That’s a feature when you have an iPhone with 2 active cellular plans (Dual Sim is available on iPhone XR, XS, 11, 12, 13, 14 and SE 3.)
The way iPhone handles Dual Sim does not allow Data to be active on both plans at the same time (that means the iPhone uses can receive and send calls on both sims all the time but uses the data plan of only one, even if the second one has better reception).
The feature OP asks about, allows iPhone to switch to the second data line if the first one fails due to bad coverage.

Great explanation — just to add FWIW, the second-gen SE supports it, too.
