If you're looking to unlock the phone & text function on your phone, there's a ton of hypersim unlocks that you can use.
simable.com is good. Just punch a small hole in your simcard & slip it in with the hypersim & start up your phone.
But if you're looking to unlock the internet & email, so far, the hypersim's haven't worked for me.
Are you using the phone in the US?
