Most of those sats don't support direct to cell though. But more will come of course.

And are the spot beams for direct to cell the same in size and quantity?

Good question. I could not find the cell size specifically for the LTE coverage, and agree it will take time for the constellation to turn over to maximize the direct to phone capability. Regardless, SpaceX launches more StarLink satellites in three flights (~69) than Iridium has in its entire constellation.
