You don't enter the imei # you enter the # on the SIM Card which could be why it isn't working, plus you have to update the carrier settings of the iPhone through iTunes.

After you've entered the SIM Card # in self serve and it's active you can simply take it from one phone to another if the SIM Card size is the same from phone to phone.
