In the future, when we commemorate Apple Watch 3, don't forget it is because it's Esim technology will be popular.
As we all know, the phone is inseparable from the SIM card. If you do not have a SIM card, there is no activation of the SIM card, the phone and iPod have nothing too much. You can pick up your phone to connect to Wi-Fi, Bluetooth, but there is no way to connect to the operator's mobile network.
ESIM technology can replace SIM cards, which is just a small circuit that can repeat programming, circuit implant, tablets, watches, and other smart devices, and then download the program and select the operator. There is no need to open the cover or pop up the Catto, there is no need to put the card into the phone.
Compared with the SIM card, ESIM has some advantages and some shortcomings. First, the advantages, ESIM will not take up space. Even the NANO-SIM card is too big for some small devices (such as smart watch). Some watches are very high, to find a space to place cards and Carto is a trouble. Because of this, Samsung 2016 Gear S2 Classic 3G smart watch will introduce ESIM technology.
Esim also has an advantage: improve the waterproofing capacity of the equipment. The phone, the tablet Carto can indeed isolate the internal components so that water will not enter the body through the calorie, but the card itself will remain influent and affect performance. How do you not let the water influence? It is best to remove the calorie, so the waterproof capability of the equipment will last.
Can connect to any network at any time
You don't have to bring your SIM card for your mobile phone, you will have a great convenience to users, this is the biggest advantage of ESIM. That's right, big brands have been stationed in mobile phone stores, supermarkets, convenience stores, users are very convenient, but they go to the ESIM era, whether it is day or night, users can use any brand of products on any network.
Users don't even need to download the operator setup program with Wi-Fi. Every ESIM will be programmed in advance, and you can connect to the operator's service through a variety of cellular networks. Download the full soft SIM card.
From a competitive point of view, if you can easily replace operators, you can not stimulate competition.
In the early stage of the moving age, if you want to change the network, you must give up the current mobile phone number; regardless of other operators' package more attractive, business customers are reluctant to give up the number. No one is willing to replace the SIM card, if it is ESIM, there will be such troubles.
When we go overseas travel, if you want to use overseas networks, there is no need to queue in front of the airport service desk, nor is therefore necessary to change the card.
Is the SIM card really a place? no. It can store operators set information, rugged, and very reliable. As long as you look at it, we can replace the network at will.
Is it really easy to change the soft SIM card? Or let the time tell us answer. One day, if you arrive at the Los Angeles International Airport, you find your own mobile phone that cannot be connected to the operator's network for a reason, it is definitely a trouble.
Big companies are promoting ESIM
As early as many years, the ESIM card that can be repeatedly written has already appeared, and Apple has also developed a dedicated soft SIM card, put it into the iPad, and is launched in some markets.
In 2015, Samsung, LG, Microsoft, Huawei and other manufacturers have aggravated the network operators, agree to establish a set of industry standards, clear the road for ESIM, because so, Samsung launched an ESIM smart watch last year. Later, Apple participated in and let more people know soft SIM card, which puts ESIM in the watch and let more people use it.
A few days ago, Google launched a new smartphone Pixel 2 and Pixel 2 XL, where Pixel 2 used ESIM technology. Although operators "point their heads" in terms of standards, not all operators have deployed. Because the supported mobile network is limited, PILXE 2 is still equipped with NANO-SIM Cardo.
The volume of the mobile phone is still relatively large, and two options can be provided at the same time (that is, ESIM and SIM), but the industry is moving towards the phase-out SIM.
The more software features, the more flexible system. Australian mobile operators have modified the background to allow iPhone to share a mobile phone number with Apple Watch.
