How to Unlock MetroPCS Phones for Sprint Treo

By Alex Zang

Most phone carriers such as Sprint, Verizon, and T-Mobile use code division multiple access (CDMA) to allow users to make phone calls and transmit data. If a customer doesn't pay his bill or cancels his account, the cell phone provider can also use the mobile phone's CDMA number to shut down the phone, preventing it from being used. In the summer of 2008, MetroPCS announced that they would reprogram the phone of any Sprint customer who decided to switch carriers from Sprint to MetroPCS. This allows the Sprint customer to keep the same cell even after switching carriers.

Step 1

Find your phone's model number. It should be underneath the battery on a sticker that says "Model Number."

Step 2

Check to see if your phone is compatible with the MetroPCS program. To do that, click on the link located in the resource section, then click on your phone's brand logo on the right hand side of the screen. A small window will pop up that lists all of the model numbers that are compatible. If your phone is there, you can switch over.

Step 3

Find the nearest MetroPCS store by clicking on the link in the resource section and entering your zip code in the box. Click "Submit." As of February 2011, MetroPCS does not offer service to New York, western and northern Michigan, Bossier City Louisiana, and the Boston area. MetroPCS does offer service in all other areas of the continental U.S.

Step 4

Bring your cell phone to the MetroPCS store. Unfortunately, you can't program it to become a MetroPCS number yourself. As of February 2011, the cost to reprogram your cell phone is $10. After you've paid the $10, your phone will be unlocked as a MetroPCS phone.

Cancel any contract you have with Sprint.
