T-Mobile Home Internet vs CenturyLink: Which Is Better?
A nationwide 5G gateway you plug in yourself versus a century-old copper phone network still delivering most of its internet the same way. Six rounds. Real numbers. One honest scorecard.
The verdict
T-Mobile Home Internet takes it, 6–0 on rounds.
This isn't a photo finish — a decade-old wireless product is outperforming a hundred-year-old wireline network on price, speed, and service almost everywhere both are sold.
Choose T-Mobile Home Internet if…
- • T-Mobile shows as eligible at your address and you want faster, more honestly priced internet
- • You're leaving DSL and want a real speed upgrade without a technician visit
Choose CenturyLink if…
- • You're in a rural pocket with no cell tower coverage and no fiber overlay nearby
- • CenturyLink's DSL is genuinely the only wired option at your address
