Use: sticky per crew kickoff. All agents in one crew usually work one job, so they can share one session id; if two agents must look like two visitors, build two tools with two ids.
Sticky pins the device for that session id, not the exit IP - mobile carriers re-NAT on their own schedule, so a pinned modem can still surface a new address. Without a -sid-, sticky and auto modes do nothing across connections. Unknown tokens are dropped silently, so -session- is not a substitute for -sid-.
