It is a common misconception that some technologies are here to stay. It may seem like a certain piece of modern tech cannot be improved upon. SIM cards are thought to be one such piece of tech. Though there have been several upgrades to the SIMs, the basic technology behind them has remained the same – that was until eSIMs came on to the scene.
What Are eSIMs?
eSIMs are not physically inserted into devices, instead, they are embedded as a chip inside devices like phones, tablets, wearables, other gadgets, and even modern home appliances. There are devices that support traditional SIMs as well, but they can perform the function of a SIM card even when a physical SIM card is not available.
Users are able to connect to a specific cellular network through an eSIM on their device. All they need is a device that has a chip built into the device and get a contract from a mobile operator that can support an eSIM.
What Devices Support eSIM?
The list of devices that support eSIMs is growing daily. Almost all flagship smartphones now support eSIMs. Apple, Samsung, Huawei, and most all other phone makers are building eSIM support in their phones. The majority of these devices come with both eSIM and physical SIM support.
Aside from phones, wearable tech like smartwatches also come with eSIM support. Users can make calls without having to connect their devices to a phone.
Tablets and some laptops, which are called ‘Always Connected’, come with eSIM chips soldered onto their motherboards. This way they can remain online at all times, no matter where you are, even in another country or region. With the passing time, IoT is bringing more devices with continuous internet connectivity and in the future, this will be a norm.
What Are eSIMs Used For?
In the simplest terms, an eSIM is a small chip that allows devices to connect to available cellular networks. These SIMs don’t have any moving pieces which makes them more durable. They are low profile and allow IoT devices to connect with a unique ID that allows connection to different network operators. Without having the need to negotiate contracts with every network, you can remain online. This reduces the cost and time for the user, and they can experience constant internet connectivity without any hassle.
Benefits Of eSIMs
eSIMs come with many benefits, some of these are:
- Lack of physical SIMs ensures that eSIMs are protected from weather and other elements that may cause damage to them
- eSIMs allow remote connection
- They are small in size and can fit inside devices like watches
- These SIMs can connect to multiple networks, whichever has the strongest signal
- eSIMs are more secure than traditional SIMs
- They have become mainstream, being adopted by top consumer brands in the tech world
- The convenience they offer means that they are the future and will be available on all devices that require an internet connection
Why Cellular IoT Needs eSIMs?
There are 2 major reasons why eSIMs have become a necessity. The first reason is that traditional SIM cards have to be inserted inside the device, which takes too much space. This is inconvenient for modern wearable and smart devices. There is an open space where the SIM is inserted, which leaves the devices vulnerable to dust, water, and other elements. eSIMs negate all of this.
The second major reason eSIMs are better for IoT devices is the fact that traditional SIMs are locked onto a single cellular operator. This means that when you travel or go to a different location, you will have to pay high data prices that your network provider has negotiated for roaming devices. eSIMs can connect to any available network, the plan is pre-negotiated by service providers so you don’t have to pay heavy prices.
How eSIMs Will Aid Mass-market IoT Development?
eSIMs offer security, interoperability, and flexibility for IoT devices. Consumer brands and industries are fast-tracking the development of IoT devices with eSIM chips.
This affordable chip can allow people to connect with cellular networks and bring down the cost for manufacturers.
Interoperability ensures that users can remain online 24/7. This need for always-on connectivity will drive the development of more devices that support eSIMs because end-users demand it. eSIMs allow for better security on the devices due to modern protocols built-in to them.
