If you're trying to activate a Virgin Mobile Android mobile phone (e.g. Motorola Triumph, Samsung Intercept. etc.) don't panic if you get error code 06-07-5910:
Because, there is a simple solution:
Getting this error wasn't your fault, and it doesn't mean you're dumb. On the contrary, it suggests you're a clever phone-nerd: You figured out, that by activating WiFi, you could play with your new phone immediately, without having to activate it first. There's no shame in wanting to play with it. ;-)
So have fun!
Note: Error codes are very fussy. if you have a "similar" error number -- but not the exact numeric code shown above -- turning off WiFi probably won't help you. You'll need to keep searching the web for the precise error code your phone displayed.
