The SIM in the word ‘SIM card’ is a reference to’subscriber identity module. The tiny plastic chips store the information you need for your phone like your number, contacts pictures and messages. For a while, it was the sole method for your mobile to be connected to your mobile network in order to send texts and calls. But more phone suppliers are now shipping phones with eSIMs, including the first handset with a 5G standalone-compatible eSIM Europe, suggesting that some time soon most new handsets will support eSIM technology, if not as a replacement to SIM cards, as an additional SIM option.
What exactly is an eSIM?
An eSIM, also known as an embedded SIM can replace the requirement for the physical SIM card. It’s basically the electronic SIM card that’s embedded in your phone at the time of the phone’s production. Utilizing an eSIM can have advantages and disadvantages. Let’s take a look at some:
The advantages of the use of an electronic SIM
You may have more than one number
As with phones that has dual SIM card slots, using an eSIM allows you to have several phone numbers. The primary benefit is that you can make and receive calls as well as texts from either phone, meaning you’ll be able to manage your outgoing and incoming communications.
They are extremely useful in the separation of work and personal emails. You can also utilize an eSIM along with physically SIM card, and they permit you to customize your connection across all of your devices.
They are much easier to be activated than SIM cards.
Even though physical SIM cards have to be placed into your smartphone to activate this is a process that often requires the hand-strength of surgeons or a surgeon, an eSIM can be activated just through scanning the QR code which is registered to your eSIM profile on any mobile phone network. Certain networks might require that you enter an identification number. In the majority of cases, you can connect on your networks in not greater than 15 mins.
They make switching service providers much easier
The phone you have with an eSIM enables you to change networks more quickly, as it eliminates the need to purchase an entirely fresh plastic SIM card. This means you don’t have to visit the retailer for your network or waiting for the card to arrive via post. With an eSIM on your phone, you can select the service provider you want to use and link to the network from a remote location by obtaining the data required to connect either over the phone or via internet.
You don’t need to deactivate accounts permanently
eSIMs are able to store multiple profiles, which means you can switch between networks without needing to disable your accounts permanently. This is particularly useful for those who travel, as it allows you to connect to the internet wherever you travel. It’s also a generally more economical option to activate global roaming.
They consume less space inside smartphones.
The Nano SIMs are the current cards used in the majority of modern smartphones. The tiny cards measure around 8.8mm and eSIMS measures only 4 millimeters. This smaller size lets that phone makers have more room to add additional features such as more battery capacity or to increase the performance of phones by utilizing a more powerful processor. Additionally, it allows them to increase the phone’s IP rating against dust and water because the absence of an SIM card slot implies that there are fewer entry points.
The disadvantages of using an electronic SIM
It is more difficult to repair in a brand new phone.
If your phone gets damaged or breaks, your small plastic SIM which was hidden in your phone will be pretty unharmed. It is easy to take it out and put it into a new device however this isn’t the case for an electronic SIM. It is necessary to retrieve the eSIM account from the cloud. This can be much more laborious to complete. It can also take longer than what it takes to move your profile into the new device in the event of an upgrade.
Users can be easily tracked by networks
People who are concerned about privacy can stop their mobile phone’s network from following their location by disabling the physically SIM card. But, because eSIMs aren’t able to be removed and are permanently connected to phones, eSIM user’s phones will remain connected to their provider’s network, making them more easily tracked. While this shouldn’t be an issue for the majority of people in countries like Australia however, in other parts of the world, this might be a huge issue especially for people belonging to groups who are targeted by their government.
Hacking
In terms of security, eSIMs are generally very secure in that they cannot be removed physically and put on other devices by thieves and can be programmed to ask for confirmation from operators every time anyone attempts to alter an account. However, they’re not completely secure from fraud, as hackers will often go to extreme measures to penetrate vulnerable mobile carrier systems to steal personal information or profiles of users.

The latest Apple iPhones, such as iPhone 13 series, and the iPhone 13 series and iPhone SE (3rd Gen) come with eSIMs, as does Samsung’s most recent Galaxy S22 series devices. The phones that have eSIMs are:
