I am on 12gb plan I think if public mobile offer unlimted calling usa add on that would be a great idea instead of 8 dollars for 200 min and 15 dollars for 400 mins if they offer unlimited add on 30 days without rolling over since it's a unlimted talk add on that would be a great option so users select add on according to their needs user will have 3 opting to select from I would say lots of people's will get attractive to add on since now days lots of other carriers try to attract or get more user by offering can/usa calling plan it's would be a great option if we get offered unlimted calling to usa 30 days add on
