What is eSIM and how to Activate it on iPhone With Your Carrier

eSIM (also known as Embedded SIM or digital SIM) is an alternative to the physical SIM cards we are used to in mobile devices. eSIM allows users to activate and manage mobile network connections directly on their phones, tablets, and other connected devices. Instead of storing a physical SIM card with your phone carrier’s information, you can register that same information directly on your device.

That means you won’t have to worry about which carrier has coverage in your area, or if you have a secondary plan with another company. You just need to make sure you have eSIM activated and once you purchase a subscription or initiate one with any provider, it will show up right on your device. That way, it is easier whenever traveling or switching between service providers.

Now, with the release of the iPhone 14, apple is offering only-eSIM models in the US for the series. This is a big move by Apple and a push for eSIM.

How to set up an eSIM on your iPhone

eSIM activation will take place during the initial setup process for your device. Once you have powered on your phone, you will be prompted to enter a few pieces of information. The information required to activate the eSIM may differ depending on your device.

Alternatively, to activate the new eSIM, you will also need to call your carrier to verify that you are able to use the cellular service.

  1. Ensure your wireless carrier supports eSIM. Most major US carriers support eSIM. You can check the full list here at apple.

  • Continue with the onscreen instructions.

  • If you are encountering problems with your mobile data plan or network, re-insert your sim card (if available)

iOS 12.1 will enable Dual SIM support with the eSIM

With iOS 12.1, Apple is introducing Dual SIM support for the iPhone XS Max and newer. This means that both of these devices can use an eSIM and a physical SIM card at the same time. In other words, you can use two different phone numbers on the same iPhone device. For example, you might want to keep your work number on your device and use the eSIM to connect to a local number while traveling overseas.

Perks of eSIM?

eSIM technology marks a significant change in the way we connect to cellular networks. This will allow you to seamlessly connect to an available cellular network and select the best roaming partner when outside the country. It will also let you connect to two separate networks at once.

This could be particularly helpful when traveling, as you can use a local network to avoid high roaming charges. With eSIM technology rolling out, you can expect a dramatic shift in how we connect to cellular networks.

What is the downside of eSIM?

eSIM might seem like the perfect solution, but many consumers are wary of the technology. There have been complaints about difficulty activating eSIM, and many new devices that support eSIM don’t provide the option for a physical SIM card either. If you prefer to use a physical SIM card instead of eSIM, you might be out of luck.
