A device that ships directly into a no-cellular zone will be unable to send via satellite until it has found cellular (or WiFi) coverage at least once. Pre-provisioning during QA on a cellular-capable bench is the standard mitigation. -**Satellite payload budget.** The Notecard for Skylo bundle includes 10 KB of Skylo satellite data, and the Skylo NTN link enforces a hard 256-byte maximum per Note. The compact alert template is well under that ceiling; frequent triggering in a no-cellular environment will consume the bundle faster.

A severe I²C lockup (e.g., a partially-completed transaction interrupted by a reset) could block all communication. A production design should include bus-error recovery and a hardware watchdog.
