- One of the many benefits using an eSIM is convenience of switching to preferred network operators or eSIM provider without swapping for the traditional or physical SIM card.
- Although it offers better security and can be reprogrammed, eSIM couldn’t be removed physically from a device whereas it can be hacked using cloud hosting technology.
With each passing year, technology gets more innovative, modern and better in every way. The same is the case with mobile SIM cards as the traditional ones are soon to become history and replaced by a virtual edition. Still, not all the new technologies that arrive are flawless, including these eSIMs. Let us first understand what is an eSIM, followed by its pros and cons.
An embedded SIM or eSIM in short was formally termed as an embedded Universal Integrated Circuit Card (eUICC). It’s a small microchip directly attached to a mobile or telecommunication device’s motherboard during the production/manufacturing phase whereas functionality is the same as that of a removable SIM card.
Likewise, an eSIM is a small chip that works similarly to NFC chip however with an advantage of remote provisioning features that enhances overall customers’ user experience at the time of management and activation of the mobile devices. A user can then select preferred mobile operator from the phone settings as well as most suitable plan.
One of the many benefits using an eSIM is convenience of switching to preferred network operators or eSIM provider without swapping for the traditional or physical SIM card. It removes the hassle of constantly swapping SIM cards, network carriers and even keeping multiple phones for different purposes. That said, international travellers are relieved from visiting a local telecommunication office just to purchase a new SIM when overseas as they can modify the setting directly through the eSIM.
- Coming Soon.
Devices that support eSIM come without a SIM tray as they don’t need one which further allow manufacturers to design better and innovative smartphones, water resistance features with additional space.
Cost effectiveness is yet another added benefit. Think of all the roaming charges you can save when traveling abroad alongside the opportunity to call, text and even browse mobile internet on local charges. Service operators are likely to accommodate new offers for vacationers as well as local users.
Instead of purchasing two different SIM cards or mobile phones, the new eSIM allow using more than two numbers on a single device. Users can also keep corporate and personal contacts separate having dual numbers on one SIM with the option to shut down any of the preferred number outside the business hours.
Last but not the least, having an eSIM reduces the risk of a lost or damaged SIM card. In more extreme situations such as phone theft, eSIM couldn’t be extracted at all allowing user to track the phone and retain the data.
Much like every other technology, there are certain drawbacks of an eSIM as well. Although it offers better security and can be reprogrammed, eSIM couldn’t be removed physically from a device whereas it can be hacked using cloud hosting technology.
Transferring eSIM to another smartphone in-case the first one breaks is yet another challenge. In such a situation, traditional SIM cards can be physically removed from the tray and inserted in a new set bit this isn’t possible if the device is an eSIM manufactured. The process to extract data and have the SIM functional again takes time.
eSIMs are surely to replace the traditional SIM cards on almost all devices which is why getting acquainted with the technology and all its factors, be it good or bad, is beneficial for users.
