How Rightier works
A local Edge, your local SIM, and your app.
That’s all you need to make and receive local calls,
even while abroad.
The principle: linking Internet and the local mobile network
Rightier lets you use your local SIM from anywhere in the world. Your app connects to a Rightier Edge device placed in the country of your choice. The Edge uses your SIM to make and receive local calls.
Result: your calls become local calls, even if you are thousands of kilometers away. Your recipient receives a classic local GSM call — no app, no Internet, no change of habits.
Overview of how it works
Rightier connects your app to your local SIM placed in an Edge.
You make and receive local calls as if you were physically in the country.
Rightier vs WhatsApp
WhatsApp only works if both people have Internet and use the app. If your recipient has no Internet, is in a rural area, uses a basic phone or does not have WhatsApp, the call becomes impossible.
Internet calls may be subject to network restrictions, making VoIP unstable or sometimes unavailable. Rightier uses your local SIM installed in the target country. Your recipient receives a classic local GSM call, without Internet, without an app, without a smartphone. This is why Rightier works everywhere, even where Internet calls fail.
What Rightier is NOT
Rightier uses your own SIM, in the country of your choice.
You keep full control of your local number.
