What Is eSIM? What Are Its Benefits?

Embedded SIM or eSIM allows consumers to activate their cellular plans without the need for any physical SIM card. However, the majority of cellphones don’t support eSIM, but soon every phone manufacturer will remove the SIM slot. 

What is eSIM?

It is an inbuilt small silicon chip that works like the NFC chip used for online payment tech – Google Pay. Its size is too thin [2.5 mm by 2.3 mm]….it has 60X less volume than nano-SIM [8.8mm by 12.3 mm]

With just a phone call you can switch your operator. It means eSIM information is rewriteable. It is also compatible with leading carriers. You can easily add a data plan connecting smart product with eSIMs to a mobile account. eSIMs specifications are standardized for interoperability and enabling remote wireless data SIM provision to any type of cellphone. 

eSIM is applied in consumer products like computers, wearables, and smartphones. Besides, you will find them in medical IoT, smart meters, connected cars, smart security systems, IoT asset tracking devices, portable POS systems, etc.

What are the benefits of eSIM?

The onboarding experience for end-users is simple. The eSIM API allows electronic devices to be used instantly, the moment they get switched ON. Changing operators is effortless because eSIM is rewritable……involves just a phone call! 

End users also don’t have to handle the cutting of SIM cards or searching for adapters. Apple phone users get Dual SIM options, which can better their experience. 

With dual SIMs and eSIMs, you can choose two different carriers – One for business and the other for personal calls. When you travel abroad add a local data plan. Regular travelers can enjoy eSIMs because it eliminates foreign roaming charges. 

It is extending on-the-go connectivity for multiple new connected devices as well as opening doors for new business opportunities.

Support and logistics are simplified. There is no need for managing physical SIM cards at the customer level. 

They can design new devices that are smaller because removing a physical SIM card slot saves a lot of space. In mobile devices, every small bit account for space. Physical SIM card needs a housing, tray, and reader. 

Removing the slot and opening decreases the possibility of mobiles getting compromised wit dust or water. All this means designers can design tiny devices with more resistance to dust and water. 

Are there disadvantages to eSIM?

How eSIM improves connectivity?

Celitech offers wireless programmable cellular data API through QR codes. Developers can easily create eSIM API for apps that can help online businesses engage better with consumers and the end-users. Technology is creating an evolution in the model of a connected lifestyle. 

We are progressing from simple mobility solutions to hyper-connectivity with IoT [Internet of Things]. There is an exponential growth in connected devices, so it has become essential to understand the SIM connectivity technology.
