What exactly is eSIM?
The basic idea behind eSIM in iPhone is that the SIM card is integrated in the phone and thus takes up less space and is easier to relocate to another carrier. Another advantage is that you can store more than one eSIM on your iPhone. So if you have three separate numbers, you can actually create a triple SIM. However, the fact that there is no physical SIM card also means that you can not simply change SIM cards. For example, if your phone breaks down, there is a chance that device to replace it does not support eSIM.
The first thing you need to do is check if your mobile carrier provides eSIM services. Although the service is readily available to almost any major provider in United Kingdom and the US, it still does not have full coverage in other countries.
How to set up eSIM on iPhone?
This method only applies if you have an iPhone XS, iPhone XS Max, iPhone XR or later. If you use the eSIM setting on iPhone 12, you can also use it to browse 5G if available in your area. Note that the basic steps for setting up eSIM on iPhone are the same for all providers. You will need a secondary phone with a physical SIM card and a valid email address to complete the setup.
ESIM will be activated within 2 hours of completing the process. Also the services SMS will be blocked for 24 hours after you switch to eSIM.
- Send an SMS with the indication “eSIM <registered email ID>”To your mobile phone company's customer service number.
- You will then receive an SMS asking you to confirm if you want to continue.
- After consenting via SMS, you will receive a phone call for final confirmation.
- Once this is done, you will receive a QR code in your registered email.
- Go to IPhone Settings> Mobile data> Add data plann and scan the QR code you received. Once the plan is added, you can follow the instructions on your phone screen to highlight your SIM card and you are ready to go.
You will now see two mobile networks in the control center. You can choose which number to use for calls and SMS. There is also an option to enable mobile data switching, which allows your iPhone to use mobile data from both lines, depending on coverage and availability.
