We set some huge goals in 2020 that some thought were impossible, but we smashed them. Today, T-Mobile’s high speed Ultra Capacity 5G covers over 50 times more people than Verizon and it’s growing. We continue to demonstrate that we are way ahead of the competition on 5G and poised to become the country’s overall network leader.
