"Everyone" Buying 5G As Samsung 5G Falls to $129
5G phones have taken over. >70% of phones sold in China, Korea, Australia, Canada, and the United States are now 5G. I believe Japan, England, and most of Western Europe are similar but I don't have firm data.
5G still does nothing important, of course, but the cost difference between 4G & 5G is very small. The immensely popular Apple 13 doesn't even have a 4G model.
Since December 2019, I've been reporting that prices of $150-220 were driving demand for 5G phones. Boost Mobile, owned by Dish, on November 7 2021 dropped the price of the Samsung A32 5G to $129.
Ed Walter beamed with pride as he told us AT&T's next 15 million lines of fiber will offer 10 gigabits upstream and down. This is the first large 10 Gbps symmetric build in the world. 
December 2021: Verizon is just now starting to sell many fixed wireless connections. 8 million in 2023 is unlikely because it did not build the planned 30 million homes of mmWave. Latest data is that Verizon cell site radius is < 200 meters rather than the 600 meters it thought was practical in 2018. A $10-20 billion mistake. As mid-band reaches half the country *late 2022 or 2023,) Verizon could take millions of customers from cable if it priced at $30-45. Mid-band will have so much excess capacity that would be a highly profitable offering. The marginal cost of a customer added to the network even with a high cap will be < $10/month.
December 2021 Since 2017, every telecom reporter on the planet has written about "Gigabit LTE," a theoretical peak that is more often 150-350 Mbps down. 5G NR adds very little. The gain in theory could be 15-50%, but in practice 5G in frequencies below 2100 MHz is often slower than 4G. The apparent improvements, from 4G 50-150 Mbps download to 5G 100-450 Mbps are because of more spectrum (mid-band) and more MIMO antennas. Both are 4G tech shipping since 2017.
Update December 2021: Vestberg was dead wrong about a $200-400/cost per home passed for mmWave. The word from Verizon in 2017 was to expect 600 meter reach for mmWave. Testing by Earl Lum found Verizon built to a 200 meter radius. The economics of mmWave deteriorated because the capability was massively overestimated.
Michael Weening, to my amazement, has delivered for Calix's modestly sized customers a marketing program with the sophistication I would expect from a giant company. In some ways, the Calix suite is even better than Verizon's.
