In today’s article, 24h Technology will help you understand what an eSIM is, its advantages and disadvantages. Specifically, we’ll answer the question many of you have: What is an eSIM? Should I use an eSIM on my iPhone? Hopefully, after reading this article, you’ll have a better understanding of eSIMs and a more positive view of them.
What is an eSIM?
An eSIM is a type of electronic SIM card that replaces traditional physical SIM cards. eSIMs have all the functionalities of a physical SIM but are much smaller (in the form of a microchip) and are integrated into the electronic circuit inside a smartphone, including iPhones.
Because the eSIM is soldered directly to the device’s circuit board during manufacturing, the smartphone doesn’t need a traditional physical SIM slot, making it impossible to quickly remove, swap, or exchange SIMs like with a physical SIM.
Advantages of eSIMs
The first advantage of eSIMs is convenience. They reduce the space required on the motherboard, allowing for more internal space in devices. Using an eSIM eliminates the need to remove and insert physical SIM cards, reducing dust and debris inside the device. Furthermore, removing the SIM slot makes the smartphone more water-resistant.
You can integrate up to five phone numbers into one eSIM, although only one number can be used for communication at a time. eSIMs are helpful in case of loss or theft, as you won’t have to worry about someone removing a physical SIM card and making your iPhone untraceable.
Therefore, eSIMs are considered an integral part of modern smartphones, especially Apple iPhones, offering many practical benefits.
Disadvantages of eSIMs
While the advantages of eSIMs are undeniable, they still have some limitations that affect users.
Most users are accustomed to traditional physical SIM cards, so adopting a new technology like eSIM can be challenging and complex. Users need to understand how to use eSIMs on iPhones and how to register eSIMs with different carriers.
When you buy a new device, you can easily transfer your physical SIM card from your old device. With eSIMs, because they’re soldered directly to the device’s circuit board, you have to contact your carrier or go to a store that can do it for you.
Additionally, transferring data from an eSIM relies on online services to transmit information like contacts and messages. This requires an internet connection.
Should I use an eSIM on my iPhone? Or stick with a physical SIM?
Currently, to use an eSIM in the US, you must have an iPhone 11 or later and iOS 12.1 or later.
In iPhones, eSIMs and physical SIMs use the same mobile network profile; theoretically, the service quality is the same.
Thus, eSIMs and physical SIMs offer comparable signal quality. eSIMs have the advantage of being less prone to damage and can accommodate multiple phone numbers. On the other hand, physical SIMs are more convenient for switching between devices in emergencies.
Considering all the factors, whether or not you should use an eSIM on your iPhone depends on your needs and daily usage.
If you prefer the ability to integrate multiple numbers into a single SIM and quickly change carriers, an eSIM is a smart choice. Conversely, if you want to easily transfer SIM cards between devices, a physical SIM is more suitable.
Conclusion
I hope that after reading this article, you can make an informed decision between eSIMs and traditional SIMs for your iPhone and answer the question of what an eSIM is and whether you should use one.
