What does unlimited mean?

Total: one allowance for the validity period. Daily: an allowance each day, continuation after use unconfirmed. Reduced speed: stays connected at a lower speed after the high-speed allowance. No throttling: explicitly no usage-based speed reduction. Fixed speed: a speed cap from the start. Policy unavailable: unlimited data confirmed, speed rules unknown. No throttling does not guarantee network speed.
