nope. this is far worse than you think. the average cell tower is about 2-3 miles from you. this one bolted to something that will fall back to the atmosphere in 5 years will be about 200-300km from you. the service here is not starlink with mmWave - this is plain old cell service.
that means the signal level will be far fainter, so the achieveable bitrate will be minuscule compared to the terrestrial service.
there's nothing special about this, it's the very same cell service, the same frequency bands, same bandwidth, same everything. but it has to cover a far larger area: remember the entire starlink constellation will consist of 40k satellites (if they ever manage to have that much in orbit) that supposedly cover the entire world. tiny countries in europe have about 6-10k cell towers each, so the best thing you can expect from is texting. even voice calls are challenging. this is not mobile broadband.
