Having both T-Mobile and AT&T on one SIM has some advantages.

While AT&T has hands down better coverage than T-Mobile,
there are no doubt some places that T-Mobile has coverage that AT&T lacks.

AND, more importantly, I think, where both have coverage,
having a choice of provider for data will give some speed advantage to one or the other.
