About this app

ON by SIMO keeps you online the moment your primary network can’t. When your main carrier loses signal, ON automatically takes over—so you stay connected at home, on the go, or anywhere in the world.

Works seamlessly across 100+ countries/regions, with 200 MB of free data every month to get you started. Need more? Upgrade anytime with flexible data plans. And with data rollover for up to 11 months, nothing goes to waste.

ON is your always-ready backup connection. Set it up once, and it’s there whenever you need it—no manual switching, no interruptions.
Your everyday connectivity backup. Stay connected when Wi-Fi or cellular fails.
