eSIM and iSIM chips that will be included in phones in the future What are they and how do they differ from one another?
Everything suggests that eSIM and iSIM will be the most widely used SIM cards in the future, even though the great majority of mobile phones still use traditional SIM cards today. Through their integration into mobile phones, these two technologies aim to replace SIM cards. You are undoubtedly already familiar with eSIMs because we have already discussed them with you.
Given that iSIM is a more recent technology, it is highly likely that you are unaware of what it is and how it varies from eSIM. In fact, there are no phones on the market with iSIM: Vodafone and Qualcomm are testing it in Europe. So, before carriers start using it, we’ll see what this technology looks like and how it differs from eSIM.
eSIM and iSIM are not cards that you can insert and remove from your phone like SIM cards. They are technologies built into phones that securely store your phone number and access codes with your phone carrier.
Both eSIM and iSIM are permanently embedded inside the phone, saving space and making the phones lighter and thinner. Both eSIM and iSIM are configurable: they let you choose the carriers you want and switch your phone number to another carrier at will, without having to buy a SIM card.
Any changes you want to make to your line can be made over the mobile network rather than physically changing the SIM. Obviously, this can only be done by the carriers. But the best thing about eSIMs and iSIMs is that they can be used to use the same phone with multiple carriers, making international roaming much simpler.
In the future, it should be possible to manage credentials and access multiple devices using an eSIM or iSIM using a single charge. This applies to both the business world and the consumer world.
- All the differences between eSIM and iSIM
The main difference between eSIM and iSIM lies in their implementation. While eSIM is a dedicated chip soldered into the mobile processor, iSIM is integrated into the processor (or rather, SoC). This means that iSIM does not take up any extra space inside smartphones. On the other hand, eSIM takes up some space (although not much).
The difference may be subtle, but it is important for security purposes. iSIM is primarily designed for Internet of Things (IoT) devices due to the enhanced security provided by integrating the SIM card into the SoC. Devices are tamper-proof using external nano SIMs or eSIMs and take advantage of the tamper-proof SoC offered by ARM-based chips. This makes it virtually impossible to exploit the network hardware or software.
In short, iSIM is an eSIM that takes up less space and has better security. In addition, since they are integrated into SoCs (chips that include the CPU, GPU, and other components needed to power the hardware), iSIMs allow the mobile phone to be brought to more devices: virtual reality or augmented reality glasses, wearables, etc. Anyway, we hope this explanation was useful to you.
