T-Mobile CEO rules out letting SpaceX's Starlink Mobile run on its network

That doesn't mean the two companies can't do business together. According to Gopalan, SpaceX being a T-Mobile customer, or the other way around, would simply be a commercial agreement. He also said he's "very happy to look at a resale arrangement" for a complementary product, which is how the carrier already handles satellite withT-Satellite, "but an MVNO is a wholly different thing".
