The leading American telecomunications firm, Verizon is set to create a SIM Card that runs on Blockchain technology. Dubbed as the virtual subscriber identity modules (vSIMs), the new technology will enable customers to abandon physical SIM Cards and embrace more reliable virtual solutions.
The award of the patent by the U.S Patent and Trademark Office is paving the way for Verizon to push forward with the project.
How The Technology Works
According to official reports, the virtual subscriber identity modules (vSIMs) technology is set to revolutionise the mobile phone industry that is increasingly becoming dynamic. For instance, 10 years ago, no one could project with certainty that smart phones and 4G/5G network could be so common.
In the proposal, Verizon is aiming to replace the physical SIM Card technology with virtual models. The role of Blockchain technology in the arrangement is to power and secure the ecosystem that will be hosting decentralised SIM Card repositories. As is the case in the conventional Blockchain systems, transactions will be secured through encryption.
The Blockchhain technology will also enable the telecommuication services provider to create user accounts for managing vSIMs operations. From these accounts, subscribers will be able to select networks of choice on their devices. Afterward, a signal will be sent to the Blockchain servers. Once the account user is verified, the Blockchain platform will connect the device to the telecominications ecosystem.
Security Is Guaranteed
With new innovations, comes security concerns. In this perspective, virtual SIMs operations that Verizon will deploy are designed to be attack-proof through atuthenittcation codes features. This is because the Blockchain technology will create a unique set of SIMs repository records that are immutable. Consequently, the system will assign vSIMs certificate with an International Mobile Subscriber Identity (IMSI) number to each account user.
To enhance security, participating nodes which are the network participants will be vetted before being allowed to access records and validate transactions. Any account whose IMSI code fails to match the particular code on the virtual SIM records will be denied access.
Summarily, the users’ accounts constitute the virtual sim and can be retrieved, used in accessing telecommunication networks in multiple devices,and assigned to third parties.
The End Of Physical SIM Cards Could Be Nigh
The concept of Virtual SIM cards is not new. However, the Verizon project is set to create a global awareness of the opportunities of Blockchain in this use case. The Basking Ridge, New Jersey-based company is the second largest telecoms firm in the country after AT&T. Therefore, Americans could see increased innovation in this area.
Another similar solution is being offered by WorldSIM that enables clients to log into their devices and access telecommunications services. However, unlike Verizon’s vSIMs, this technology relies on radio or internet to validate users to grant them access to the network.
