169 Comments about my post on How to Subsidy Unlock Samsung SGH-T919 (Behold) and it appears that T-Mobile Customer Care and AT&T Technical Support are of no help.
So I created this post to show you the steps to access the Network Configuration menus.
Now I cannot help you to figure out what the network configuration is for your particular mobile operator, you will need to obtain that yourself from either the Technical Support or use Google!
Click on the Phone icon
Using the keypad, press: *#6984125*#
This will automatically bring you to the next step.
In the Admin setting, click on Network & call settings
In the Network & call settings menu, click on Connections
In the Network profiles menu, you will need to configure the Browser, MMS, Java, and IM. The _TMO_DS_ setting holds the Internet connection settings. The easiest is to click on Create and fill in all the fields based on your network configuration.
