What are the advantages and disadvantages of eSIM?
Everyone with a mobile phone knows what a SIM card is – as it is an integral part of the phones that make them functional. Most people, however, don’t know that SIM stands for Subscriber Identity Module and holds various information such as mobile number contacts. The SIM card also allows the subscriber to make and receive calls and text messages and enables the phone to receive data packets from the network.
However, phone companies are now also utilizing an eSIM or an embedded SIM, a small chip inside your phone that acts like a conventional SIM. Among the differences is the eSIM is rewritable, making it easier to change networks. These eSIMs are also considered virtual SIM cards as they are digital versions of plastic SIM cards. This help identifies your device to ensure you have the necessary network connections to make and receive calls and messages. They are also remotely programmable via the right software.
If you’re wondering about the pros and cons of using an eSIM, we’ve enumerated them for you.
Pros: Low chance of losing an eSIM
One of the more obvious advantages of an eSIM is that they’re embedded in your phone. This makes eSIMs safe. You wouldn’t worry about losing the card unless you lose the mobile phone altogether. We all know that when your SIM card becomes damaged, it affects the signal making it difficult to communicate with others. You’ll have a difficult time making and receiving calls and text messages.
Cons: Users are easier to track
Since eSIMs are embedded in phones, privacy can be an issue as users can easily be tracked. Conventional SIM users can remove their SIMs from their devices and be free from anyone tracking them through their phones. However, those with eSIMs don’t have the luxury as they cannot easily remove the SIM without damaging the phone.
Pros: Faster network switching
Doesn’t it annoy you when your phone doesn’t have a signal? With an eSIM, you can easily switch networks with a phone call or through an online application. An eSIM can also store five virtual SIM cards making it more convenient to change networks, especially when you find yourself in a locale where your usual service provider doesn’t have a strong signal.
Cons: Potential costs
As of now, only the top-of-the-line phone models have an eSIM. So if you want a mobile with an eSIM, you might have to shell out for a new plan. Granted, it will provide more comfort and features, but the cost can be prohibitive for some higher-end phones.
Pros: Allows more than one number on the device
One of the biggest advantages of using an eSIM is having multiple numbers on your phone or device. This is good, especially if you want a number for your business and another for personal use.
Cons: Potential security risk
As eSIM is a software-driven technology, it can be more vulnerable to hacking. In addition, since data are on servers or the cloud, they’re prone to security threats.
eSIMs are in the spotlight nowadays because of their advantages. However, mobile phone users must also be wary of their disadvantages.
