Jitterbug's billing is deceptive, if not illegal. It's a scheme to bilk elderly customers at an inflated rate. Customers cannot get an accurate tally on how many minutes are left CURRENTLY. You have to wait 3 days after your inquiry to know where you stand with usage! They say the reason is that Jitterbug is a 3rd party carrier and that is also the reason why there is an average of 20-25 seconds of dead air before you hear a dialed number is ringing. Lastly, the customer service is the worst I've encountered in years. Yes, the buttons are large, but that's not enough incentive to put up with the billing rip offs and horrible customer service.
