The eSIM was announced by Apple in its special event of 2018, but after all what is this technology that everyone is talking about?
After the introduction of the new iPhone models, many Apple lovers are thinking and trying to draw their own conclusions about what eSIM is. In this article, we will try to clarify all your doubts.
Before we begin our journey in the eSIM world, let’s review the old SIM models and their meaning.
A Brief History of SIM Technology
SIM stands for Subscriber Identity Module and represents the card you place on your smartphone to make and receive calls as well as send messages to your contacts. The old models are: the SIM, the MINI – SIM, the MiCRO – SIM and the NANO – SIM.
What is eSIM?
ESIM is not new. The idea of this virtual card is to bring a chip that is inside the device’s own hardware instead of a removable card, which means that users are not “stuck” to an operator’s plans.
What are the advantages of eSIM?
As mentioned above, the idea of the chip within the hardware of your device itself will make the smartphones pass possibly to be thinner. In addition, users can change operators without restrictions, according to the one that best suits their needs.
As far as security is concerned, eSIM also has its advantages: As eSIM chips are not physical, they can not be stolen.
For those who like to travel, you do not need to purchase a new SIM while abroad, as eSIM offers a simpler and faster activation process and roaming charges would also be avoided.
For companies, the great advantage is that the same device can have more than two numbers, which avoids unnecessary expenses in the purchase of equipment.ESIMs also store private information that could be used to authenticate mobile networks.
With all these benefits and advantages, it may be only a matter of time before virtual chips become a reality on a large scale.
What devices can you use eSIM on?
Is this the other question you’re asking right now? We help.
The new iPhone XS, iPhone XS Max and iPhone XR models will support this feature, along with Apple Watch 3 and 4.
How to use eSIM?
As mentioned earlier, to take advantage of eSIM, you have to have the new devices with IOS 12 installed and the Apple Watch the WatchOS 05.
- Use one number for work calls and one for personal calls.
- Add a local data plan when you travel to another country or region.
- Have separate voice and data plans.
- A QR code or app from a mobile carrier operator with eSIM support.
- Both numbers can make and receive voice calls, as well as SMS and MMS.
- IPhone can only use one mobile data network at a time.
ATTENTION! To use two different carriers, the iPhone must be unlocked.Otherwise, both plans must be from the same operator. If the first SIM card is provided by a CDMA operator, the second SIM card will not support CDMA. Contact your service provider for more information.
If you have a business mobile data plan, check with your company administrator if this feature is supported.
Although it is still early to be certain of how this technology will affect us, it is unquestionable that very useful for many users, especially for those who use an iPhone to work.
Not having to walk with two phones is something that many Apple users crave, so the inclusion of this technology in the iPhone Xs, iPhone Xs Max and iPhone Xr will only bring benefits to users of Apple devices and it is very welcome!
