eSIM on iPhone: Understanding its Functionality and Set-up Guide
Apple has been at the forefront of embracing eSIM technology in its cellular devices since 2018. The iPhone, in particular, has become a go-to device for travelers because of the need to switch cellular data plans frequently—a capability that eSIM technology conveniently provides.
The rise of Digital SIM as the primary cellular service technology is evident in devices like the iPhone 14, which exclusively supports eSIM. Consequently, numerous telecommunication companies have started incorporating virtual SIMs into their service offerings, leading to an increase in international eSIM providers.
This article will serve as a guide to understanding what an eSIM is, how it works on iPhones, which iPhone models support eSIM, and the process of setting up an eSIM.
Understanding eSIM
An eSIM is a digital SIM that enables the activation of a cellular data plan from either a local or international operator without the requirement of a traditional SIM card.
eSIM technology operates on a minute chip embedded in your Apple device and is activated when a virtual SIM plan is downloaded and added. The versatility of eSIMs has made them incredibly popular, as they can be used across various devices, including laptops, smartwatches, and even cars.
How Does an eSIM Work on an iPhone?
eSIM functionality on iPhone devices mirrors its operation on other eSIM-supporting devices. Each iPhone contains an embedded chip where a Digital SIM card can be downloaded and installed once purchased from a local or international eSIM provider. The following section details the process of installing and activating your eSIM on an iPhone that supports virtual SIMs.

Capacity for eSIMs on an iPhone
Most iPhone models that support virtual SIM cards can house up to 20 eSIMs. However, only one eSIM or two Digital SIMs can be used simultaneously. Depending on your iPhone model, you may also use a traditional SIM card and a virtual SIM simultaneously. This functionality is referred to as Dual SIM.
Understanding Dual SIM Card
Dual SIM allows you to utilize a nano-SIM (the classic) and an eSIM (virtual card) concurrently. This means you can use data, receive and make calls with both SIMs. Many iPhones offer this functionality, but with the introduction of iPhone 14, which lacks a physical SIM slot, two eSIMs can now be used simultaneously.
