I bought my Moto X directly from Motorola for use on Sprint. It was my understanding that doing so would give me an unlocked phone. I activated it locally about this time last year on a new Sprint account . Now I'll be spending several weeks in Europe and would like to just use a pay-as-you-go plan while there. Shouldn't my phone already be unlocked for use on any GSM or CDMA carrier world wide by just putting in their SIM?
