Esim (eUICC) for iot - esim cards | Legacy iot

Esim(eUICC) or Embedded Sims

Embedded eSim, or we can say a nano chip that is already installed in phones and device's motherboards. It is smaller at 6 mm in length and 5 mm in width. ESims is a non-removal Sim, and their required data are stored in a personal ESim profile.


The ESim stands for embedded universal integrated circuit card and is also known as iSims or eUICC card. In Simple terms, we can say. It's just a chip directly inside your smartphone right from the manufacturing process. It doesn't require any physical card like M2M Sim Cards or Standard SIM Cards, and you can add or remove operators at will, where you can change the company's networks at any time.


Legacy Networks ESim is suitable for a wide range of applications, including high-performance non-standable & standable 5g, low-speed NB-loT & high performance. They can be assigned to multiple operators, and the eSim profile can be transferred over the air to the device.



The eSIM is, in fact, a substitute for an actual physical plastic SIM card. If your smartphone supports it, you'll only need to add your SIM profile to your phone, and it's the same as having a standard Sim with just no card.


So the main difference between the eSIM and the standard SIM card is that now you don't have a physical Sim to worry about; it only re-programmable logical profile on your smartphone.


A regular SIM card holds one profile for the customer, but an ESIM enables multiple profiles for the customer, which is a better advantage. Also, there's the fact that technology is evolving, and now, with an ESIM, you have your SIM profile on things like smart watches, cars, and computers. It's just better, and with the same ESIM profile, you can enable it to work on multiple devices; this is not the same for a regular plastic physical SIM. It's just one Sim and one machine, a phone.


To get a standard SIM, you must go and physically buy a plastic card to join the network; that card will, of course, only work with your one device. With Legacy Networks ESIM, you'll only need to get your ESIM activation voucher linked with your existing profile or the new one you have created, scan a QR code, download your profile and install it on any of your supported devices, and you're done. Of course, you'll have to register it.
