will dynamically find the best available network for your application.

The Sigflow SIM comes in any form factor or size you choose, including eSIM. This technology allows companies to seamlessly deploy data plans across their user base, optimize connectivity cost and fully manage different subscribers in real-time.

As an innovative mobile carrier, Sigflow provides an unmatched enterprise grade solution for Fortune 500 & IoT/M2M companies, as well as an embedded solution for various manufacturers across the globe, to ensure a secure and continuous internet connection for all devices, no matter where they are in the world.

What is eSIM vs. eUICC?

Multiple International Mobile Subscriber Identities

Even if you don’t consider yourself to be a “techie,” you may have heard of an eSIM card, also known as an eSIM (Subscriber Identity Module) card. Mobile technology is quickly being transformed with the arrival of eSIM cards. With each forward step of technology, wearable gadgets, smart appliances, and many data-sensor applications tend to decrease in size. Commonly referred to as the Internet of Things (IoT), these devices, although getting smaller and smaller, still have to reach a standard processing capacity as well as execute a variety of functions. With the employment of eSIM cards, this is more than possible. In the form of re-programmable SIMs, these cards grant the device owner the capability to compare networks and select them, all directly from the gadget.

eSIM and eUICC together create an embedded architecture that may be securely downloaded and permanently embedded inside any type of device, allowing the device to choose which network to use at any given point. As a result, remote provisioning is possible and much smaller devices can be supported.

Why should today’s consumers care about eSIM?

eSIM has several positive features for consumers, and if your next device supports eSIM, it will be helpful to have a hint of background knowledge about it, so you can get the most out of this technology. Unlike traditional SIM cards, eSIM cards won’t need to (or be able to) be removed from the device in which they are located. The eSIM card is an extraordinarily small piece of hardware, approximately the size of an adult’s pinky fingernail. For compact gadgets, like smart watches, which don’t have the space for a traditional SIM card, this is more than perfect.

Because the eSIM technology is not removable, the idea is that the device owner will be able to switch operators without the added hassle of changing SIM cards. With just one phone call, eSIM technology gives the device owner the freedom to switch to a new carrier quickly. All necessary information is transferred via software in the blink of an eye.
