eSIM and 5G - The Future of Wireless

With the recent announcement of Apple’s iPhone 12 making the jump to 5G connectivity along with a range of other features like eSIM, this further hammer down cellular data platforms in 2020. Nowadays, all smartphones include wireless capabilities that are shifting even further towards hardware changes to supplement faster and better connectivity. The potential of wireless data with 5G seems to be paving the way for a new cohort of web and mobile applications and use cases.

eSIMs are an additional hardware advancement that is defining the future of connectivity. With the potential for improved service delivery, data roaming, multiple mobile plans, and business functions, eSIM technologies are shaping the future of cellular communications. Now that almost all flagship models of the top smartphone producers have produced 5G and eSIM ready phones, the next generation of super connectivity will start to take place.

eSIM Technologies and 5G Networks

In some cases, a person’s phone might have a cellular data service that is much faster than what they have at home. 5G is projected to have a download speed of up to 1 Gigabit per second, with split-milliseconds in latency speeds. Nowadays, most new devices are ready for this new network, but it is up to local providers’ infrastructure and data roaming powers to make such service available. Fortunately, various companies are investing hundreds of billions of dollars into boosting the fields of 5G wireless connectivity.

5G and its associated devices will mean that the old SIM cards will either need to optimize and update or risk losing out to eSIM technologies. Historically we have seen significant changes and improvements in the SIM card, presently in the nano-SIM form, but it is slowly regarded as impractical. With the hardware fixed to use more digital functions, there is much more potential for the Internet of Things (IoT) to work through various eSIM devices.

The Full Range of Use With eSIMs and 5G

While eSIMs are a permanently embedded chip that goes into smartphones and wearable devices, eSIMs are in many aspects much better than SIM cards. This hardware piece is rewritable, highly secure, compliant with authentication of operators and telecommunications companies and have ease of access and remote management.

eSIM underlying technologies share functionalities with their predecessors. However, as networks start to become more powerful, the hardware and software requirements equally require optimization. While the traditional SIM might still work well for 5G capabilities, the other benefits of using an embedded SIM far outweigh the physical version especially when it comes to digital delivery and activation. Also traveling to 5G capable countries will be easier using cellular data platforms, as roaming becomes an easy setup via a quick activation procedure.

Businesses with assets worldwide can benefit from eSIM technologies, as various networks globally can all stay connected using the global system for mobile communications (GSM). GSM’s connectivity aspect makes having the eSIM’s functionality better because of the uniform method of contacting various entities across various borders. Without needing modified phone models to stay in touch or requiring expensive call and text plans, global data on the 5G scale will improve business operations.


eSIMs are the future of connectivity, and whether it is for calling and texting or global data, they have unparalleled power. Now that 5G is in the mix, the faster speeds will require an equally advanced cellular data platform to support it, which can be best delivered via eSIM programming.

CELITECH works to provide eSIM cellular data to businesses via web applications and API development. With wireless data being the future of both consumer and business applications, making the jump to newer technologies is the way to go.
