Setup guide
Set up LineFerry in six steps.
Answer a question, tick a box, move on. Your progress is saved on this device, so you can stop and come back.
Step 1 of 6
Which Android phone will hold your SIM?
This phone becomes the gateway. It stays at home (or in your bag), keeps your SIM, and passes calls to your iPhone.
Good news. This is the phone LineFerry is built and tested on. Carry on.
Very likely to work. It's the same hardware family as the certified S10+, but we haven't tested it yet. You're welcome to try; tell us how it goes.
Not yet. Support is planned but not ready. Join the waitlist with your model and we'll tell you when it works.
Not supported yet. Each phone model needs work on our side. Join the waitlist and tell us your model; requests decide what we certify next.
Step 2 of 6
Is it rooted with Magisk?
The gateway needs root to handle calls on the SIM. Not sure? Look for the Magisk app and open it. If it shows a version number next to Installed, you're rooted.
Rooting comes first. It means unlocking the bootloader and installing Magisk. It wipes the phone, may affect its warranty, and some banking apps stop working on it, which is one reason to use a spare phone as the gateway. Follow a guide written for your exact model, then come back here.
Step 3 of 6
Install the gateway module.
One file, installed through Magisk. Your early-access invite has the download link.
It says Gateway Stopped? See the gateway won't start.
Step 4 of 6
Install LineFerry on your iPhone.
During early access it comes through Apple's TestFlight. You need iOS 17 or later.
- Microphone
- so the caller can hear you
- Local network
- to find and talk to the gateway
- Notifications
- for texts and missed calls
- Contacts
- to show names instead of numbers (optional)
Step 5 of 6
Pair them with one scan.
Both phones on the same Wi-Fi, or the iPhone on the gateway's hotspot.
No camera handy? Auto-Detect Gateway in the same tab finds it on your network.
Step 6 of 6
Ring yourself.
From any other phone, call the number of the SIM in your gateway.
Your number now rings on your iPhone.
Worth a read next: how networks affect ringing, especially if you'll use the gateway's hotspot outside.
