5G in China now has about 100 million subscribers but the results in the West have been dismal. T-Mobile is bringing lower-priced phones to the U.S. while upgrading ~3,000 towers per month. On the lightly loaded network, speeds average over 300 Mbps. A promotion drives the cost down to $200.
1/3rd of the U.S. will be covered with mid-band 5G yearend, and They won't stop. TMO has passed AT&T to become #2 in the U.S. and is going after Verizon. For at least a year and possibly two or three, TMO will have a much better network.
Both Verizon and AT&T have been cutting capex and praying consumers won't care that most of their "5G" is slower than decent 4G. Verizon's mmWave Ultra is the fastest network in the world, but 5G customers connect to it less than 1% of the time.
