The SIM card is an important part of your phone. It allows you to use different cellular networks, and stores your contacts and phone numbers.
Until eSIM technology is fully adopted, you’ll still see a tray for physical SIMs on some devices. Fortunately, manufacturers are moving toward replacing these with eSIMs.
They’re more secure
eSims have been dubbed the “must have” of the mobile device world and are expected to make their way into more phones than ever. They’re less likely to be stolen and can be programmed to request verification from operators whenever someone tries to change their profile, according to industry experts.
They also use technology to help secure data and improve battery life. One example is the Subscription Management Data Protection (SM-DP+) feature.
It’s no secret that a hacker can download a malware-infected SIM card into your device, but this isn’t as simple with an eSIM as it is with a traditional sim.
Aside from security, eSIMs are also less prone to manufacturing errors. This makes them the best choice for the IoT and other connected devices that will require constant updates to stay compatible. They also improve energy efficiency by eliminating the need for removable batteries. And they make it easier to switch carriers, which is a plus for consumers.
They’re more convenient
If you’re the kind of traveler who likes to take advantage of a good global data plan, you know how frustrating it can be to pay roaming fees until you actually get there. Especially if you’re not traveling with a dual-SIM phone, having to change your SIM cards every time you move can leave you disconnected and missing out on a lot of important communication.
Thankfully, there’s an alternative to these frustrating experiences: eSims.
These are small, software-based SIMs that replace the physical SIM card and its tray in modern devices. They can fit in wearables such as watches and even smartphones, allowing manufacturers to add more features or improve battery life without taking up more room in the device.
They’re also easier to use than a traditional SIM card, as you can switch networks with a phone call or online. Plus, you won’t need to search for a specialized SIM ejector tool to remove a damaged card from your phone.
Are Esims Better?
They may not be the latest and greatest, but eSims are still pretty cool. They are smaller than physical SIM cards, and they can be a lot cheaper to make, thanks to less components, a simplified design and less power consumption.
It’s also easier to switch between multiple profiles on an eSIM, which is especially helpful for travelers who often change their location. It’s one of the many reasons that eSIMs are quickly becoming the preferred choice for a lot of people.
They also help businesses get a grip on wireless connectivity, particularly those with large scale machine-to-machine deployments that need to support mobile service for thousands of devices. Using eSIMs, account managers or IT personnel can remotely adjust cellular plans on thousands of devices, from robots to drones.
They’re more versatile
If you’re constantly traveling around the world, you may find that using a mobile device without a SIM card can be tricky. This can cause problems during those vital first hours after arriving in a new country, as you’ll often be disconnected until you get your phone connected to the local network.
Thankfully, there’s a solution to this problem — an eSIM.
With eSims, users can store multiple profiles on their devices, making it easy to switch between different networks and plans at will. This feature is especially handy for business travelers or expats who travel regularly.
Additionally, it saves on physical space in phones and wearables – which can allow manufacturers to increase battery size or add new features. This is great news for smartphone makers who are looking to shrink their devices, or for fitness trackers and other wearables that need standalone 4G connectivity.
