Pros & Cons of Using eSIMs

SIM cards have been a staple of mobile technology for more than 30 years. In the past decade, SIM cards as we know them have begun to be replaced by a similar counterpart known as eSIMs. Rather than having to keep multiple SIM cards for each profile or number, an eSIM can handle it all with just one piece of hardware.
Major mobile providers like Apple and Samsung have already begun including eSIMs in their mobile devices. If you are unfamiliar with them, eSIMs offer a number of benefits to those who use them.
What is an eSIM?
An eSIM stands for ‘embedded subscriber identity module’ and is a variant of the more traditional SIM card. The beautiful thing is that a European eSIM works in the same way as a North American eSIM in its fundamentals. Rather than using a removable plastic card, your phone uses an embedded SIM that can’t be removed.
It used to be that users would change out their SIM card at times when travelling in order to set up roaming or utilise a different phone number. The information within the eSIM is rewritable, meaning you can change networks without having to change the SIM card. Multiple profiles and numbers can be stored on a single eSIM, making them far more versatile.
The Pros of Using an eSIM
There is a lot to like about using eSIMs. There are four primary benefits to be had to using a device that has an embedded SIM card built right in.
More than one SIM. It used to be that you required several SIM cards if you wanted to switch out profiles or phone numbers. The beauty of an eSIM is that you can have more than one SIM on any device without the hassle of switching out SIM cards. If you carry a number for personal use and one for business, you won’t have to carry around two devices.
Less physical space. Physical SIM cards (and their trays) take up space and aren’t great for the environment. By switching to eSIMs, there is more room for features or a larger battery rather than having to devote it to the SIM card. Fewer holes in the device also means being able to keep it better protected from dust and moisture.
Easier to switch networks. The true beauty of using an eSIM is being able to switch mobile networks. Rather than having to order a new SIM, waiting for it to arrive, then having to insert and set it up, you can just switch to a different network right there on your device or through any browser. There is no need to eject old SIMs either, which can be a major pain.
Make temporary network changes. eSIMs can store up to five virtual SIM cards. Switch between networks quickly, which is great for travelling. Using a local mobile network can be far cheaper than having to pay for roaming costs.
The Cons of Using an eSIM
Though there are many upsides to using eSIMs, there are a couple of downsides to be aware of as well.
Hard to switch devices. Should your phone stop working, you can’t remove an eSIM. All the information is on the cloud, so it isn’t hugely inconvenient to move over contacts, but it is never as easy as we hope it to be.
Can’t remove them. Since you can’t remove an eSIM, there are concerns about tracking. If you feel like your phone is being monitored in a way you don’t feel comfortable with, you won’t be able to simply change SIM cards.
