T-Mobile and Sprint want to let you share a number across devices too
Unsurprisingly, T-Mobile started off by taking a shot at AT&T's NumberSync service. T-Mobile COO Mike Sievert said:
T-Mobile didn't give much more info on the plans, but the end result should be to allow users to share one phone number across devices and SIM cards.
Of course, Sprint didn't want to be left out either, and told Re/code that it is also "exploring offering a service that would allow a customer’s smartphone, tablet and other devices to share a single phone number."
No one has details right now, but we should find out more soon enough.
