The IAC-BOX offers both Flat Rate and Time Rate billing options.
Flat Rate:
A flat rate scheme gives guests access to the Internet for a limited amount of time (i.e. 6 days) and includes an allotted allowance of download limit. When the allotted amount of time (i.e. 6 days) has expired or the allotted download limit has exceeded, the guest loses connectivity to the Internet (similar to DSL) and a new Ticket must be purchased to regain access to the Internet.
Time Rate:
The debiting from the time credit account takes place, down to the exact minute via logging in and logging off (for both telephone and modem access).
