What is eSIM?

You're hearing about eSIM more and more and wondering what it actually is? You've come to the right place. We'll explain it simply, without technical jargon.

The Simple Explanation

An eSIM is a SIM card that's already built into your phone. Instead of swapping tiny plastic chips when changing carriers or traveling, you simply download a new plan – similar to installing an app.

The "e" stands for "embedded" because the SIM chip is soldered directly inside the device. The magic is that it can be reprogrammed remotely, allowing you to add new plans whenever you need.

eSIM vs. Physical SIM: What's Different?

Why Travelers Love eSIM

This is where eSIM truly shines. Before eSIM, getting mobile connectivity abroad meant:

• Hunting for SIM card vendors at airports (usually overpriced)
• Dealing with language barriers and confusing plans
• Keeping track of your original SIM (and that tiny ejector tool)
• Or just accepting ridiculous roaming charges

With a Simcardo eSIM, you purchase a travel data plan online, scan a QR code, and you're connected. No physical cards, no waiting, no hassle. You can even set it up before your flight and land already connected.

How Many eSIMs Can You Have?

Most phones can store 8-10 eSIM profiles at once. Think of it like apps – you can have many installed, but only a few active.

In practice, most users keep two profiles active:

• Your regular home plan (for calls and SMS)
• A travel eSIM (for affordable data abroad)

This dual-SIM setup is perfect for travelers. Your friends can still reach you on your normal number while you surf on affordable local data.

Is eSIM Secure?

Absolutely. In some ways, eSIM is even more secure than physical SIM:

• Can't be stolen – Thieves can't simply remove your SIM and use your number
• Encrypted downloads – Your eSIM profile is delivered securely
• Remote management – If you lose your phone, the eSIM can be remotely deactivated
