AT&T Goes Beyond Verizon's Current 2 Gig Maximum
Both cover the common 300 Mbps, 500 Mbps and approximately 1-Gig business categories. Verizon adds 2 Gig in limited areas. AT&T offers both 2 GIG and 5 GIG in select areas.
AT&T 5 GIG
AT&T states that the maximum wired speed to a single device on 5 GIG is approximately 4.7 Gbps. Actual speeds vary, and multi-gig hardware is required.
Verizon 2 Gig
Verizon advertises up to 2048 Mbps download and 2048 Mbps upload. Wired and wireless results can vary due to device, user and network factors.
Both Are Strong for Upload-Heavy Businesses
AT&T advertises equal upload and download speeds. Verizon's 300 and 500 plans are 300/300 and 500/500, its 2 Gig tier is 2048/2048, and its 1 Gig tier is listed at up to 940/880 Mbps.
Cloud backup
High upstream capacity reduces the bottleneck associated with sending large datasets to cloud storage.
Video meetings
Multiple simultaneous conferences benefit from substantial upstream headroom.
Large uploads
Media, engineering and data-heavy teams can benefit from fiber's strong outbound capacity.
AT&T and Verizon Have Very Different Fiber Footprints
AT&T currently advertises Business Fiber availability across parts of 39 states. Verizon's Fios Business availability page lists locations in Connecticut, Delaware, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Rhode Island and Virginia, plus Washington, D.C.
Neither figure means every address in those areas qualifies. Multi-gig tiers are more limited than the providers' overall fiber footprints.
No-Annual-Contract vs Term Pricing
AT&T
AT&T currently markets Business Fiber with no annual contract, no data caps and no additional Wi-Fi equipment fee.
Verizon
Verizon's displayed Fios Business prices currently use a two-year term that auto-renews. The page publishes different price-guarantee periods by tier.
Both Offer Business Mobile + Fiber Savings
AT&T publishes discounted Business Fiber pricing when bundled with eligible AT&T Business wireless service. Verizon currently advertises a $20 monthly credit when qualifying new Fios Business Internet is paired with an eligible Verizon Business smartphone plan, subject to offer conditions.
AT&T Includes Wireless Backup on Current 1 GIG+ Plans
AT&T's current 1 GIG, 2 GIG and 5 GIG plans include 5G internet backup with the required WNC-CGW452 gateway. AT&T says LTE may be used depending on signal, wireless coverage is not everywhere, and the backup does not operate during a premises power loss.
Verizon's current Fios Business plan table does not list built-in cellular backup as a standard inclusion. Verizon offers other connectivity products, but they should not be treated as automatically included with Fios.

AT&T Business Fiber may suit
- Businesses needing above 2 Gbps where available
- Teams preferring no annual contract
- Sites that value included 5G backup on 1 GIG+
- Eligible AT&T wireless customers seeking bundle savings
- Locations within AT&T's broader advertised fiber footprint
Verizon Fios Business may suit
- Fios-ready businesses in its regional footprint
- Teams needing symmetrical 300/300 or 500/500
- Sites that can use 2 Gig where available
- Buyers who value published price guarantees
- Eligible Verizon mobile customers using bundle savings
Verizon Fios vs AT&T Fiber for Business VoIP
Both provide far more bandwidth than ordinary hosted voice traffic requires. The practical benefits of fiber are strong upload capacity and substantial headroom when calls share the network with cloud apps, backups and video.
Latency
Low delay matters more to natural conversation than simply adding more gigabits.
Jitter & packet loss
Inconsistent packet delivery can hurt calls even when a speed test is fast.
Local network
Routers, switches and Wi-Fi still affect real call quality after the fiber enters the business.
What to Compare Before Ordering
Exact availability
Check the building, not just the city or state.
Equivalent tiers
Compare 300 vs 300 and 500 vs 500 before jumping to multi-gig plans.
Total price
Include Auto Pay, installation, activation, equipment, taxes and bundle conditions.
Contract flexibility
Compare AT&T's no-annual-contract structure with Verizon's displayed term pricing.
Upload needs
Both are strong upstream, but verify the exact plan specification.
Resilience
Evaluate backup internet and power separately from raw fiber speed.
