Modern smartphone models allow users to use electronic SIM (Subscriber Identity Module) cards and physical SIM cards. And some developers have entirely abandoned the Nano SIM card slot and completely transferred their devices to eSIM.
This technology, presented for the first time on the market in 2019, can be called evolutionary. Indeed, from year to year, developers have reduced the size of SIM cards from Mini Sim to Micro Sim and then to Nano SIM, freeing up more space for other components. The introduction of embedded SIM naturally ended this fight for every millimeter. We propose to find out whether a gadget with a new type of connectivity to cellular communications is suitable and what advantages the new type of smart cards has.
What is eSIM?
Unlike a traditional SIM card, an electronic one cannot be held in your hand because it is not framed in a plastic case and is not inserted into a special slot. Generally speaking, eSIM is the same “SIM” but physically soldered on the motherboard of a smartphone. The letter E of the Latin alphabet means embedded – “built-in.”
This is not just a programmable SIM or subscriber number. An e-SIM is a module like Bluetooth or NFC. It has its own processor, memory, controller, and operating system.
eSIM on smartphones
Some users are not sure if smartphones with eSIM are suitable for use and if there will be additional difficulties due to the new type of SIM card.
Do not worry: eSIM is not a difficulty but an additional opportunity for owners of mobile devices that support the technology. For example, to activate the card and change the number, you do not need to go to the office of the mobile operator – you can apply for an eSIM online at the esimway.com. Once you connect a digital SIM card, you can enjoy the benefits and opportunities for many years without any difficulties.
As usual, flagship models are first equipped with new developments. The list of gadgets that support the electronic analog of a SIM card includes some models from Apple, Huawei, and Samsung.
eSIM Benefits
Since the card module is soldered into the “stuffing” of the gadget, it cannot be lost or forgotten somewhere, damaged, incorrectly inserted, or broken. No need to store; look for a paperclip to remove the slot – eSIM owners do not need to look inside the mobile device at all. In addition, a digital SIM card is a more environmentally friendly option compared to a physical one since it does not use plastic for its production.
Unlike the plastic ones we are used to, the new type of cards allows you to rewrite the data about the number and operator as many times as you like if the user wants to change them. For owners of cellular devices with support for one physical card, connecting an eSIM is an opportunity to link personal and corporate numbers to a gadget, for example. You can register numbers with different data plans on one eSIM card – for example, with unlimited internet, advantageous calls, and a number of a foreign operator for travel. Physical card and eSIM can work at the same time.
Switching between numbers and operators is simple and fast. Adding and removing them from the built-in SIM card is easy online in a few minutes. It also quickly deletes unused numbers.
You can apply for an eSIM at any mobile network operator. Having received a voucher with a QR code, you just need to add the card to your smartphone by scanning it. To download a new smartphone, you must remove the eSIM from the previous one.
When changing a smartphone, one can delete a profile from one gadget and register it on a new one. If the code is lost, you can restore it.
When the smartphone is lost or stolen, the card and the associated numbers can be blocked by calling the operator, just like a regular SIM card. After that, you can activate your old number on another device by scanning the QR code. Several gadgets supporting the technology can be linked to one number simultaneously: smartwatches, tablets, and others.
Conclusion
Switching to eSIM is an intelligent move for owners of smartphones equipped with a built-in module. The electronic analog perfectly replaces the classic SIM card, eliminating the need to manipulate the smartphone to change the number. In addition, you can use one device worldwide by switching to a favorable tariff.
Judging by the number of advantages of the new format, this type of connection to cellular communications will gradually replace physical SIM cards. The owners of such smartphones have the opportunity to be one step ahead.
