If you've been wondering what eSim stands for, you've come to the right place. This software solution replaces the physical SIM with a smaller chip. Because this chip is rewritable, it's much easier to switch networks without removing the original. However, eSIMs are most commonly used as the second SIM in dual-SIM handsets. If you're in the UK and want to keep your existing carrier, you should opt for eSim.
The eSim technology is a form of dual-SIM card. It consists of two components: hardware and a pre-loaded profile. It can be used for consumer electronics and other devices that do not require mobile service. Consumer-grade eSIMs are used for smartphones and tablets. They are ideal for small-attached devices, such as wearables and fitness trackers. In addition to these applications, eSIMs are suitable for use in IoT deployments of all types.
eSim is an advanced technology for mobile devices. It replaces the traditional SIM card and allows users to use two different carriers simultaneously. Its new features make eSim compatible with a variety of devices. eSim cards enable wireless software beaming. Users can use one number on their physical SIM card and another on their embedded SIM. This technology also allows them to keep their existing number when changing handsets, and they do not need to get new SIM cards to keep using the same carrier.

eSim is a small chip embedded inside a mobile device. It works similarly to the Near-Field Communication Chip used in payment technology. Unlike a physical SIM card, eSIMs can be rewritable, allowing the user to switch operators without physically swapping SIMs. Furthermore, eSIMs have a secure element known as eUICC that allows for multiple profiles. eSIMs are programmed through over-the-air management, allowing the users to download new profiles without having to physically swap SIMs.
Activating an eSim is simple. Users can sign up through the app or website of the provider of their choice. Once the registration is completed, the eSim becomes active and works immediately. If they need to change their phone number, they can deactivate the home profile to avoid any confusion. Activating an eSim requires just a few minutes to complete. For some users, activating it may be as easy as scanning a QR code or keying in a security PIN.
eSim (electronic SIM) is available in the UK on some mobile networks, but not all. It is typically only available on Pay Monthly plans, not Pay As You Go. Using an eSim can cause complications when switching phones, as eSim cannot be used in the same way as a physical SIM card. You will need to convert your eSim to a physical one if you want to use it with a different network.
eSim is supported by three of the UK's major mobile networks. Three has stated that it will start supporting eSIMs by 2022. Virgin Mobile and BT Business customers can use it too. EE is one of the few networks to offer this option. The following networks do not offer eSim. However, Virgin Mobile and O2 do. If you're interested in trying out eSim on your smartphone, visit your local shop and ask for an eSim-enabled device.
eSim connectivity is available on most smartphones in the UK. Dual-SIM connectivity means that you can use the same mobile network on two different devices. EE plans support dual-SIM capability, but only for new Pay Monthly lines. You cannot use an eSim on your existing number. The new EE devices have a special chip for eSim support. You can also use a SIM card from another network to use eSim on the same phone.
You can choose between Pay Monthly plans with compatible eSim devices from EE, O2, and Vodafone. Other networks are working on eSim support. The latest iPhones and Samsung Gear S2 and S3 support eSIMs. If you're not using an eSim-enabled phone, you should consider eSim-enabled smartwatches to be compatible with other network SIMs.
In a perfect world, an iPhone with dual SIM capability would also work outside China, but that's not going to happen. Apple has taken great pains to squeeze as much space inside its devices as possible, combining chips and even removing the headphone jack. However, eSim isn't yet widely adopted in China. It's unclear whether Apple will add support for eSim on its iPhone XS Max smartphones.
Apple has long been giving special treatment to the Chinese market. Not only does the company sell a special version of the iPhone in the country that's not sold elsewhere, it's also supporting eSim on the new Apple Watch. The eSim technology isn't widely adopted yet - only seven major Chinese cities support eSim, and China Mobile only introduced eSim services in June.
GigSky is an eSim that works on non-Chinese dual-SIM iPhones in China. You can connect the two SIM cards using a QR code. The app requires the user to grant permission for the GigSky eSim to access location services and send notifications. eSim supports dual-SIM technology in China, Hong Kong, and Macau. If you need dual-SIM support on your iPhone, you can use GigSky's eSim.
Apple's new iPhones will have dual SIM capabilities, but the eSim technology won't be available in the rest of the world until later this fall. In the meantime, the iPhone will have two plastic SIM card slots. This means that the iPhone won't be able to work outside China immediately. Instead, the dual-SIM feature will be enabled later this fall with a eSim software update.
