Install the gateway

Before you start, the phone must be rooted with Magisk and have your SIM in it. See What you need.

1. Get the module

Your early-access invite includes a download link for LineFerry-Gateway.zip. Download it on the gateway phone.

2. Install it in Magisk

1. Open Magisk.
2. Go to Modules and tap Install from storage.
3. Choose LineFerry-Gateway.zip.
4. When it finishes, tap Reboot.

The module installs three things: the LineFerry app you’ll use, a background service that does the call handling, and the audio support for your phone’s chip. It also sets the gateway as the phone’s call handler, which is how it can pass calls to your iPhone.

3. Start it

After the reboot, open LineFerry on the gateway and tap Start Gateway. The status should read Gateway Active.

From then on the gateway starts by itself after every reboot, and restarts itself within seconds if anything goes wrong.

Stopping the gateway

Tap Stop Gateway in the LineFerry app. The phone goes back to behaving like a normal phone: calls ring on it, with its usual dialer. Tap Start Gateway to hand calls back to your iPhone.

Removing it

In Magisk, go to Modules, remove LineFerry, and reboot. The phone returns to its normal dialer.
