How does the monthly cost (i.e., all the YBB & NTT billed fees ex. tolls for calls that are billed monthly) compare?
• If you use YBB on a ‘rented’ (Lite) phone line: 376 yen more per month than Non-NTT type • If you use YBB on an regular “owned” NTT line: From 149 yen less to 113 yen more per month than Non-NTT type and must own or buy line. • If you use YBB without NTT: From 149 yen more to between 113 and 376 yen/month less than NTT type.
