Switching from a physical SIM to an eSIM can make your device setup more flexible, travel-friendly, and future-proof. But not every phone or carrier supports SIM to eSIM conversion. Some users may need to request a fresh eSIM from their provider instead.
This guide walks you through how to convert your SIM to eSIM on both iPhone and Android devices, what to expect, and what to do if your carrier doesn’t support conversion.
What You Need Before Converting to eSIM
An eSIM-compatible device Most iPhones from XS onward, newer Google Pixels, and Samsung Galaxy S/Z series support eSIM. Check your phone model to confirm.
Carrier support for eSIM conversion Not all carriers allow converting a physical SIM into an eSIM. Some may only offer new eSIM activations.
Carrier app or QR code If “Convert to eSIM” doesn’t appear in your phone settings, you’ll need a QR code or your carrier’s app.

Apple makes it very simple if you're staying with the same carrier.

Go to Settings > Cellular

This only works if your carrier supports automatic conversion. If you don’t see the option, use your carrier app or contact support.

Carrier-Specific SIM to eSIM Conversion
Here’s how the process works for popular US carriers:

Use the myAT&T app to convert to eSIM or request a QR code online.
You can also visit a store or contact support to generate the QR code.
T-Mobile
Use the T-Mobile app or call support to convert your existing number to eSIM.
Alternatively, walk into a store and request eSIM activation.
Verizon

You’ll get a QR code for activation or instructions to switch via the app.
What Happens After You Convert?
Your physical SIM will be deactivated
Your number and plan stay the same
You can remove or repurpose the SIM slot for travel or dual SIM usage
Why Convert to eSIM?
Faster activation – No need to wait for physical delivery or store visits
Dual SIM flexibility – Use a travel eSIM like Eskimo alongside your home number
Fewer moving parts – No more swapping or losing SIM cards
Eco-friendly – Reduces plastic waste
Common Issues During eSIM Conversion
Conversion option missing? Your carrier might not support automatic conversion. Use QR method or call support.
Activation fails? Ensure your phone is updated and unlocked. Restart and try again.
Can’t scan QR code? Use manual activation details provided by your carrier.

Once your number is running on eSIM, your phone’s SIM tray is now free. That means you can insert a local SIM while abroad or better yet – pair your main number with an Eskimo global travel eSIM. It installs in minutes and works across 130+ countries, no roaming fees, no hassle.
What if I don’t see “Convert to eSIM” on my iPhone?
Your carrier might not support automatic conversion. Contact your carrier or use the QR code/manual method.
Can I switch back to a physical SIM?
Yes, but you’ll need a new SIM card. Your eSIM will be deactivated, and your carrier can issue a new SIM with the same number.
Does converting to eSIM cost money?
Some carriers may charge a one-time fee. Many, like T-Mobile and Google Fi, offer free eSIM conversions.
Will I lose my data or number?
No. The process preserves your number and cellular plan. Data and apps on your phone remain untouched.
How many times can I reinstall an eSIM?
Eskimo allows up to 5 re-installations per eSIM, but limits vary by carrier. Always confirm with them.
