I have a Nokia 6020 prepaid with Movistar Spain. Because I lost my number - Movistar changed the rules and i did not buy new credit soon enough -, i tried to get an unlock code from Movistar. However they did not react to my emails. The IMEI of the phone is: 354532016087086 The provider is Movistar (I dont know if it is 21402 or 21407) in Spain.
