Default ussd code running invalid mmi code


I just migrated from Mexico to USA a couple of months ago and well i bought a set of unlock codes for my LG Optimus Black. The set of instructions that I've received on ample sites was to use 2945#*920# code to be able to input my unlock code but I just keep receiving "ussd code running invalid mmi code" in response. I just recently upgraded my phone as well from 2.2 to 2.3.4. I would highly appreciate if someone can give me a bit of insight with my phone so I can unlock it. The original phone company for my phone is "Telcel". Idk if that helps any.

Many thanks in advance,
