AT&T vs Xfinity in Mobile
Mobile shoppers trade AT&T’s faster fiber uploads and lower starting price against Xfinity’s strong cable option where available.
Xfinity is the better overall pick in Mobile because its cable network offers a strong balance of availability and download speed, despite AT&T’s better upload speeds and lower starting price. AT&T wins on speed, coverage, and price: its fiber reaches about 59% of the city at up to 5,000/5,000 Mbps, while Xfinity reaches about 11% at up to 2,000/300 Mbps. Xfinity is right for households wanting a solid cable option where available; AT&T suits fiber-eligible homes, heavy uploaders, and budget-focused shoppers. Check your address before choosing.

Rank score (0–100) is each provider’s Speed Score, discounted for weak upload, times the share of that ZIP it reaches — the same rule that orders providers on the Mobile city page, so it moves as availability changes street to street.
