Usable mobile data
If a phone can reliably use cellular data in the exact area, an Eralion LTE PTT device may be a good fit.
Coverage Guide
Check coverage before you buy.
Eralion LTE PTT devices rely on supported network coverage. A quick check now helps you avoid a poor fit later.
Quick Decision
Can your phone use mobile data where you need the device?
This is the fastest first check. Building materials, congestion, carrier conditions, and local network quality can still affect performance.
No usable signal
If phones consistently have no usable cellular data in the area, Eralion LTE PTT devices are not recommended there.
Before You Buy
Good fit or poor fit?
Think about the exact areas where the devices will be used, not just the general city or building.
Good fit when coverage is available
- Road trips, events, and outdoor areas with usable coverage.
- Hotels, retail stores, and commercial buildings.
- Warehouses and logistics sites with usable cellular data.
- Security patrol routes and property management sites.
Not recommended
- Deep basements or tunnels with no usable signal.
- Remote or off-grid areas without cellular data.
- Locations where phones consistently show no service.
- Emergency-only communication when networks may be unavailable.
