How to Check if Your Phone Supports eSIM

Before you try to convert SIM to eSIM, you need to know if your phone even supports eSIM in the first place. Not all devices are ready for it — especially older Android models or budget phones.

Method 1: Use the *#06# Code

• Dial *#06# on your phone.
  
• If you see an “EID” number, your device likely supports eSIM.
  
• No EID? Your device might not be compatible.
  

Method 2: Check via Settings

On iPhone:

Go to Settings → Mobile Data → Add eSIM.
If the option is visible, your iPhone supports eSIM.

On Android:

Go to Settings → Connections → SIM Manager or search “eSIM” in Settings.
If you see an option to add eSIM, your device is compatible.

Yes, it’s possible to convert SIM to eSIM online — and it’s surprisingly simple once you know where to look. Different carriers may use slightly different processes, but most follow the same steps.

Step 1: Check Carrier Support

Not all telecom providers offer online eSIM conversion. Most major global players like:

• T-Mobile
  
• AT&T
  
• Verizon
  
• Vodafone
  

offer a way to switch via their website or app.

Step 2: Log In to Your Carrier Account

Use your telecom provider’s mobile app or web portal. Go to the SIM or device section and look for “Convert SIM to eSIM” or “Get eSIM.”

If it asks for device details like EID or IMEI, use the *#06# code to fetch them.

Step 3: Receive Your eSIM QR Code

Once verified, your carrier will email or display a QR code on the screen. This is your eSIM activation key.

Step 4: Scan the QR Code on Your Phone

On your device, go to:

• iPhone: Settings → Mobile Data → Add eSIM
  
• Android: Settings → Connections → SIM Manager → Add eSIM
  

Then scan the QR code provided by your carrier.
