Can you verify that your operator has 3G available at the location where you are?
Also check that you not in flight mode (airplane picture at the top of the display)?
Once when powering on my phone, I bypassed the SIM code entry, which put my external networking off. (I think WLAN still worked).
Other than these, the connection should be either automatic, or by selecting from the connection/sound volume/bluetooth menu, which you get by touching the top of the screen.
If you are in the US I had a similar problem, all the US phones connect to 3G by default no configuration needed, but N9 was a bit different. I ma on T-Mobile US, got my N9 went to store, acquired a new Micro SIM, popped into my N9, couple of seconds later, it says T-mobile, can make calls, but wait what no 3G??
So heres what I did,
Go to Settings-->Internet Connection
Swipe on Internet Connection
Touch Connect to internet, click on T-Mobile web2go (maybe something else in your case), viola you have 3G now (mine says 3.5 not sure why)
Then touch/click Edit networks and make sure you mark your 3G internet connection as 'Automatic'
Hope this helps!!
