To switch phones with Mint Mobile while keeping your current number and plan, you have two main paths: moving your physical SIM card to the new device, or transferring your service to an eSIM through the Mint app. The right choice depends on whether your new phone supports eSIM, and the entire process is designed so you can switch phones Mint Mobile without contacting customer support or changing your plan.
How to switch phones with Mint Mobile: The two paths for existing customers
As an existing Mint Mobile customer, you are not starting a new account when you get a new phone. You are simply moving your existing line to different hardware. There are two ways to do this, and the one you use depends entirely on the phone you are moving to. The first method is a physical SIM swap, where you take the small SIM card out of your old phone and put it into your new one. The second method is an eSIM transfer, which uses the Mint Mobile app to download your service profile directly onto a new phone that supports eSIM technology. The app-based eSIM path is the more modern option, and the menu sequence you need is confirmed: open the Mint app, go to Account, then Order Replacement SIM, then Get an eSIM, then choose This is my new device, and finally tap Order now.
Before you switch
Mint Mobile is an MVNO that doesn't own its own cellular network infrastructure but partners with major carriers. Mint Mobile operates on the network infrastructure of T-Mobile. Mint Mobile offers prepaid plans that can be customized based on your needs, with no long-term contracts. Mint Mobile provides unlimited nationwide talk and text, mobile hotspot capabilities, and Wi-Fi calling. You can bring your own phone or purchase a new one directly from Mint Mobile. You have the freedom to switch phones, change plans, or cancel your service at any time. Before you move your service, take a few minutes to prepare. Back up your old phone completely, including contacts, photos, messages, and any app data you want to keep. This is not a Mint-specific step, but it is the most common way people lose data during a phone change. Next, confirm your new phone is eSIM compatible if you plan to use that method. The Mint app gives you a simple indicator: if the Get an eSIM option is not available in the app, your phone does not support eSIM, and you will need to use the physical SIM card instead. Check device compatibility with Mint Mobile's network by checking the device's specifications or contacting Mint Mobile's customer support. Also, make sure your new phone is unlocked from any previous carrier and that it has enough battery charge to complete the setup process without dying mid-transfer. Gather necessary information before switching: Mint Mobile account details, phone number, account PIN, and any other relevant information provided by the carrier. Factory reset your old phone to remove all personal data and accounts if selling or giving it away.
Switch using a physical SIM card
Using a physical SIM card is the most straightforward way to move your Mint Mobile service to a new phone. This method works for any phone that accepts a physical SIM, and it does not require any interaction with the Mint app or website.
- Power off both your old phone and your new phone.
- Locate the SIM card tray on your old phone. Use the SIM ejector tool or a small paperclip to open it.
- Remove the SIM card from the old phone's tray.
- Locate the SIM card tray on your new phone and insert the same SIM card into it.
- Power on your new phone.
Once the phone boots up, it should automatically connect to the Mint Mobile network. You do not need to activate anything or enter any codes. Make a test call, send a text, and try a data connection to verify service is working. If everything works, you are done. This is the simplest way to switch phones Mint Mobile, and it preserves your number and plan exactly as they were.
Switch using an eSIM
If your new phone supports eSIM, you can transfer your service without ever touching a physical SIM card. This is done entirely through the Mint Mobile app, and the process is designed for existing customers moving to a new device.
- Make sure the Mint Mobile app is installed on your new phone. If it is not, download it from your phone's app store.
- Open the Mint Mobile app and log in to your account.
- Tap on Account in the menu.
- Select Order Replacement SIM.
- Choose Get an eSIM.
- When asked about the device, select This is my new device.
- Tap Order now to complete the eSIM download request.
After you tap Order now, the app will push the eSIM profile to your new phone. Follow the on-screen prompts to install the profile, then restart your phone if prompted. Your number and plan move with the eSIM, so there is no separate number transfer step. If you do not see the Get an eSIM option in the app, your phone is not eSIM compatible, and you will need to use the physical SIM method instead.
Keep your number when switching
When you switch phones on an existing Mint Mobile line, your phone number stays with your account, not with the physical device. Moving your SIM card or downloading an eSIM to a new phone does not change your number in any way. The number is tied to your Mint Mobile account, and the SIM or eSIM simply tells the network which device to route your calls and texts to. For number transfer, check eligibility that your current mobile number is eligible for porting from other carriers. For number transfer, gather your current carrier account number, PIN, and any additional details required by your current carrier. Number transfer typically takes a few hours to complete, but in some cases may take up to 24 to 48 hours. You may see an option in the activation flow that says Keep Your Current One, but this only appears if you are prompted during an activation process. For a simple phone swap on an existing line, you are not activating a new line, so you will not see that prompt. Your number is already on your account, and it stays there regardless of which phone you use.
Troubleshooting after switching
Most phone switches go smoothly, but if you run into issues, here are the common fixes. If you have no service after a physical SIM swap, power off the phone, remove the SIM card, and reseat it firmly in the tray. Make sure the tray is fully closed. If you still have no service, check your APN settings. Mint Mobile uses specific access point name settings for data, and a new phone may not have them configured automatically. For eSIM downloads, the most common issue is a slow or unstable Wi-Fi connection. Make sure you are on a strong Wi-Fi network before starting the eSIM download, and do not close the app until the profile is fully installed. If the eSIM download fails or the profile does not activate, restart your phone and try the process again. If you still cannot get service, contact Mint Mobile support directly. They can verify your account status and push a new eSIM profile or help you troubleshoot the SIM card. The support team can also confirm whether your specific phone model is fully compatible with the Mint Mobile network, especially if you are using a phone that was not originally sold by Mint.
Frequently Asked Questions
Do I need to buy a new SIM card to switch phones?
No, you do not need a new SIM card if your current physical SIM fits the new phone. If the new phone requires a different SIM size, you can request a replacement SIM from Mint, or use the eSIM method if your phone supports it.
Will switching phones change my Mint Mobile plan?
No, switching phones does not affect your plan. Your plan, data allowance, and billing cycle remain exactly the same. You are only changing the device that uses the line.
Can I switch back to my old phone later?
Yes, you can switch back at any time. Just move the physical SIM back to the old phone, or download the eSIM profile to it again through the Mint app. Your number and plan will work on either device.
What if my new phone is locked to another carrier?
A locked phone will not work with Mint Mobile. You must have the phone unlocked by the original carrier before you can use it with your Mint SIM or eSIM. Contact the original carrier to request an unlock.
How do I set up Mint Mobile on a brand new phone that has never had service?
If you are setting up Mint Mobile on a new phone for the first time, you would follow the activation flow in the app, which asks whether you want to get a new number or keep your current one. That is a different process from switching an existing Mint line, which is just a SIM or eSIM move.
