I'm not able to get 5G connections in (or around) San Francisco with my Pixel 4a (5G) despite the T-Mobile coverage map claiming 5G coverage.
My Team of Experts told me to get an R15 SIM, so I did, but it did not help.
My Team of Experts then told me the nearest 5G tower wasn't actually close, so I drove to the tower, but still no 5G.
Has anyone been able to get a 5G connection in San Francisco?

Alas, Band 2 is 4G LTE, not 5G

UPDATE:
T-Mobile called me in response my FCC Complaint, and promised to get back to me with accurate 5G information for San Francisco.
