Does iPhone 12 Have eSIM? Complete Guide for 2025

Does iPhone 12 Have eSIM?

If you’re considering getting an iPhone 12 or already own one, you might be wondering — does iPhone 12 have eSIM support? The short answer is Yes. All models in the iPhone 12 lineup — iPhone 12, iPhone 12 Mini, iPhone 12 Pro, and iPhone 12 Pro Max — come with dual SIM capability, which includes one physical nano-SIM slot and one digital eSIM.

In this article, we’ll explore what eSIM is, how it works on the iPhone 12, its benefits, and how to set it up.

What is eSIM?

An eSIM (Embedded SIM) is a digital SIM card built directly into your device. Unlike traditional SIM cards, eSIM doesn’t require a physical card — instead, it allows you to activate a cellular plan from your carrier digitally.

Apple first introduced eSIM support in the iPhone XS, XS Max, and XR in 2018, and the iPhone 12 series continues this feature.

One number for personal use and another for business.
One local SIM for your country and another eSIM for international travel.

Does iPhone 12 Have Dual eSIM?

While iPhone 12 supports one eSIM and one physical SIM, it does not support two eSIMs simultaneously. If you want two eSIM lines at the same time, you’ll need newer iPhone models like the iPhone 13 or later, which offer dual eSIM support.

Things to Know Before Using eSIM on iPhone 12

Carrier Support is Key – Not all mobile networks support eSIM, especially in developing markets.
Activation is Permanent – Once activated, you can’t transfer the eSIM to another phone unless your carrier allows it.
