Meta Description: Locked out of your MetroPCS (Metro by T-Mobile) SIM card? Find your PUK code using the SIM card holder or by calling customer service. Learn the steps to unlock your SIM card and avoid permanent lock-out.
If your phone is displaying a “SIM Locked” or “Enter PUK Code” message, it means you have entered the incorrect SIM PIN multiple times, and your SIM card has been temporarily disabled as a security measure. The PUK code (Personal Unblocking Key, or Pin Unlock Key) is an 8-digit, unique code tied to your SIM card that allows you to reset your PIN and regain access to your Metro by T-Mobile (formerly MetroPCS) service.

It is critical to find your correct PUK code immediately, as entering the wrong PUK code 10 times will permanently lock your SIM card, requiring a replacement.
This guide outlines the safest and most reliable methods for MetroPCS customers to retrieve their PUK code and successfully unlock their SIM card.
What is a PUK Code and Why Do I Need It?
The PUK code is a crucial security feature that exists solely to unlock your SIM card after a security lockout.
- Trigger: The lock is triggered automatically when the device’s standard 4-digit SIM PIN is entered incorrectly three times.
- Function: The PUK code acts as a master key to override the SIM PIN security and allows you to establish a brand-new PIN.
- The Danger: If you enter the wrong PUK code 10 times, the SIM card will be permanently disabled by the network and must be replaced (and potentially paid for) at a Metro by T-Mobile store.
Part 1: Three Methods to Retrieve Your MetroPCS PUK Code
You must be the primary account holder or an authorized user to obtain the PUK code for security reasons.
Method 1: Check the Original SIM Card Holder (Fastest Method)
If you still have the original piece of plastic that your SIM card (or eSIM details) came attached to when you activated the line, your PUK code should be printed on it.
- Location: Look on the back or side of the card, often labeled “PUK” or “PUK1.”
Method 2: Contact Metro by T-Mobile Customer Service
If the packaging is lost, you must contact customer care. You cannot retrieve the PUK code from the MyMetro app or the website due to security restrictions.
- Call Support: Call Metro by T-Mobile Customer Service from a landline or another working phone.
- Customer Service Number: 1-888-8-METRO-8 () or 611 from a working Metro phone.
- Verify Account Ownership: Be prepared to provide your full name, mobile number, and the 6-15 digit Account PIN to confirm your identity.
- Request the Code: Once verified, the representative will retrieve the 8-digit PUK code associated with your locked SIM card.
Method 3: Visit a Retail Store (As a Last Resort)
If you cannot call customer care, you can visit a Metro by T-Mobile store.
- Requirement: Bring a valid photo ID to allow the store representative to verify your identity and access the account to retrieve the PUK code. Be aware that some authorized dealers may be unable to assist or may attempt to charge a fee for a new SIM card.
Part 2: How to Use the PUK Code to Unlock Your SIM
Once you have the correct 8-digit PUK code, follow these steps immediately and carefully:
- Enter the PUK Code: On the locked device’s screen (which should prompt “Enter PUK Code”), carefully input the 8-digit PUK code.
- Enter New PIN: The phone will then prompt you to create a new 4-digit SIM PIN. Choose a number you can easily remember.
- Confirm New PIN: Re-enter the new PIN to confirm.
Your SIM card should now be successfully unlocked, and your phone will register back on the Metro by T-Mobile network.
Frequently Asked Questions (FAQ)
What happens if I use all 10 PUK attempts?
If you enter the incorrect PUK code times, the SIM card will be permanently locked (PUK Exhausted). Your only option will be to purchase and activate a new SIM card from Metro by T-Mobile, resulting in potential fees and the hassle of switching SIMs.
Is the PUK code the same as the Network Unlock Code (NUC)?
No. The PUK code unlocks the SIM card to allow it to be used with the Metro by T-Mobile service. The Network Unlock Code (or Device Unlock Code) unlocks the phone handset itself, allowing it to be used with any carrier’s SIM card. You must meet separate eligibility requirements (typically 365 days of service) to unlock the device from the Metro network.
Will the PUK code appear on my online Metro account?
No. For high-level security, the PUK code is typically not displayed in your online My Account portal or the MyMetro App. It is only provided directly by a customer service agent or found physically on the SIM packaging.
