badauss42: Yes, the monthly limit on incoming pages is 150 ... BUT if you access the voice mail over phone, that reduces the number of available minutes too.
They don't mention these anywhere on the page EXCEPT on the sign-on agreement (which 90% of the people don't read anyway) !
I had signed up for this a few months back, but when I came to know about this 'hidden' details, I was totally pissed off and cancelled my service and returned the pager.
Their customer service is also horrible, in my experience.
