C Spire's four highlighted plans start with a $50-a-month package offering 500 minutes of talk time and unlimited SMS and data, and a $70-a-month plan, which offers unlimited talk in addition to SMS messaging and data. While these two plans place limits on audio and video streaming, a C Spire spokesman told that streaming is free to iPhone subscribers for those plans through the end of the year; in 2012, the $50- and $70-per-month plans will get 30 minutes of free streaming, followed by additional charges (according to , $5 for 2 hours, $10 for 5 hours, and $30 for unlimited monthly streaming).

C Spire's higher-tier plans include a $90-a-month offering with 1000 minutes of talk time and a $100-a-month unlimited talk plan. These plans include unlimited SMS and data, with no limitations on streaming.

All service plans require a two-year commitment to C Spire.
