AT&T moved to its four-tier "Simple" fiber lineup on 7 June 2026 (300, 500, 1 GIG, 5 GIG); the 100 Mbps and 2 GIG tiers were retired. Prices shown include the $10/mo autopay and paperless-bill discount with a bank account or debit card (credit card is $5/mo more). Bundling an eligible AT&T wireless plan takes 20% off each month. The 5 GIG plan requires an XGS-PON ONT installed during setup; professional install is typically free with new service.
Honest Analysis
Where Spectrum wins

- +No data caps on any plan
- +No installation required for existing customers
- +Can use your own modem (saves $5-10/mo)
- +No promo rate that expires (listed price is ongoing)
Where AT&T Fiber wins
- +Symmetric upload speeds at every tier
- +Better peak-hour consistency (dedicated fiber vs shared coax)

Symmetric 300 Mbps up vs Spectrum's 20 Mbps up. For a solo remote worker, AT&T at $50/mo matches Spectrum's entry-tier price with vastly superior upload.
The upload math is decisive. AT&T 1 Gig gives 1 Gbps up. Spectrum Gig gives 35 Mbps up. Two video calls plus cloud backup will saturate Spectrum's upload. AT&T handles it comfortably.
Fiber's 8-12ms latency vs Spectrum cable's 18-25ms. Plus Spectrum peak-hour congestion causes lag spikes that fiber avoids.
At $50/mo with no data caps and adequate download for streaming, Spectrum is a perfectly reasonable choice for light users who do not need upload speed.
