What is eSIM
eSIM card, also known as embedded SIM card, simply put the traditional SIM card embedded directly on the device chip, rather than as a separate removable components to join the device, the user does not need to insert the physical SIM card as now.
Traditional Sim cards lock users in a service network, and embedded SIM cards can make smart phone, tablet or wearable device users to avoid confining to one operator's service, which can be achieved immediately switch to other service networks , And do not need to change Sim card.
The emergence of eSIM means that only the use of mobile phones for Internet access, voice calls era is coming to an end.Will be more wearable smart devices to achieve functional independence, Internet and telephone voice will no longer be exclusive.
The popularization of eSIM will also gradually replace the existence of mobile phone entity SIM card, users can achieve the freedom of switching operator's convenience will also be just around the corner. Sudden shift of mobile, China Unicom, telecommunications operators will be transformed into Terminal Services Business
eSIM technology will replace SIM card
The key to eSIM's ability to thrive stems from several core features of eSIM technology:
1. It does not occupy space, because it is embedded in the device during the manufacturing process, it can save more space than the physical card eSIM card. 2. It can adapt to abnormally harsh environment, and compared with the way of device integration. The traditional SIM card can withstand high temperature, dust, and shock, with wider application of electrical characteristics; 3, flexibility, flexible choice of operator network, OTA over-the-air download dynamic write user subscription information, can achieve product sales After the user autonomous activation; 4, eSIM based on the security domain architecture and the introduction of PKI security infrastructure, providing a higher level of security.
With eSIM technology becoming more and more mature in the past two years, it has gradually been applied to more and more fields.
Once upon a time, Apple Watch was just a smartwatch that needed to be connected to the iPhone's Bluetooth to make calls, etc. Once you left the phone, Watch was a smartwatch.
With eSIM, Apple Watch enables stand-alone calling without the need to connect to an iPhone for Bluetooth.
In addition to Apple, Samsung, Huawei and other technology giants have been developing corresponding smart products for eSIM.
Meanwhile, a study by Mücke, Sturm & Company, a market research firm, said market penetration of eSIM cards will reach 50% by 2022 worldwide.
In a few years, you may really want to say goodbye to the SIM card.
Is eSIM the carrier's doom?
After using the eSIM card, how do users use it?
Very simple, open the phone, through the eSIM built-in application, select the operator, number, package, etc., determine, these packages, the number is written into this chip, you can use the phone. If you feel uncomfortable, feel free to use You can choose a new operator, do not have to go to the business hall for withdrawal.
For operators, how much impact?
Cost savings, no physical cards, no need for too many people to make cards, write cards, etc. Everything can be operated on the internet. But for operators, the headache is that the cost for users to change numbers is relatively low, and there is no need to run business halls. Etc., it is easier to compare the preferential treatment of various operators and increase competition.
Moreover, the number portability in foreign countries where the mobile operators will be more competition, see you unhappy, directly for the operator for a set meal.
For our ordinary users, or first look forward to China can bring portability number, so that operators lying down to make money will be gone!
