How to Activate eSIM: Complete Guide
eSIM is a virtual SIM card that is stored in your smartphone's memory and allows you to connect to a cellular network without a physical carrier. eSIM activation may seem like a complex procedure, but it's actually a simple process that will take only a few minutes. In this guide, we'll walk through all the stages of activation, device compatibility, typical problems, and their solutions. Whether you're switching to eSIM for the first time or relocating abroad and need a local number, this instruction will help you quickly set up your connection without unnecessary complications.
What is eSIM and Why You Need It
eSIM (embedded SIM) is an integrated microchip built into modern smartphones and tablets. Unlike a traditional plastic SIM card, eSIM exists only as a digital code and takes up minimal space inside the device.
Main advantages of eSIM:
- Convenient activation. You don't need to visit an operator's office or wait for card delivery. Everything is done online in a couple of clicks.
- Flexible tariffs. You can quickly switch between different operators and tariff plans.
- Multiple number support. You can store several eSIMs on one device simultaneously and switch between them.
- No card loss. A virtual SIM cannot be lost or physically broken.
- Savings when traveling. Especially relevant for tourists who frequently visit different countries.
Today eSIM is supported by flagship iPhone models (X and newer), Samsung Galaxy, Google Pixel, Huawei, and other modern smartphones.
Checking Device Compatibility
Before activation, make sure your device supports eSIM.
For iPhone: - Open «Settings» → «Cellular» - If you see the option «Add eSIM» or «Mobile Plan», your device supports eSIM - iPhone X and all newer models have this support
For Android devices: - Go to «Settings» → «Network and Internet» → «Mobile Network» - Look for an option about eSIM or mobile plans - Support is available on Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most flagship models from other manufacturers
Online verification: Visit the official website of your device manufacturer and search for your model. The support page will contain information about eSIM availability.
Also make sure mobile data is enabled and your operator supports eSIM in your country.
eSIM Activation Process Step by Step
Preparing Documents and Information
Before you start the activation, prepare:
- Passport or other identity document (not required by all operators, but good to have)
- Email address to receive confirmations
- Phone number (sometimes required for verification)

Installation via QR Code
This is the fastest method:
-
On iPhone: - Go to «Settings» → «Cellular» - Tap «Add eSIM» - Select «Scan QR Code» - Point your camera at the QR code from the email - The system will automatically download and install the profile - Follow the prompts to complete
-
On Android: - Open «Settings» → «Network and Internet» → «Mobile Network» - Tap «Add eSIM» (the name may vary) - Select the QR code scanning option - Point your camera at the code - Wait for the profile to download
Manual Installation Without QR Code
If the QR code is not available:
- Get the activation code (usually 20-30 characters)
- On iPhone: «Settings» → «Cellular» → «Add eSIM» → «Enter Details Manually»
- On Android: «Settings» → «Network and Internet» → «Mobile Network» → «Add eSIM» → «Enter Code»
- Enter the received code
- Wait for synchronization
Activation After Installation
After the profile has downloaded, you need to activate it:
- Make sure your device has an internet connection (via WiFi or current SIM)
- Go to eSIM settings
- Select the «Activate» option
- Confirm the action
- Wait for the process to complete (may take 5-15 minutes)
After activation, you will see the signal of the new operator's network in your phone's status bar.
Typical Problems and Solutions
Problem: QR code is not scanning
Solution: Make sure the camera has access in the settings. Try printing the code on paper with better contrast or open it on another device and scan it from the screen.
Problem: Error when entering code manually
Solution: Check that the entered characters are correct (take into account uppercase and lowercase letters). Make sure the code has not expired (codes usually last 30-60 days).
Problem: Profile is installing but not activating
Solution: Check your internet connection. Restart your device. Try to activate through the operator's app (if available).
Problem: No network signal after activation
Solution: Make sure eSIM is set as the primary number for mobile data. Check if the operator has coverage in your location. Restart in airplane mode and back. Contact your operator's support.
Problem: Need eSIM for a second number, but the slot is occupied
Solution: If your device supports two eSIMs, simply add a new profile in the settings. If there are no more slots, delete the old eSIM before adding a new one (if it's not required for work).
Helpful Tips for Users
-
Save codes and QR codes. Take screenshots of the QR code and save activation codes before activation. They will be useful when switching to a new device or restoring access.
-
Learn backup options. Many manufacturers allow you to save an eSIM profile to the cloud. Use this feature as backup.

Check roaming conditions. If you plan to use eSIM abroad, make sure the operator covers the countries you need.

Test before traveling. If you activate a new eSIM for travel, test it at home, make sure the signal is normal and the internet is fast.

Have a backup communication method. Keep a physical SIM card from your main operator in case of eSIM problems.
