Comparison between e-SIM card and SIM card

What is e-SIM card?

As we all know, "SIM" is the full name of "subscriber identity module", that is, "user identity module ". It is mainly used to store data, including some fixed data.

Speaking of E-SIM cards, you must first understand these:

As early as March last October, Apple built an "Apple SIM card" in the new 4G version of iPad Air 2. In the United States, using this Apple SIM card can free the iPad from the trouble of switching carriers. The e-SIM card is a follow-up product of the Apple SIM card.

Now Apple and Samsung both "turn the enemy into friends" and want to implement this e-SIM card together. At present, many carriers in foreign countries have already supported the development of e-SIM cards, but a small number of carriers do not yet support it, and it may be even more late to implement e-SIM cards in China.

The e-SIM card that Apple and Samsung want to launch will be integrated into their mobile phones, and users cannot disassemble it themselves. However, the user's identity recognition module allows them to select a carrier based on their own needs, and allows users to switch anytime. Simply put, the current "small paper" SIM card is virtualized. This new e-SIM card standard may become a new standard for iPhone and Android.

E-SIM card strictly speaking is not really a virtual SIM card. The main significance of it is that if the use of E-SIM card equipment, then the user no longer need to buy the device after their own plug-in card, instead, you can directly use your own carrier network and package through software registration or direct purchase.

After e-SIM is implemented, the e-SIM card is pre-installed on the device when the mobile phone leaves the factory. It does not lock the network of a certain carrier. You can switch the carrier service through the system interface, at the same time, you do not need to take out or replace the SIM card.

E-SIM is also an important benefit for mobile phone manufacturers because SIM card slots are not required, so they (mobile phone manufacturers such as Apple and Samsung) can design thinner and thinner devices. Maybe in the early stage of e-SIM implementation, the entity card will still exist, but when the e-SIM standard is formally set up, the entity SIM card will gradually be forgotten over time.

At present, many operators support the development of e-SIM technology, including AT&T, Deutsche Telekom (T-Mobile owner), Vodafone, Spanish telecom and Orange. Apple and Samsung are two major developers implementing the e-SIM standard. Other participating organizations are awaiting confirmation, and the e-SIM standard is expected to be officially released at some time in 2016.

E-SIM card for users is the gospel, but the challenges to operators, support E-SIM card mobile phone, is equivalent to all Netcom, users can switch very conveniently, for some competitive low operators, brings new challenges.

What is the difference between e-SIM card and SIM card?

In the above general understanding of E-SIM card, we have a general understanding of the difference between e-SIM card and ordinary SIM, E-SIM card is equivalent to embedded in the phone, the SIM card is a real card and needs to be installed by the user.

Real SIM cards are classified into standard SIM cards, small SIM cards, and mini SIM cards.

It is worth mentioning that the logic of the E-SIM card and SIM card is the same, but external, changed to embedded, security has not improved.

We will introduce the difference between e-SIM card and common SIM. Finally, it is worth mentioning that e-sim is also the name of a game. For example, it is a free and online web game made by Poles, but it is rarely known to everyone, generally we say E-SIM card, is Apple and Samsung intend to cooperate to launch the E-SIM mobile phone card.
