We do not publish speeds or prices here. Both providers change them constantly and by market, and a stale number is worse than no number. Coverage is the part that is federally reported and verifiable.

Where you can get both

Metro areas where both Fidium Fiber and Xfinity report service, ranked by how well covered the less available of the two is because that is what decides whether you genuinely get a choice.

These percentages count each operator's whole reported network. 63.3% of what Fidium Fiber files with the FCC is fiber. The FCC publishes that split nationally and never per metro, so a high number here means the operator reaches the metro, not that it reaches it on that technology.

Which should you pick?

Honestly, in most of the places above only one of them will actually reach your building, and that settles it. Where both do reach you, the useful question is the technology rather than the brand.

That is the case here: Fidium Fiber is mainly fiber and Xfinity is mainly cable. The practical difference is upload speed and consistency rather than headline download speed, we explain what that means here.
