How to make phone calls anywhere with Roam
No mobile reception? No problem. Making phone calls in areas without mobile coverage has long been a challenge — and it's the original problem Roam was built to solve.
What is Roam?
Roam is a portable, long-range WiFi unit that connects to both WiFi HaLow and standard WiFi networks, then creates a local hotspot your devices — including your phone — can connect to. It's battery-powered, waterproof, and designed to go wherever you go.
For full technical specifications, see the Roam product documentation.
Setting up your Roam unit
To configure your Roam unit, download the TX-E Connect app from the Google Play Store or the Apple App Store.
With the app, you can connect to your Roam unit via Bluetooth (make sure your unit is powered on first). From there you can:
Scan for and connect to WiFi networks — both long-range (WiFi HaLow) and standard WiFi
Save multiple networks so Roam connects automatically
Set up your hotspot name and password — so your phone and other devices can join
Enabling calls and texts
Once your phone is connected to the Roam hotspot, turn on WiFi Calling in your phone's settings. This enables:
Regular phone calls and SMS texts
Emergency calls — including AML (Advanced Mobile Location), which automatically sends your GPS location to emergency services when you call 000. This is especially important in regional and remote areas where mobile coverage is absent. See our article on emergency communication and property safety for more on how this works in practice.
With WiFi Calling active, your phone works just like it would on a normal mobile network — even where there's no coverage at all.
