Pre-paid phone - who is my carrier?

Factual Questions
1

My son recently found his old pre-paid phone. It disappeared into one of those black holes that sometimes appear in teenaged boys’ rooms. Now that it is back, I would like to buy some minutes for him… but no one can remember what service this phone uses. And poking around I can’t find anything in or on the phone itself. I have a phone number, a serial number, and a SIM number but nothing else. I tried to use net10 thinking that might work… but no dice.

So is there a lookup service, where I can figure out who this phone is through? Or is there some other way to turn this thing back on?

Thank you. That did the trick.

Did you check with the carrier? After I posted that I was remembering that carriers re-assign phone numbers if they are not used within a certain period of time.
