You're tired of swapping tiny plastic SIM cards. Maybe your SIM slot is damaged. Or you’re travelling soon and don’t want to rely on unstable roaming. You’ve heard of eSIM, but figuring out how to switch from a physical SIM feels unclear.
This guide gives you exactly what you need. A step-by-step explanation whether you’re on iPhone, Android, or just switching for convenience or travel.
What Is an eSIM and Why Are So Many People Switching?
eSIM (Embedded SIM) is a digital SIM built into your phone—no physical card is required. It works just like a physical SIM but is activated through a QR code or carrier app. You can store multiple eSIM profiles on one device and switch between them. It’s ideal for travellers, digital nomads, and anyone managing dual lines.
Why the shift?
- No risk of losing or damaging SIM cards
- Easier to switch carriers or plans—especially while abroad
- Perfect for phones with no SIM slot (like the iPhone 14 US model)
- Faster activation and fewer moving parts
How to Convert a Physical SIM to eSIM on iPhone
Important: Not all carriers support SIM-to-eSIM conversion. Confirm with your carrier first.
Defy Mobile currently does not support SIM-to-eSIM transfer. You’ll need to purchase an eSIM plan separately and install it using the QR code provided.
If your carrier supports it, here’s how to convert:
- Go to Settings > Cellular
- Tap your physical SIM line
- Select Convert to eSIM (you’ll only see this option if your carrier allows it)
- Tap Convert Cellular Plan and confirm
- Wait for your eSIM to activate. Your physical SIM will deactivate automatically
Tip: Stay connected to Wi-Fi during the conversion process to avoid interruptions.
How to Convert a Physical SIM to eSIM on Android?
It all depends on the make,model, and variant of your device, but here’s the general method for Android phones (Samsung, Google Pixel, etc.):
- Open Settings
- Tap Connections > SIM card manager (or similar)
- Look for Convert to eSIM or Add eSIM
- If your physical SIM is eligible, follow the on-screen instructions
- If not, your carrier may offer eSIM via QR code or app activation
Again, Defy Mobile requires you to install your eSIM plan via a QR code, which will be emailed after purchase.
Devices That Support eSIM Conversion
Not every phone supports converting a SIM to eSIM, even if it’s eSIM-compatible. Below are popular models where conversion is possible (based on current global carrier capabilities):
- iPhone XS, XR, and newer (iPhone SE 2nd gen and above)
- Google Pixel 4 and newer
- Samsung Galaxy S20 and newer
- Motorola Razr (2020+), some Xiaomi and Oppo models
Check your phone’s settings or manufacturer support page to confirm.
Common Issues (And How to Avoid Them)
Here are some of the biggest snags users run into during the switch:
- No “Convert to eSIM” option in the settings
- → Your carrier doesn’t support this yet. Request a QR code or switch to an eSIM-friendly provider.
- Activation failed or stuck
- → Restart your phone, ensure you have Wi-Fi, and try again. If the issue persists, contact your carrier’s support.
- Lost service after conversion
- → Sometimes, the physical SIM gets deactivated before the eSIM kicks in. Give it a few minutes, or re-insert the physical SIM if needed.
Why Travelers Are Choosing eSIM Over Physical SIM?
- Instant connectivity in any country—no hunting for a local SIM
- Avoid roaming charges and get local data rates instantly
- Manage multiple country profiles without carrying extra SIM cards
- No risk of losing tiny SIM ejector pins or cards mid-trip
Defy Mobile offers travel-ready eSIM plans for over 200+ destinations, with QR activation and real-time support.
When Should You Stick With a Physical SIM?
- If your phone doesn’t support eSIM
- If you’re using a carrier that hasn’t enabled eSIM switching
- If you frequently change phones that don’t support eSIM reactivation
But for most modern users—especially travellers and dual-line users—eSIM is the simpler, faster, and more intelligent choice.

FAQs
Can I convert my physical SIM to eSIM without contacting my carrier?
No. Most carriers must enable or authorise the conversion process. If unsupported, you’ll need to request a new eSIM.
Does Defy Mobile support physical SIM to eSIM conversion?
Currently, no. Defy Mobile requires you to purchase a new eSIM plan and activate it via a QR code.
Can I use both eSIM and physical SIM on the same phone?
Yes—if your phone supports dual SIM (eSIM + physical). This is useful for managing separate numbers or data plans.
Will my phone number change if I switch to eSIM?
No. If you're converting via your carrier, your number remains the same unless you request a new one.
