Switching Providers too soon?

How soon after switching providers can you switch to another?

To elaborate: I just switched to Freedom Mobile from Virgin due to me cutting it too close to my data cap every month, but Freedom's network isn't really working out for me. Is it possible to switch providers three times within a two week span? I'm not tied down by any terms or tabs.

Edit:

Called Virgin and said That I could resume my previous plan (3gb for $55) for an administrative fee of $35. Not sure I got to keep my $10/month credit that I got at sign up though. Overall, I'm happy.
