STI vs T-Mobile Home Internet

What T-Mobile Actually Delivers in South Texas

T-Mobile advertises typical speeds of 133–498 Mbps nationally. In rural South Texas — Medina, Atascosa, Frio, and surrounding counties — customers typically see download speeds of 87–200 Mbps, rarely higher, and upload speeds of 12–15 Mbps. Performance also fluctuates based on time of day, how many T-Mobile phone users are on the same tower, and distance from the nearest cell site.

STI's Velocity 400 delivers 400 Mbps down and 25 Mbps up. That's a dedicated fixed wireless connection — not a shared cellular signal — built specifically for the terrain and communities of South Texas.

The Rural Availability Problem

T-Mobile Home Internet requires a stronger, more concentrated 5G signal than regular phone service. You can have T-Mobile cell service at your address and still not qualify for home internet because the tower signal isn't dense enough for residential broadband. In our coverage area — Hondo, Castroville, Devine, Lytle, Dilley, Sabinal, and 30+ surrounding communities — T-Mobile Home Internet availability is limited and inconsistent. STI's Air Fiber was built specifically for these communities.

Shared Network vs. Dedicated Coverage

T-Mobile Home Internet shares the same 5G cellular network as every T-Mobile phone customer in the area. During high-traffic periods, home internet customers experience reduced speeds due to congestion and data deprioritization. STI's Air Fiber uses dedicated fixed wireless infrastructure — your connection isn't competing with every T-Mobile phone user on the local tower.

Where T-Mobile Wins

Where T-Mobile Home Internet is available and the signal is strong, it's a competitive product. Pricing starts as low as $35/month with AutoPay and a T-Mobile voice line. Self-install means no waiting for a technician. If T-Mobile's eligibility checker says yes at your address and you already have a T-Mobile voice plan, it's worth evaluating. But if it says no — STI is the purpose-built alternative for rural South Texas.
