I have the globalsim too. The sim pin will be included in the confirmation email that also includes your phone number. It's NOT anywhere on my sim card. If it's on yours, verify that it's the same as the one in the email...well, it's too late now. The sim pin is also what you use as the password when you login. Once you login, you can also see your PUK and anything else associated with your sim.

Here is an excerpt from the email I received when I bought mine...
