eSIMs have been recently come into the limelight after first introduced in Apple’s IPad 9.7 and the Samsung galaxy gear S2 3G in 2016.

Following the eSIM movement, in 2017, 3 more devices that offer this feature launched. These included Google’s Pixel 2, Pixel 2 XL and Apple Watch Series 3. In September 2018, Apple launched 3 new iPhones (iPhone XS, iPhone XS Max, and iPhone XR) that all offer a dual sim with nano-SIM and an eSIM support.

With all these recent developments, it’s safe to assume that this is just the beginning and we can expect more devices that incorporate eSIM to emerge in the markets soon.

So how exactly can the eSIM be administered by users? For Apple users firstly, you will need to have an iPhone device that supports this feature (the new iPhones XS, XS Max or XR) and have the software version required or a later version of it.

Secondly, you will need a QR code or a carrier app from a wireless carrier that can support eSIM. In order for iPhone users to use two separate carriers, the device must be unlocked. If not, both plans have to come from the same carrier.

If a CDMA (Code-division Multiple Access) carriers provide your first SIM, then the second SIM will not support CDMA.

Setting up ESIM plan

One of the cellular plans use a nano-SIM and the other(s) will use eSIM. If you don’t have/don’t want to use a nano-SIM and your carrier supports it, an eSIM can be used as your sole cellular plan and all your information will be stored digitally in your device.

To activate the eSIM you have to scan the QR code provided to you by your carrier, use your carriers iPhone application or you can enter the information manually.

To manually enter the information, you have to:

  1. Settings> Cellular
  2. Click Add Cellular Plan
  3. Use the device to scan the QR code

If asked to enter a confirmation code, enter the number provided to you by your carrier.

Manually enter information

If you choose to set up your information manually you can do so by clicking enter details manually at the bottom of your iPhone screen.  Although you can store multiple eSIM profiles on your device, you can only use them one at a time.

You can change networks by clicking Settings> Cellular> Cellular Plans. Now you choose which network you want to use and then tap Turn On This Line.

Carrier app

If you use your carrier app, you need to firstly download the app if you don’t already have it and the simply purchase a cellular plan. 

As we know, the new 2018 iPhones have got the capacity to handle two cellular plans. One being nano-SIM and the other being an eSIM. So, which carriers can you subscribe to support your eSIM? The answer to this varies from country to country. Here is a list of mobile operators in countries that’ll offer/will soon offer eSIM:

Austria: T-Mobile

Croatia: Hrvatski Telekom
Czech Republic: T-Mobile
Germany: Telekom & Vodafone
Hungary: Magyar Telekom
India: Airtel & Reliance Jio
