Some of the useful things about the eSim on iPhone, android, and smart watches

The ‘e’ stands for embedded, and eSIMs are intended to replace traditional physical SIM cards. An eSIM is a tiny chip that is integrated into your handset as opposed to a removable plastic card inside your phone. It cannot be taken out and placed in another phone.

The data on an eSIM can be changed. It will probably be a while before eSIMs completely replace plastic SIMs. Currently, eSIMs are more frequently used as the second SIM card in dual-SIM phones.

The more well-known of the two solutions is this one. It’s a Subscriber Identity Module that fits into a drawer-like device and rests on a special tray. In order to identify and authenticate you on your carrier’s network, it is typically provided by a carrier and pre-programmed with account information like your phone number and security keys. Despite the fact that today’s smartphones are much more potent, SIM cards can also store contacts and SMS messages.

devices that support eSIM

While the Pixel 3 and newer Pixel devices support additional mobile carriers, Google’s Pixel 2 shipped with an eSIM that only supported Google Fi. The Samsung Galaxy S20 was the first Windows 10 device to ship with eSIM technology, and Microsoft’s Surface Pro LTE was the first device in the company’s lineup to do so.

With the Apple Watch Series 3, the first model to support LTE, Apple debuted eSIM in 2017. When the iPhone XS and iPhone XR were released the following year, Apple added eSIM to complement the physical SIM card slot and provide support for two phone lines, even though the Apple Watch uses eSIM exclusively. The physical SIM card slot was left in the 2018 iPad Pro, and Apple also added an eSIM as an alternative for users who preferred to use that.

In almost all iPhone models, Apple still uses a physical SIM card in addition to an eSIM. But the iPhone 13 was able to support two eSIM cards last year, allowing users to get dual-SIM support without a physical SIM card. This paved the way for Apple to eliminate the physical SIM card slot entirely from this year’s iPhone 14 lineup’s U.S. models, making eSIM the only method for activating your iPhone 14 on a carrier network.

The majority of other countries’ versions of the iPhone 14 still come with two eSIM cards and one physical SIM card slot, just like the iPhone 13. China stands out as the notable exception to this rule, where eSIM has never been a feature on an iPhone. Instead, Apple included two physical SIM card slots when it unveiled the iPhone XS/XR in China. Even with the iPhone 14 lineup, which in China still only has two physical SIM slots and no eSIM, that practice has persisted to this day.

Before heading up to Canada or down to Mexico to do some cross-border shopping, there is one thing you’ll want to keep in mind if you’re in the U.S. Only the American iPhone models support the mmWave 5G frequencies used for the fastest parts of Verizon’s 5G Ultra Wideband and AT&T’s 5G Plus coverage, even though.

How many esim can I install on iphone?

You can install multiple eSIMs on devices that support them, but the maximum number of active eSIMs varies depending on the device model. Multiple eSIMs can be installed simultaneously on Dual Active Dual SIM standby phones.

If you want to use one number for personal purposes and another for business purposes but don’t want to carry around two phones, this can be useful. You can choose which SIM to use to make calls, send texts, or use data while simultaneously receiving calls and texts on both numbers.

However, the maximum number of active eSIMs on your device varies depending on the device model. You can use Dual SIM with two active eSIMs or a nano-SIM and an eSIM on the iPhone 13 Pro Max, iPhone 13 Pro, iPhone 13, and iPhone 13 mini.

The Dual SIM feature on the iPhone 12 models, iPhone 11 models, iPhone XS, iPhone XS Max, and iPhone XR allows for the simultaneous use of one nano-SIM and one eSIM.

What benefits does an eSIM offer?

  • It is simpler to change networks.

It is much simpler to switch mobile networks with an eSIM. You can change to a different network with a phone call or online, eliminating the need to order a new SIM, wait for it to arrive, and then insert it into your phone. Additionally, you won’t need to look for a SIM “ejector tool” to get the old SIM out of your phone.

  • You can switch to a different network for a while.

Up to five virtual SIM cards can be stored on an eSIM at once. This implies that if you find yourself in a location without a signal on your preferred network, you can quickly switch between different networks.

Without having to physically insert a local SIM, it also makes it simpler to switch to a local network while traveling. While traveling, using a local mobile network can often be much less expensive than using your UK network and incurring roaming fees. Keeping your UK SIM will also make it less likely that you’ll lose your phone.

  • Takes up less room on the actual phone.

Another advantage of eSIMs is that physical SIM cards and their trays may one day become unnecessary. The makers of smartphones might use this area to increase the capacity of a phone’s battery or add new features to a device. With fewer holes, a handset will be better shielded from moisture and dust, which will result in fewer malfunctions.

Additionally, in some cases, a reduction in handset size is possible. However, because people don’t want to wear a big device on their wrist, wearables like smartwatches have a real space advantage. The Apple Watch Series 5 and Series 4 already have eSIMs, as do the Samsung Gear S2 and Gear S3 smartwatches.

What drawbacks does an eSIM have?

  • It’s harder to switch devices quickly.

Currently, you can easily remove the SIM from your phone and put it in another one to use in case it stops working while keeping your phone number and contact information (if your contacts are stored on the SIM) (if your contacts are stored on the SIM).

Although storing information and contacts in the cloud is intended to make it simple to transfer data, such as contacts, from one phone to another, doing so will be much trickier with an eSIM.

  • Nowhere to hide.

Additionally, eSIMs cannot be removed from a device, which may be considered a drawback if you worry about having your whereabouts tracked. However, this could also be a benefit since it makes it harder for phone thieves to conceal the whereabouts of a stolen phone.


a single eSIM cannot be installed on multiple devices. You can only install your eSIM once, and most eSIMs can only be installed on one device. As a result, you won’t be able to reinstall the eSIM if you remove it from your device.
