Recharged Prepaid Sim

My Orange prepaid sim chip expired from my last trip 2 months ago. I recharged it on-line today while in USA. When I go back to Romania this week will I need to do anything on my cell phone for it to work like using the Star or Pound keys? Or will it automatically work once the signal is located on my cell phone?

It should work fine, mine did when I did the same thing a week ago.

Update:  Connected automatically when we got signal.
