How to Activate a Mint Mobile SIM Card or eSIM

Quick Answer: You can activate your Mint Mobile SIM card or eSIM using the Mint Mobile app. Enter your 11-digit ACT code, choose whether to keep your number or get a new one, then install your SIM or eSIM and complete the setup.

To activate a Mint Mobile SIM card or eSIM is a simple process, but it’s easy to get stuck if you’re missing your ACT code or don’t know when to insert the SIM. If you’re switching from another carrier, timing also matters if you want to keep your current phone number.

I wrote this guide after several readers and YouTube viewers asked why their Mint Mobile activation stopped during setup. Some also wanted to know when they should cancel their old carrier. I reviewed Mint Mobile’s activation process and combined it with common user questions to explain each step in simple language.

This guide is for anyone activating a new Mint Mobile physical SIM card or eSIM, whether you’re getting a new number or transferring your existing one.

Before You Activate Your Mint Mobile SIM

Before opening the Mint Mobile app, make sure everything is ready.

You’ll need:

  • An unlocked phone.
  • Your 11-digit ACT code.
  • A stable Wi-Fi connection.
  • Your carrier account number and transfer PIN if you’re keeping your current number.

One important tip is to keep your existing mobile service active until the number transfer is complete. Canceling too early can delay the transfer or cause you to lose your phone number.

Method: Activate Using the Mint Mobile App

The easiest way to activate your Mint Mobile service is through the official Mint Mobile app.

Follow these steps.

Step 1: Prepare Your Phone

Before starting the activation:

  • Confirm that your phone is unlocked.
  • Keep your ACT code ready.
  • Do not cancel your current mobile service.
  • Have your physical SIM or eSIM information available.

If you’re using a physical SIM, you’ll insert it later during the setup.

If you’re using an eSIM, you’ll install it after completing the activation process.

Step 2: Download the Mint Mobile App

Connect your phone to Wi-Fi before downloading the app.

Then:

  • Open the App Store on iPhone or the Google Play Store on Android.
  • Search for the Mint Mobile app.
  • Download and install it.
  • Open the app.
  • Tap Activate Your SIM.

The app will guide you through each step.

Step 3: Enter Your ACT Code

Mint Mobile requires an 11-digit ACT code to begin activation.

You can find it:

  • On the SIM package if you’re using a physical SIM.
  • In your activation email if you’re using an eSIM.

Enter the code carefully before continuing.

Step 4: Choose Your Phone Number

Next, you’ll decide whether to keep your existing phone number or get a new Mint Mobile number.

Keep Your Current Number

If you’re transferring your number, you’ll need:

  • Your current phone number.
  • Your ZIP code.
  • Your existing carrier’s account number.
  • Your Number Transfer PIN.

Mint Mobile will use this information to move your number from your current carrier.

Get a New Number

If you don’t want to transfer your current number, simply choose the option to receive a new Mint Mobile phone number.

This usually makes activation even faster.

Step 5: Complete Your Mint Mobile Account

You’ll now be asked to finish creating your Mint Mobile account.

Enter:

  • Your name.
  • Your email address if requested.
  • A secure account password.

Review your information and submit your activation request.

Step 6: Install Your SIM Card or eSIM

The next step depends on which type of service you’re using.

Physical SIM Card

If you’re using a physical SIM:

  • Insert the Mint Mobile SIM card into your phone.
  • Restart your device.

Your phone should begin connecting to the Mint Mobile network.

eSIM

If you’re using an eSIM:

  • Scan the QR code provided by Mint Mobile.
  • Follow the on-screen instructions.
  • Complete the eSIM installation.

Most supported phones finish this process within a few minutes.

Step 7: Complete the Final Setup

After activation, your phone should connect to the Mint Mobile network automatically.

If you’re using an Android phone, you may need to update the APN settings for mobile data.

If your phone doesn’t connect immediately:

  • Restart your phone.
  • Wait a few minutes for the network to activate.
  • Check that your SIM or eSIM was installed correctly.

Most activation issues are resolved after a restart.

Common Mint Mobile Activation Problems

If your activation doesn’t work right away, check these common issues.

  • The ACT code was entered incorrectly.
  • Your phone is still locked to another carrier.
  • Your number transfer is still processing.
  • Your SIM card wasn’t inserted correctly.
  • Your eSIM installation wasn’t completed.

If everything appears correct and your service still isn’t active, Mint Mobile customer support can help complete the process.
