Hardware Chassis vs Virtual Device Services

**Virtual device services** rent mobile instances on shared remote infrastructure. Useful for short pilots without shipping hardware. **Phone farm box hardware** is tangible equipment — chassis, wiring, PSU, cooling, and hub — you rack, power, and maintain locally. Suitable when you need BOM, packing photos, warranty terms, and long-running batch control on owned gear. **When to choose phone farm box:** - Multi-account workflows on physical devices you control - App QA requiring real sensors and radios on hardware you own - Long-term operations with export packing and datasheet requirements - Teams needing custom rack layout, hub tier, and cooling plan **When virtual services may suffice:** - Quick prototyping with low hardware logistics tolerance - Temporary campaigns under ~30 days Phones Farm Box supplies hardware and remote setup services from Guangzhou — not virtual device subscriptions.
