Android Phone Configuration for SIM & Proxy

I need an experienced professional to create a custom script for my Android phone. The script will configure the phone to switch SIM cards, change locations, and use a SOCKS proxy. This setup should allow all apps to reload through the proxy.

Key requirements:
- Custom script creation for Android
- SOCKS proxy configuration
- SIM card and location switching

The script should provide both automatic and manual options for changing the SIM and the location. It should also be able to switch between these two modes at will. Ideally, the freelancer should have extensive experience with Android configurations and a deep understanding of network proxies. Please include any relevant past projects in your proposal.
