5G is notoriously unreliable for me. Zero bars, one bar, three bars, bar to one bar. Then falls back to LTE. Back to 5G. Many dropped calls on my iPhone on T-Mobile. Garbled voice calls.
I have nothing good to say about T-Mobile and 5G...except it’s a LOT cheaper than Verizon.
I was shopping for a 5G backup for home internet service. No one offers it here despite being in an area known for its tech employers (occasional McLarens, Ferraris, and lots of Teslas spotted in the area).
