This is a US problem but Americans don't travel enough to understand.
In the US I get shitty coverage and frequent tower handoffs to lower bandwidth signals. In a downtown capital city, I generally get 30Mbps to maybe 100Mbps outside on a clear day.
Contrast that with where I usually am, using actual good technology and true 5G, I get fibre-like pings with 1Gbps all the time, even inside buildings. If I'm outside near a tower like in the US, I get 2Gbps nearly symmetrically. Constant excellent signal, no disconnects, no dead zones.
It's just sad how easily the American populace is duped. Even the article mentions how there were continuous lies and the actual rollout to 5G will take many many years. The rest of the world has already done it. Heck, even Korea has announced 6G consumer installations in the next 5 years. And if you're by the Samsung Campus with a demo tech, you can use it now!
