To connect to a ZeroTier virtual network as a VPN from your phone or tablet, follow these steps:

1. Download and Install ZeroTier One:

   • Visit the Google Play Store on your Android device and search for "ZeroTier One."
   • Download and install the app.

2. Join a ZeroTier Network:

   • Open the ZeroTier One app on your device.
   • You will be prompted to enter a Network ID. This ID is provided by the network administrator or can be created if you are setting up your own network.
   • Enter the Network ID and tap "Join Network."

3. Authorize the Connection:

   • After joining the network, the app will request permission to set up a VPN connection. Tap "OK" to authorize.
   • You may also need to grant additional permissions such as location access, which is required for ZeroTier to function properly.

4. Verify Connection:

   • Once connected, you should see the network status change to "OK" within the app, indicating a successful connection.
   • You can now use the ZeroTier virtual network as a VPN on your device.

5. Using ZeroTier:

   • ZeroTier creates a peer-to-peer virtual Ethernet network, allowing seamless connectivity across different locations and devices.
   • It's an excellent solution for faster alternatives to traditional VPNs, multi-site cloud networking, remote team collaboration, and IoT applications.
