How do I turn on data remotely? Need help ASAP.

So I forgot my phone's pin (Galaxy Nexus) and yes, I am locked out. I can change the pin through Android Device Manager but it won't push the request to my phone since data is turned off. I do not want to reset my device so how I can turn on data without access to the phone? There's gotta be a way.

Counting on you guys. Thanks in advance.
