Just received 3 consecutive calls on cell - no message.  What is interesting is I activated a new phone on Friday (upgraded current phone, so same number) and about starting the following day I started receiving a number of calls from various numbers all over the US.  In the past 4 days I received over 25 calls...this also happened 2 years ago when I upgraded my phone which leads me to believe either AT&T or Samsung is selling phone numbers of recent phone activations.  I have also been inundated with text and e-mail spam from both since the moment of activation.
