Unlocking a phone enables you to use your phone on a compatible carrier’s network.

Phone Requirements

Dr.Fone - Screen Unlock (Android) This is one of the best phone unlocking software you can use to. Fast Network Unlock Codes! 100% Guaranteed, Unlock Samsung, BlackBerry, LG, Nokia, Motorola, iPhone & HTC Cell Phones by Unlock Codes.

The phone must be a Metro by T-Mobile Phone.

Note:

Unlocked phones can only use networks of the same type. For example, an unlocked GSM-only phone will only work with another carrier’s compatible GSM network. It will not work with another carrier’s CDMA network.
Unlocking your phone does not guarantee that the phone will fully work with all of a competing carrier’s services and features.

Service Requirements

Your handset must have had active service for a minimum of one hundred eighty (180) consecutive days from the individual phone’s activation date.

Note: For warranty exchange handsets, the original phone’s activation date counts as the beginning of the one hundred eighty (180) days, not the activation date of the warranty exchange handset.

Frequently Asked Questions

Why do I need an unlock code for my phone?

When can I request the unlock code for my phone?
You can request the unlock code after 180 consecutive (continuous) days of phone service with Metro by T-Mobile.

When does the service requirement (180 consecutive days) start?
The service requirement begins from you phone’s activation date. The first day your phone is active with Metro by T-Mobile counts as day 1. Please note that your phone’s activation date is different from your account’s activation date.
Note: For warranty exchange phones, the activation date is the date of the phone you originally purchased, not the activation date of your warranty exchange handset.
