Without Contact, the device goes online directly through the carrier or the current Wi‑Fi. After you turn it on, data first travels on a protected path to the Contact network and only then is sent to the website or service.
Three stages that happen on their own
- The app creates a secure connection.
- The device sends data through that connection.
- Contact chooses an available path and keeps the link working.
You do not need to choose a server, port, or “best route”. Add the link once and tap connect. If Wi‑Fi drops or the phone switches to a mobile network, the connection restores without new setup.
What stays on your side
The link from the account is your access. Do not publish it or send it to people you do not know. The number of devices online at once is set by the plan: from three to seven. The same link works for both a phone and a computer.
