What is eSIM, how it works and everything else you need to know


Apple has finally adopted the idea of Dual Sim support for its fans in all the markets. It is important to note that China, Hong Kong, and Macau will be the only markets that will get support for two physical SIM slots (dual sim iPhone), However, Apple will offer a secondary eSIM option to the rest of the world, including India.

This means that the second SIM slot will be carrier locked, and users will not be required to put in a physical SIM card to activate connection. To let you know how does this gonna work, Here, we have explained you about the eSIM and how you can configure your mobile connection on it.

Everything you should know about eSIMS

Before we move to what eSIM is, let’s take a moment to explain you what is primary and secondary sim in iPhone especially.

Your primary SIM

The new iPhones will continue to have a traditional nano-SIM slot where you can insert your existing SIM card from your mobile network operator. Once you insert your sim, the phone will connect to your network and set-up the configuration on the phone, which will enable calls, SMS and data connectivity immediately.

What about the second SIM?

Now, in case you have a second mobile connection that you use right now, you’ll also have a SIM card. But for it – here’s where it gets tricky.  The Apple iPhone XS, XS Max and XR have an eSIM built into the phone already, rather than a slot for you to insert your second SIM card.

Now, What is eSIM?


eSIM of a carrier is digitally stored in one’s device. So, users do not need to put in a physical SIM card to access cellular network. Also, cellular plans can be remotely activated on eSIM. Apple iPhone XS, iPhone XS Max users will store and can switch between two eSIM connections in their phone, but can use only one at a time as Apple is using a fail standby option.

It is important to note that both the numbers can be used to make and receive calls as well as send and receive SMS and MMS. Of course, the phone can use only one cellular data plan at a time.

Apple iPhone XS, iPhone XS Max with dual-SIM support: What this means for India users

In India, carrier options that offer eSIM connection are limited. Right now, only Airtel and Reliance Jio connection can only be used to activate eSIM, However, more telecom operator like Vodafone are expected to offer this feature soon.

How to activate eSIM

In order to use two different carriers on iPhone XS, iPhone XS Max; users need to make sure that their phone must be unlocked. Or else, both the plans must be from the same carrier. People will need to use their iPhone to scan the QR code that their carrier provided or enter the confirmation code given by the carrier to activate or set up a cellular plan with eSIM. Go to Settings and then click on Cellular. Next, tap Add Cellular Plan.

How to switch between SIM cards

After both the SIM slots are activated, users can set their default number to call or send a message to someone who is not in their Contacts app. This number will also be used by iMessage and FaceTime. In fact, users also have the option to choose a default number exclusively for cellular data.

Apple iPhone XS, iPhone XS max users can either choose their primary number as default for voice, SMS, data, iMessage, and FaceTime. In this case, the secondary will only be available for voice and SMS. In case, users should choose their secondary number as default, the primary will then be restricted for voice and SMS. There is a third option as well to use the second option for cellular data only.

How to make calls, etc

When both the SIM slots are activated on Apple iPhone XS, iPhone XS Max, the phone will by default choose the same number that the person used to call contact the last time. It chooses the default number to make a call in case the user has not called the contact ever before. There is an option to specify the number to call contact as well.

Either of the two numbers can be used to make or receive calls. As per an official Apple support page, users will not get a missed-call notification if they are on a call and they get an incoming call from the second number at the same time. Instead, the incoming call will go to their voicemail if they have set up one with their carrier; or users can set up call forwarding on their other number to avoid missing important calls.

Pros and Cons of eSIM

Now, you might be wondering what is the of an eSIM slot when there is a traditional method of physical SIMs is so popular. Every coin has two sides, similarly, while there are cons to this, there are some pros as well.

Let’s see the Good Side of having an eSIM

Most importantly, eSIM cards built into the phone are not just limited to a single mobile connection. However, you can configure multiple networks to work on the same eSIM and device. Isn’t that great?

This simply means Apple iPhones are now capable of having more than two connections configured on the device. But with a limitation, that only two of these can be active at any given time, but switching between multiple connections will be possible.

The second most important benefits of having eSIM is, it’s indestructible nature. While traditional SIM cards can be easily damaged or lost, the eSIM is as safe as the phone is.

However, where there are pros, there are cons. Let’s see the other side too:

Where traditional SIM cards are easy to swap and configure whenever you like, eSIM activation will need you to go to your mobile operator for the QR and confirmation codes. Therefore, you won’t simply be able to switch phones whenever you like, and will need to make a trip to your nearest Airtel or Jio store if you want to activate the connection. Additionally, eSIM connectivity is only limited to two operators in India for now, so it won’t work if your second connection is on a network other than Airtel and Jio.
