T-Mobile customers can convert their physical SIM to an eSIM directly on their compatible device without visiting a store. This process requires a compatible unlocked device and a stable Wi-Fi connection, and it works for both postpaid and prepaid accounts.
Before you begin: compatibility and requirements
Your device must be eSIM compatible and unlocked if it was not originally purchased from T-Mobile. Compatible iPhones include iPhone XS or newer, running iOS 15.4 or higher for Quick Start conversion. Compatible Android devices generally include flagship models from 2020 onward, such as Samsung Galaxy S Series and Note 20 and above, and Google Pixel 7 and above. A Wi-Fi connection is required during the eSIM activation process.
Convert your physical SIM to eSIM on an iPhone
To convert your physical SIM to an eSIM on the same iPhone, follow these steps:
- Open the Settings app.
- Tap Cellular.
- Tap Convert to eSIM.
- Follow the on-screen prompts to complete the conversion.
If you are setting up a new iPhone, you can use Quick Start to transfer your existing physical SIM to an eSIM on the new device. Turn on the new iPhone and bring your old iPhone nearby. Follow the Quick Start prompts, select "Transfer from another iPhone," choose the phone number linked to your physical SIM, tap "Transfer Number," and confirm on your old iPhone (e.g., by double-clicking the side button).
Convert your physical SIM to eSIM on a Samsung Galaxy
To convert your physical SIM to an eSIM on a Samsung Galaxy device, follow these steps:
- Open the Settings app.
- Tap Connections.
- Tap SIM manager.
- Tap the SIM you wish to convert.
- Tap Convert to eSIM.
- Choose "Convert eSIM" and follow the prompts.
On the same Samsung Galaxy device, the specific path is Settings > Connections > SIM manager > SIM > Convert to eSIM, then choose 'Convert eSIM' (e.g., S23+).
For other Android devices, the path may vary but typically involves Settings > Network & Internet > Add SIM > Set up an eSIM, then selecting T-Mobile and following the prompts.
How to use the T-Mobile app for SIM conversion
For existing T-Mobile postpaid customers, you may be able to manage SIM transfers or activations through the T-Life app by selecting the Account tab, choosing the line, and then "SIM transfer or activation." This is a convenient alternative to using device settings, especially when you are already managing your account, and it helps streamline the process of activating phones and SIM cards on any carrier.
For T-Mobile Prepaid accounts, you can activate an eSIM via the T-Mobile Prepaid eSIM app (no QR code required). For T-Mobile Prepaid accounts, you can also activate an eSIM by visiting prepaid.t-mobile.com and following the activation steps, which may involve scanning a QR code.
Finalizing and testing your new eSIM
After the eSIM profile downloads and activates, confirm the eSIM profile has downloaded by checking your device's cellular settings. If you miss an auto-discovery notification for eSIM download, you can often access it by dragging down the status bar. To verify functionality, make a test call or use mobile data before removing the physical SIM card.
Frequently Asked Questions
Can I keep my same phone number after converting to eSIM?
Yes. Converting your physical SIM to an eSIM on the same device or during a new phone setup transfers your existing T-Mobile phone number to the eSIM profile.
What if my device is locked to another carrier?
Your device must be unlocked to use a T-Mobile eSIM. If your device is locked to another carrier, you will need to have it unlocked before you can convert your physical SIM to an eSIM on T-Mobile.

Yes. T-Mobile can provide a new physical SIM card if you decide to switch back. Contact T-Mobile customer support or visit a store to request a physical SIM replacement.
Will converting to eSIM affect my prepaid account balance or plan?
No. Converting your physical SIM to an eSIM does not change your prepaid account balance, plan details, or billing. Your service continues as before, just with an eSIM instead of a physical SIM.
How do I know if my device is eSIM compatible?
Check your device's specifications on the manufacturer's website or in your device settings. For iPhones, models iPhone XS and newer support eSIM.
