Home 5G and fixed-wireless plans from Verizon (69%) and T-Mobile Home Internet (65%) report coverage of San Antonio homes (Verizon’s figure combines Fios fiber and 5G Home).

About 12.1% of San Antonio households, roughly 67,100 homes, get online only through a cell plan. For them a mobile outage is an internet outage.
Fiber networks in San Antonio
Besides the statewide providers, San Antonio has fiber service that most cities do not:
- Google Fiber. Google Fiber sells fiber internet in parts of San Antonio. Its service status and outage notices are in the Google Fiber app and at fiber.google.com, and it does not share equipment with the cable or phone company.
A fiber network runs on separate lines, so an outage on one provider in San Antonio does not mean the others are down.
Power and weather behind internet outages in San Antonio
CPS Energy customers averaged 74 minutes without power in 2024, across 1.15 interruptions each, against 1,271 minutes for Texas as a whole. Cable nodes and fiber cabinets run on batteries that last hours, not days, so a long power cut can take internet down even for homes whose own power has returned. See San Antonio power outages when both go out together.
Bexar County logged 677 storm reports since 2015, most often hail, flash flood, and thunderstorm wind. Reports peak in April. Power outages were named in 1 of those storm episodes. Wind, ice and flooding damage poles and buried lines, which is how a storm turns into an internet outage as well as a power outage.
Fiber reports reach 71.7% of San Antonio homes, cable 93.5% and copper lines 29.1%. Where fiber runs to the home, a red or blinking LOS light on the optical terminal points to a line problem that a restart will not fix.
