Satellite Network SIM Card
Budget: $250 – $750 USD
I need a custom SIM card for an Android handset that can bypass ground-based carriers and latch directly onto geostationary satellites. The core requirement is seamless 4G LTE data so every app—streaming, social, cloud backups—behaves exactly as it would on a terrestrial network. Voice and SMS are optional for later phases; for now the focus is unrestricted internet browsing with no usage caps and lifetime availability.
Here is how I see the engagement progressing:
• SIM architecture profile that negotiates with GEO satellites over 4G LTE bands.
• Firmware or authentication scheme that keeps the connection open indefinitely without relying on a traditional carrier IMSI.
• Complete schematic, security keys or provisioning files, and a step-by-step flashing/activation guide I can follow on a standard, unlocked Android device.
• Demonstrable proof of concept—lab video or remote test session—showing continuous data flow through a geostationary link.
Acceptance criteria
1. Android phone loads the SIM, registers on the satellite network, and receives a public IP.
2. Browsing, downloads, and app traffic run for at least 24 hours without throttling or paid top-ups.
3. All documentation lets a hardware partner scale this into small-batch production.
Experience with satellite telephony, LTE-M, or custom IMSI/TMSI programming will stand out. If you can bring the hardware as well as the protocol magic, I’m ready to start immediately and iterate quickly.
