EarthLink

Plans start at $39.95/mo for 300 Mbps up to 5 Gbps with symmetric speeds, typically on a 12-month price lock. Because it rides AT&T's lines, it's available at the same San Jose addresses where AT&T has built fiber — so the real question is whether fiber has reached your street. Call (888) 224-5870 and we'll run both quotes at your San Jose address.

Verizon 5G Home Internet
Verizon 5G Home Internet reaches an estimated 66% of San Jose. It runs on Verizon's 5G network with a self-install gateway, a flat $50/mo, no contract, and no data cap. Strong ultra-wideband signal can push speeds toward 1 Gbps, though coverage varies block to block. Since T-Mobile competes for the same households, the right pick comes down to which carrier is stronger at your address. Call (888) 224-5870 and we'll check both at your San Jose address.
