Before setting up your eSIM, make sure you have purchased the right plan from a trusted provider. You can explore Way2go eSIM Products to choose a suitable data package for your destination. To ensure a smooth activation process and avoid errors, you only need to carefully check the following 3 factors:

Your phone supports eSIM and is unlocked: First, make sure your phone supports eSIM, usually iPhone XS models or later, or Samsung S20 models or later. Most importantly, your device must be an unlocked international version, not a carrier-locked phone, so that it allows you to add a new mobile carrier.
A stable Wi-Fi connection is required: Since an eSIM is digital, you need a continuous internet connection to “download” it to your phone. Connect to a strong Wi-Fi network, whether at home, the airport, or your hotel. Avoid using a weak 3G or 4G connection during installation, as this can easily cause the profile download to fail halfway.
Prepare the QR code or manual activation code: When you purchase an eSIM, the provider will send you a QR code by email or on a physical card. Have this code ready before starting. If you do not have another device to display and scan the QR code, prepare the manual activation details instead.

The installation steps below apply to most Apple devices that support eSIM, from the iPhone 11 generation to the iPhone 17 Pro Max. Depending on your situation, you can choose one of the two methods below.

2.1. Method 1: Use A QR Code Recommended

This is the fastest and easiest method, with the lowest risk of typing errors. To set it up, follow these steps:

Step 1: Open network settings. Go to the Settings app on your iPhone, then select Cellular or Mobile Service.
Step 2: Start adding the eSIM. On the connection management screen, scroll down and tap Add eSIM.
Step 3: Choose the scanning method. The Set Up Cellular screen will appear. Here, select Use QR Code.
Step 4: Scan the code. Point your iPhone camera at the QR code provided by your service provider. Your phone will automatically recognize the profile. You only need to tap Continue and wait for the system to finish the installation.

2.2. Method 2: Manual Setup When You Cannot Scan The QR Code

This method is a useful backup option if your phone camera is not working, or if the QR code image is opened on the same iPhone you want to install the eSIM on, meaning you do not have another screen to scan from.

Step 1: Follow the same opening steps as above: go to Settings > Cellular > Add eSIM > select Use QR Code.
Step 2: When the camera scanning screen appears, do not scan the code. Instead, look at the bottom of the screen and tap Enter Details Manually.
Step 3: The system will ask you to enter the required information. Open the email from your provider, then copy and paste the following two details accurately:
- SM-DP+ Address
- Activation Code
Step 4: Tap Next in the upper-right corner of the screen. Wait a few seconds for the system to verify the network, and your eSIM will be ready to use. It is best to name this new eSIM, such as Travel or Work, so you can manage it more easily later.

The Android ecosystem is more diverse than iOS, as each phone brand may slightly customize the names used in its settings interface. However, the general process is still very simple and easy to follow. Below is a detailed guide for the most popular Android models today.

3.1. Steps To Activate eSIM On Samsung Phones Galaxy S, Z Fold And Z Flip

Samsung is one of the brands that supported eSIM early and offers one of the most stable eSIM experiences. To set up a new mobile network profile on Samsung flagship models, follow these steps:

Step 1: Open the connection manager. Go to Settings > Connections > SIM Manager.
Step 2: Start adding a new network. On this screen, find and select Add eSIM.
Step 3: Scan the QR code. Next, choose Scan QR code from service provider and point your camera at the QR code you have prepared so the phone can recognize it automatically.
Step 4: Enter the code manually if needed, then complete the setup. If the camera cannot recognize the QR code, tap Enter activation code. Copy and paste the character string sent by your carrier. On Android, this code often starts with LPA:1$... Then, tap Download so your device can save the mobile network profile.

3.2. Steps To Activate eSIM On Other Android Phones: Google Pixel, Oppo, Xiaomi And More

For devices running stock Android, such as Google Pixel, or phones from brands like Oppo and Xiaomi, the installation steps are usually found in the mobile network settings:

Step 1: Access network settings. Go to Settings > Network & internet or Mobile networks, depending on the wording used by your phone model.
Step 2: Add a new SIM. Find the SIM management section, then tap the plus icon (+) or select Add a network / Add eSIM.
Step 3: Confirm the eSIM download. The system may ask which type of SIM you want to install. Choose Download a SIM instead? or confirm that you want to download a wireless network profile, then tap Continue.
Step 4: Scan the code and connect. The camera interface will appear so you can scan the QR code. Similar to Samsung, if you want to set it up manually, look for Need help? or Enter it manually at the bottom of the screen to enter the activation code. Finally, tap Download or Turn on to complete the installation process.

4. Important Notes And Post-Activation Settings

After successfully downloading the network profile to your device, keep the following 3 rules in mind to optimize your experience and avoid unnecessary issues during your trip:

4.1. Label Your eSIM For Easier Management

Right after installation, the system will allow you to name the new mobile network. Instead of keeping confusing default names such as Secondary, Personal, or Business, rename it clearly as “Travel,” “Data,” or the country you are visiting, such as eSIM Thailand. Clear labeling helps you avoid accidentally selecting your physical SIM from home when using the Internet, preventing unwanted roaming charges.

4.2. Check Data Roaming Again

Whether you are using an iPhone or any Android device, this is the essential key that allows a travel eSIM to connect to the local network. If you have not enabled it during the previous setup steps, go to your mobile network settings and make sure the Data Roaming toggle is turned on.

4.3. Never Delete Your eSIM When An Issue Occurs

This is the most common mistake users make. Most QR codes today can only be scanned and installed once for security reasons. If the signal is unstable or the network drops, try turning Airplane Mode on and off, or restart your device. If you tap “Remove Data Plan” or delete the eSIM, the profile may be permanently lost, and you may not be able to use the old QR code to reinstall it.

5. Frequently Asked Questions About How To Activate eSIM

Frequently Asked Questions About How To Activate eSIM

5.1. How Long Does It Take To Activate An eSIM?

Downloading an eSIM profile to your phone is very quick and usually takes only about 1 to 2 minutes over Wi-Fi. However, the time it takes for your device to detect and successfully connect to the local carrier’s network after you arrive may range from 5 to 15 minutes. If you still do not have a connection after waiting for a while, simply restart your phone or turn Airplane Mode on and off to prompt the device to search for the network again.

5.2. What Should I Do If I Accidentally Delete My eSIM In Settings?

You cannot restore it yourself by scanning the old QR code again, as each code is usually valid for one installation only for security reasons. At this point, stay calm and contact the customer support team of the eSIM provider immediately. Provide your order number or purchase confirmation email so they can check your request and issue a new activation code if eligible.

5.3. Can I Set Up And Use An eSIM Without Wi-Fi?

You need to clearly distinguish the connection requirements between the setup stage and actual usage.

For the setup process: You must have an Internet connection, either stable Wi-Fi or a hotspot shared from another device. Your phone needs a network connection to download the digital profile from the carrier’s server to the system.
For the usage process: Once the profile has been successfully downloaded and you arrive in the supported country, the eSIM will automatically connect to mobile data, such as 3G, 4G, or 5G. From that point on, you can browse the web and use apps smoothly and independently without relying on Wi-Fi anymore.

5.4. How Many eSIMs Can One Phone Store And How Many Numbers Can Be Used At The Same Time?

You can absolutely store multiple backup eSIM profiles on your phone, but the number of networks that can be active at the same time will be limited.

Storage capacity: Most modern phones allow you to store around 5 to 8 eSIM profiles in advance, while newer models may support even more.
Simultaneous use: Even if you store multiple eSIMs, you can usually activate a maximum of 2 networks at the same time. This can be 1 physical SIM plus 1 eSIM, or 2 eSIMs at once on iPhone 13 models and later. The remaining eSIMs will stay inactive until you switch them on.

By now, you should have a clear understanding of how to activate eSIM through the steps above. You can leave behind the inconvenience of physical SIM cards and stay ready to connect to the Internet wherever you go.
