Performance & Coverage: The SIM card delivers on its promise of 4G and 5G connectivity across major U.S. carriers (Verizon, T-Mobile, AT&T, US Cellular). Users report reliable speeds, though signal strength varies by location—some note weaker reception (2 bars vs. competitors' 3-4).

Ease of Use: Plug-and-play activation with online management is a plus. However, auto-selection of networks (vs. manual) and unclear registration steps (e.g., ambiguous "number" field) caused minor confusion.

Data Value: At 6GB/90 days, it suits low-data devices (security cameras) but drains quickly for heavy use (e.g., speed tests). Refills are flexible but cost-per-GB is high for power users.

U.S.-Only Routing: Confirmed by most users to reduce latency, though one reviewer couldn’t verify independently.

Caveats: No voice/SMS support. Customer service issues reported (bounced emails), and some Spanish-speaking users desired larger data packages.

Verdict: Ideal for intermittent IoT use; less practical for sustained high-data needs. ★★★★☆ for reliability, minus one star for opaque support and data limits.
