Does Quantum Fiber have equal upload and download speeds?
All plans include equal upload and download speeds except for 2 Gig (but upload speeds still beat cable in most areas!). Quantum Fiber’s ultra-fast symmetrical speeds make your internet experience fast and smooth, especially for video calls, intensive gaming, and sharing or backing up large files.
Limited availability. Service and speed in select locations only.
Does Quantum Fiber Internet require annual contracts?
No. With Quantum Fiber, you always have the freedom to make the best choice for your home and budget, and you won’t owe cancellation fees if you have to make a change.
Do I have to bundle to get the best price on Quantum Fiber?
No. Quantum Fiber provides internet at the same great rates for all customers, and you’ll never see promotional or “introductory” prices that suddenly increase in year two.
If you do like a deal, you’re in luck. For a limited time only, you can pair Quantum Fiber with AT&T Wireless to save $40/month on your phone bill for the first 12 months! After that, you’ll continue saving with the $20/month offer available to all Quantum Fiber customers.
