These are the six networks that file service in the most San Bernardino ZIP codes, drawn from 14 residential providers on record. Satellite is left out because it reaches every address.
| Provider | Technology | ZIPs served (of 6) | Top filed speed |
|---|---|---|---|
| Frontier Fiber | Fiber | 6 | 7 Gbps |
| Spectrum | Cable + Fiber | 6 | 1 Gbps |

| AT&T Internet Air | 5G Home | 6 | 100 Mbps |
| T-Mobile Home Internet | 5G Home | 6 | 100 Mbps |

5G home coverage is ZIP-wide here: Verizon 5G Home, AT&T Internet Air, and T-Mobile Home Internet all file in every one of the six ZIP codes, at filed speeds from 100 Mbps (AT&T Internet Air) to 1 Gbps (Verizon 5G Home). Satellite (Starlink, Viasat, HughesNet) isn’t ranked because it covers every San Bernardino address.
Frontier Fiber and Spectrum each file wired service in every San Bernardino ZIP code, so no ZIP code here depends on a single wired network on paper. Above the gigabit line, San Bernardino has Frontier Fiber (7 Gbps) and AT&T Fiber (5 Gbps). Frontier Fiber carries the table’s top speed, 7 Gbps, and no wired network reaches more San Bernardino ZIP codes.
