Google / Motorola Afterthought
People have been saying Apple is the only company capable of forcing wireless carriers (MNOs) to decouple phones (terminals) and phone numbers from network access contracts. The truth is now Google is the other one. Commanding a huge user base, owning the Android OS, the Google Voice service, and now owning a mobile hardware division, Google definitely is in a position to release a decoupled device, with multiple physical, or even a virtualized SIM card slots. It would have a phone number associated with the Google account (not with a SIM card). And would use any network to complete calls.
I have a feeling the GSMA is today, where the record labels were, when the first iPod was released and MP3 took the world by storm. SIM cards in 2011 are, where CDs were in 2001. Obsolete products of the old era.
