Rightier Edge
The bridge between your local SIM and your application.
Incoming calls, outgoing calls and SMS at local rates, wherever you are.
Why Rightier Edge?
Rightier Edge turns your local SIM into a number accessible from anywhere in the world. You make calls, receive calls and receive local SMS, even while abroad, without roaming and without extra fees.
A local SIM costs less than €1 (no subscription) in most countries. You get a full local number with no commitment and no recurring cost.
Unlike classic VoIP solutions, Rightier uses your local mobile network (GSM). This ensures total reliability, even in countries where Internet calls may be limited or filtered. Your recipient receives a classic local GSM call — no app, no Internet, no change of habits.

Comparison: Edge vs Roaming vs VoIP
Rightier Edge
Local calls & SMS, GSM reliability, no extra fees.
Roaming
€0.50 to €2.00 / min, depends on operator agreements.
Classic VoIP
Internet calls, low answer rate, requires an app.
Rightier Edge 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 Edge 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.
