Step-by-Step: How to Switch to eSIM

Switching to eSIM has become one of the simplest ways to stay connected, whether you're traveling abroad, changing carriers, or upgrading your smartphone. But despite how easy the process seems, many users still feel confused the first time they try switching to eSIM.

I remember the first time I switched from a physical SIM — it felt strange removing the card I had used for years. But after activating my first eSIM, everything became faster, cleaner, and honestly… much more convenient.

In this complete guide, you’ll learn how to switch to eSIM step-by-step, what to prepare, how long the process takes, what can go wrong, and how to avoid common mistakes.

What Is an eSIM and Why Switch?

An eSIM (embedded SIM) is a digital SIM already built into your smartphone, tablet, or laptop. Unlike a traditional SIM card, you don't need to insert or remove anything — you simply activate it through a QR code, app, or manual entry.

Why switching to eSIM is worth it:

• No need to buy physical SIM cards

• Fast online activation (1–2 minutes)

• Easily switch carriers anytime

• Perfect for travel

• Use multiple profiles on one device

• No risk of losing or damaging a SIM

For travelers and remote workers, eSIM has become a game-changer — especially when buying data plans abroad.

Before You Switch: What You Need to Check

Switching to eSIM is easy — but you need to prepare a few things to avoid problems.

1. Check if your phone supports eSIM

Most modern devices support eSIM, including:

• iPhone XS and newer

• Samsung Galaxy S20 and newer

• Google Pixel 4 and newer

• Many Xiaomi, Motorola, Huawei, Oppo, Sony devices

If you're not sure, go to:

Settings → About → IMEI → Look for “IMEI (eSIM)”

If you see it, your phone supports eSIM.

2. Make sure your phone is unlocked

If your device is locked to a specific carrier, some eSIMs may not activate.

To check:

iPhone:Settings → General → About → "Network Provider Lock" must say No SIM restrictions

Android:Settings → Connections → Networks → Check carrier status(or contact your operator)

3. Back up your device

This isn’t required, but always a good idea — especially when changing SIM settings.

4. Decide if you're switching your main number or adding a travel eSIM

Most users want one of these:

• Switch physical SIM → eSIM (same number)

• Switch carrier and activate new eSIM

• Add a second eSIM for travel (my personal favorite)

Know what you want before you begin.

How to Switch to eSIM — Step-by-Step Guide

Here is the easiest and most universal method that works for most carriers worldwide.

Step 1: Request eSIM activation from your carrier

You have 3 options depending on your provider:

1) QR Code

Your carrier sends a QR code by email, SMS, or in the app.

2) Activation Code (SM-DP + code)

Some carriers provide manual activation details.

3) Activation through their official app

This is the most common for travel eSIMs, like Airalo, Nomad, Global YO, etc.

If you’re switching your main number, your carrier will generate an eSIM for your existing phone number.

Step 2: Remove or deactivate your physical SIM (optional)

If you're transferring your main number, your physical SIM may stop working automatically once the eSIM activates.

But I personally prefer removing the physical SIM after the eSIM is confirmed active — just in case something goes wrong.

Step 3: Activate the eSIM on your phone

On iPhone

1. Settings → Cellular

2. Add eSIM

3. Scan QR code or choose "Use QR Code"

4. Follow on-screen instructions

5. Wait 10–30 seconds

6. Your eSIM should show as “Active”

On Samsung Galaxy

1. Settings → Connections

2. SIM Manager

3. Add eSIM

4. Scan QR or enter manual code

On Google Pixel

1. Settings → Network & Internet

2. SIMs

3. Add eSIM

Step 4: Set which SIM handles calls, data, and SMS

If you now have multiple SIM profiles:

• Choose your default number (calls/messages)

• Choose your data SIM (usually the eSIM)

• Turn on data roaming if it’s a travel eSIM

• Turn off the SIM you don’t need

This step is especially important while traveling.

Step 5: Test the connection

Once activated:

• Open browser

• Run a speed test

• Try sending a message

• Make a test call (if your plan includes calls)

If everything works — you’re done!

My Personal Experience Switching to eSIM

I’ve been using eSIMs for a long time now, especially for international travel. The first switch from my physical SIM took about 3 minutes — and honestly, it was much easier than I expected.

What surprised me most was how convenient it felt afterward. No more tiny SIM trays, no searching for paper clips, no visiting stores abroad. Everything is digital, fast, and clean.

Most importantly, when traveling, I can activate a new data plan before my plane even lands. This is why I always prefer eSIM now.

Common Problems and How to Fix Them

Even though switching to eSIM is simple, sometimes problems appear. The good news? They’re easy to fix.

Problem 1: eSIM Not Activating

Solution:

• restart your phone

• turn airplane mode ON → OFF

• check if the phone is unlocked

• activate via Wi-Fi (not cellular)

• enter manual SM-DP details if QR fails

Problem 2: No Internet After Activation

Solution:

• turn on Data Roaming

• select correct SIM for mobile data

• reset network settings

• check APN settings (your carrier will provide them)

Problem 3: Physical SIM still active

You can disable it manually:

Settings → Cellular → Turn off line

Problem 4: Can’t scan QR code

Use the manual code. Every QR contains the same data, just in text form.
