Hi Chris,
I realize your iPhone is crippled, but on Android we can see nearby towers.

And on Android, it's literally trivial to set the bands we wish to use.
It's a hidden activity, but anyone who knows Android knows how to find it.
And on Android (not iOS) we can see exactly what band & unique sector
antenna we're connected to and we can also see nearby neighboring cells.

While you can't do that on the crippled iPhone, even you can use the web.

So it's definitely possible.
But we all would likely agree choosing your tower by band is inefficient.
The question is only whether or not we are intelligent enough to figure out
how to do it more directly - e.g., by blacklisting/whitelisting tower IDs.

Again, I realize you hate that the iPhone is crippled, but on Android we
can easily set EARFCN so "hopping between towers" is certainly possible.
What we want though is a more direct way, e.g., blacklisting PCI or CellID.

Again, you're thinking like crippled iPhone users & not like Android users.
We're empowered to see all neighboring towers & bands they support.

If you stop thinking like crippled iPhone users, you would be able to help.

I'm not sure what you're insinuating, as usually you complain whenever
something is on Android you can't do on iOS (which is a lot of things).
Suffice to say that there are plenty of T-Mobile USA plans that limit the
amount of hotspotting you can do, and, in fact, they likely limit it on
purpose because they also want to sell you a mifi device for home Internet.
"Q: Can a hotspot replace home internet?
A: Hotspot devices, mobile hotspots, and their plans were made
for limited high-speed data usage on the go. These are not intended
to replace your home internet."

If you look at T-Mobile's plans on public resources, you'd see all sorts of
prices and limitations on hotspotting for both tablets and for cellphones.

Well, I have never approached even 1GB of hotspot/tethering data myself.
But it's a worthwhile endeavor to be able to choose the tower at will.
This thread has shown that it's definitely possible to see all the nearby
tower sector antennas & the bands that they support (at least on Android).
Given it's trivial to set the bands on Android, your argument that setting
the bands manually is "so tortuous to do that it's not worthwhile" may be
the case (even on Android, & certainly the crippled iPhone couldn't do it).
But I'm not on the crippled iPhone (although I do have plenty of iPads).
So I'll continue to seek a way to manually connect to unique celltower IDs.
