There is one other difference between the two Pioneer plans offered in most areas. The difference is not only in the price but also in the billing increments. The plan offering the slightly lower price bills in 60 second increments while the slightly higher priced plan bills in a 6 second increment.
60 second increments bill up to the nearest minute after the call is completed. Example; you make a 2 minute and 6 second call, but you will be charged for 3 minutes.
6 second billing increments will save you an average of 12 to 14% compared to 60 second rounding. The same 2 minute and 6 second call will be billed as 2 minutes and 6 seconds. A plan that bills in 6 second increments will charge an 18 or 30 second minimum for the first minute.
Most customers find that each of the Pioneer plan works well because they end up saving so much money with either one!
