In case you haven’t noticed, T-Mobile really likes to antagonize AT& T. Only hours after AT& T announced its upcoming NumberSync service, T-Mobile let everyone know that it too is working on such a system. Apparently T-Mobile’s will be better, not that either of them exist yet for us to verify that.


With AT& T, NumberSync will let you share the same account information across multiple SIM cards. So you might have an LTE-equipped watch that run on the same plan as your phone. T-Mobile’s system will presumably offer similar functionality, but Tmo doesn’t have shared data plans currently. So, there’s potentially a bigger benefit to sharing a single number than there is on AT& T, which already uses shared data.


T-Mobile’s Mike Sievert came out swinging saying, “What we are working on will make this version one offering from AT& T look small. Our strategy is to ask customers what they want and need, and then build it. AT& T’s is to build or buy things, and then try to convince customers they asked for it. ”


Sick burn. dude. That’s all the information we’ve got about the service… so basically none. It’s happening and T-Mobile says it’s going to be way better than NumberSync. We’ll see about that once they’re both available.
