San Jose residents often have real fiber choice. AT&T Fiber and Frontier both offer symmetrical multi-gig service, with Frontier the budget leader at $29.99; Sonic is the local speed champion (up to 8–10 Gig) but availability depends on location; and Xfinity's cable reaches the most homes. Many AT&T customers add AT&T Wireless for a bundle discount.
