The departure toward mainstream adoption of eSIM technology has been massively reinforced with the arrival of the iPhone X S X S Max, and X R . We're now one step closer to deleting physical SIM cards. As you control this new technology, you may be surprised by the benefits it brings.
Unlike traditional SIM cards, which store your carrier data like your mobile number in a small, physically portable format, eSIMs are built into the phones themselves. If you're thinking about saving your primary phone line on your iPhone's eSIM as soon as the feature is available, there are some notable benefits, along with some downsides, before you take the plunge.
It's even easier to switch between carriers
One of the biggest benefits of saving your line in your iPhone's eSIM is the freedom it allows you to switch carriers. In fact, this technology will make switching from one company to another as easy as switching Wi-Fi networks and giving you more power over the network that depends on your business. That means if you ever decide to leave Verizon for T-Mobile (assuming your iPhone is paid), you no longer have to either go to a physical store to get a SIM or wait for it to be yours Front door is delivered, much less to pay for one. All you need now is a quick phone call, scanning a QR code, or simply installing a mobile operator's app to program your iPhone's eSIM for immediate activation.
To be fair, there is at least one small drawback for eSIM here: it is not yet supported by any carrier. It's only available on a handful of other phones like Google Pixel 2 and Nu X5. But now that Apple's latest flagships support this feature, you can expect the rest of the mobile industry to come through pretty quickly, so this will not be a problem for a long time.
. 2 eSIMs are Ideal for Travel
If you travel frequently, whether on business, privately or both, you know that the rest of the world relies almost entirely on the traditional SIM card to enable and store phone lines. In the past, travel abroad meant that your SIM card was removed and replaced with a phone line from a local mobile service provider such as Globe.
Program your primary lead into eSIM changes on your iPhone all this. It gives you the newly discovered ability to freely plug a foreign SIM card into your iPhone for local use while maintaining your original line to connect with loved ones and colleagues across the states. Of course, this only applies if your iPhone is unlocked. Therefore, contact your mobile service provider in advance.
. 3 You can enable multiple eSIM lines
Unlike traditional SIM cards, which can register and store only one phone line and can not be reused after disabling the line, eSIM allows you to have as many active phone numbers or data plans on your iPhone program, to Apple. Remember, you can only use one eSIM-based line at the same time as the active phone line stored on your iPhone's Nano SIM card.
We are currently not sure if the 2018 iPhones can support two eSIM -based numbers if the Nano SIM option is not used (no Nano SIM card inside the iPhone) for a total of two active lines. We contacted Apple for clarification and are still waiting for an answer. As soon as we receive more information, we will update this section. Stay tuned.
. 4 Phone thieves will have a harder time
The iPhone X S X S Max, and even the iPhone X R  are coveted devices, and as such will be primary targets for theft. In fact, iPhone theft is so common that we all know someone who was a victim, if not ourselves (I had one lost and one stolen). And while your line is stored via eSIM, it will not completely protect you from theft, which can make it much more difficult for criminals to resell your device for parts.
As a rule of thumb, thieves and unscrupulous sellers who trade are stolen The devices first remove the SIM card to prevent phone calls before they are briefly turned on for testing. When a phone line is stored in the eSIM of the iPhone, this becomes impossible and can prevent black market vendors from buying a stolen iPhone X S X S Max, or X R for fear of being caught.
Unfortunately, a line programmed on eSIM is not bulletproof, as criminals still have the ability to cleanly delete a stolen iPhone via either Restore or DFU mode. While the device will still remain iCloud locked after a clean restore (if enabled), we currently do not know if any phone lines stored on eSIM will remain intact.
We contacted Apple again. I got an answer. Of course, we will post an update as soon as we receive an answer, so check it out regularly.
