Schertz Internet Guide — Compare Speeds & Prices

Schertz is a fast-growing city of roughly 44,000 residents in Guadalupe County, situated along the I-35 corridor northeast of San Antonio. The city borders JBSA-Randolph (Joint Base San Antonio–Randolph), and a significant portion of residents are active-duty military, veterans, and defense-sector professionals who depend on reliable home internet for remote work, video calls, and family streaming.

The Schertz broadband market is served primarily by three providers. Spectrum offers cable internet with the widest residential footprint in the city, covering most neighborhoods from FM 78 to FM 1518. AT&T provides DSL and limited fiber service in select Schertz subdivisions — fiber availability varies block by block, so address-level checking is essential. T-Mobile 5G Home Internet has expanded aggressively into the northeast San Antonio metro, and Schertz residents near the I-35 corridor and FM 3009 typically see strong 5G signal strength.

Unlike central San Antonio, Schertz does not have Google Fiber or Grande/Astound coverage. This means Spectrum is the dominant wired broadband option for most households, with T-Mobile providing the primary wireless alternative.

Schertz's proximity to JBSA-Randolph means many residents are military families with specific internet needs. Frequent PCS moves make no-contract options especially valuable — both Spectrum and T-Mobile offer month-to-month service with no early termination fees. AT&T also waives early termination for active-duty military with PCS orders.

For families where one spouse is deployed and relies on video calls to stay connected, upload speed and latency matter more than raw download speed. AT&T Fiber (where available) excels here with symmetrical upload speeds. Spectrum's 35 Mbps upload is functional for a single video call but can struggle if multiple family members are on video simultaneously.

VPN usage is common among DoD employees working remotely from Schertz. Fiber and cable connections handle VPN overhead without noticeable performance loss. T-Mobile 5G Home Internet works with most VPNs but may experience occasional latency spikes that disrupt sensitive applications.

Military families should also check for provider-specific military discounts. T-Mobile offers a $10/month discount on home internet for military and veteran customers, bringing the price to $40/month. AT&T offers up to 25% off for active-duty and veteran households on qualifying plans.

For most Schertz households, we recommend checking providers in this order:

1. **AT&T Fiber** — If available at your address, this is the best option. Symmetrical speeds, no data caps, and competitive pricing from $55/month. Check address availability first, as coverage is limited to select subdivisions.

2. **Spectrum 300 or 500 Mbps** — The most widely available wired option in Schertz. No data caps, no contracts, reliable cable performance. The 300 Mbps plan at $30/month is the best value for budget-conscious households. Upgrade to 500 Mbps ($50/month) if you have 4+ simultaneous users.

3. **T-Mobile 5G Home Internet** — Best for households that want simplicity, no contracts, and competitive pricing at $50/month. Military families get it for $40/month. Ideal if Spectrum is your only wired option and you want an alternative.

Avoid AT&T DSL in Schertz unless it is genuinely your only option — speeds are too slow for modern household demands. If you are in a newer Schertz subdivision and have AT&T Fiber access, take it. Otherwise, Spectrum cable is your most reliable wired choice.
