How Do I Enter an Unlocking Code on a T-Mobile Dash Phone?

T-Mobile is the exclusive dealer of the T-Mobile Dash, a smartphone device manufactured by HTC. T-Mobile locks the subscriber identity module (SIM) in the Dash to prevent you from inserting another network's SIM card and using the phone on another network. To unlock the SIM, you need the unlock code. You can ask T-Mobile for a free one or buy one from an unlock code retailer.
