The eSIM adoption movement recently got a massive boost when the iPhone XS, XS Max, and XR revealed they offer the feature. As iPhone’s set technological trends, it’s only a matter of time before other companies and carriers start implementing eSIM into their businesses.

The idea of ditching physical SIM card is becoming more and more prominent. But what exactly makes the eSIM so different from the SIM card? If you’re on the fence about this new technology, you could be pleasantly surprised by what it has to offer.

Convenience

It’s clear that one of the most noteworthy differences between the eSIM is the freedom it allows to seamlessly switch carriers. The eSIM will make switching carriers as easy as changing Wi-Fi networks which will allow more power over the network which relies on your business to survive.

This means that you will be able to move from one company’s network to another without having to go to a physical store to receive a SIM or wait for one to be mailed to you. In addition to this, you could say you don’t pay for this service anymore as you would be getting one pre-installed in your phone.

Now all you have to do is scan your QR code or manually install the carrier’s app to program your device’s eSIM for instant activation.

Travel-friendly

The eSIM is going to be life-changing for frequent travelers. Whether it’s a business or leisure trip, traditionally travelers had to purchase a physical SIM which meant removing their local SIM and replacing it with the new line sourced from a local carrier in the country their visiting. Not only is this a tedious process, but you also risk potentially losing your home SIM.

The eSIM would eliminate this hassle as all you would have to do is program your home line into your phones eSIM. For devices that offer eSIM and a physical SIM tray, this would give users the ability to freely insert a foreign SIM into your device for local use while retaining your original line, allowing you to stay connected to your family and friends back home. However, this is only applicable if your device is unlocked, so always check with your carrier beforehand.

Option to Join Multiple Networks

Another option is to switch networks using your eSIM as the eSIM allows you to have multiple profiles, you can join multiple carriers and switch between them. So when you are in your home country, you will use your primary carrier profile then change to the other countries local carrier (given they offer an eSIM plan) and switch to their network.

Unlike physical SIMs that can register and store only one line and cannot be reused once the line is deactivated, the eSIM will allow you to program as many networks and data plans to your device.

pickpockets & burglars Will Face Difficulties

It is a known fact that Apple offers high priced sought-after devices, making them a target for theft. With that being said, the new iPhone XS, XS Max, and XR will surely be targeted as well. iPhones are commonly stolen to be resold on the black market. While the eSIM wouldn’t completely shield you from having your iPhone stolen, it would make it much harder for thieves to resell your device.

Thieves and reprobate vendors that sell stolen devices have to first remove the SIM card to prevent phone calls before switching it on for testing. With a device that using an eSIM, this will make it impossible for the thieves to do this, demotivating buyers from purchasing the stolen device in fear of being caught.

Sadly, the thieves could still reset the stolen device via either Restore or DFU mode to wipe out the contents of the device. However, if an iPhone’s ICloud was enabled, the device will remain locked.
