Yes, you can switch from AT&T to Mint Mobile without losing your phone number, as long as you keep your AT&T service active, have your transfer details ready, and complete the activation correctly.
Over the past few months, I’ve noticed more people asking the same question on my blog and YouTube videos: “Is switching from AT&T to Mint Mobile really as easy as they say?” Most aren’t worried about changing carriers. They’re worried about losing their phone number or getting stuck with activation problems.
To find the answer, I went through Mint Mobile’s activation process, reviewed AT&T’s number transfer requirements, and checked the latest guidance from both companies. If you’re planning to make the switch, this guide walks you through each step so you know what to prepare and what to avoid before moving your service.

Who Is This Guide For?
This guide is for:
● AT&T customers switching to Mint Mobile
● Anyone who wants to keep their current phone number
● People bringing their own unlocked phone
● Anyone looking for a lower monthly phone bill
What You Need Before Switching
Before starting the transfer, gather the information you’ll need.
Have these details ready:
● Your AT&T account number
● Your Number Transfer PIN
● Your billing ZIP code
● An unlocked, compatible phone
Having this information ready helps avoid most number transfer problems.
Step 1: Prepare Your Phone
First, decide whether you’ll bring your current phone or buy a new one.
If you’re bringing your own phone, make sure it is:
● Fully paid off
● Unlocked
● Compatible with Mint Mobile’s network
If your phone doesn’t meet these requirements, you’ll need to unlock it or purchase a compatible device before activating your Mint service.
Step 2: Transfer Your Number or Get a New One
You can either keep your current AT&T number or choose a new one.
If you’re transferring your existing number:
● Keep your AT&T service active.
● Do not cancel your account before the transfer finishes.
● Turn off Wireless Account Lock.
You’ll also need:
● Your AT&T account number
● Your billing ZIP code
● Your Number Transfer PIN, which you can request by dialing *7678
If you’d rather get a new phone number, simply enter your ZIP code during Mint Mobile activation.
Step 3: Choose the Right Mint Mobile Plan
Mint Mobile offers several prepaid plans.
Current options include:
● Plans starting at around $15 per month
● Unlimited plans starting around $30 per month
● Prepaid options for 3, 6, or 12 months
In most cases, longer prepaid plans offer the lowest monthly price.
Choose the plan that matches how much data you normally use.
Step 4: Activate Your Mint Mobile Service
Once your SIM kit arrives, you’re ready to activate your service.
Here’s what to do:
● Insert your Mint Mobile SIM card.
● Download the Mint Mobile app.
● Follow the activation instructions.
● Choose whether to transfer your current number or receive a new one.
● Create your Mint Mobile account.
The app walks you through each step, making activation straightforward for most users.
Important Tips Before You Switch
These simple steps can prevent common activation problems.
● Don’t cancel your AT&T service before your number transfers.
● If you’re transferring multiple lines, move secondary lines first.
● Transfer the primary account holder’s number last.
● Make sure Wireless Account Lock is disabled.
During the process, AT&T may send you a confirmation message. Approve the request so your number transfer can continue.
What Happens After Activation?
Once activation is complete:
● Your phone number transfers automatically.
● Your AT&T service usually cancels automatically after the transfer.
● Most number transfers finish within a few hours, although some may take longer depending on the situation.
You can continue using your AT&T SIM until the transfer is complete.
