Canceling or removing Backup Assistant
Canceling a Backup Assistant subscription or removing it deletes the application from the handset completely. Airtime / megabyte charges apply while removing a subscribed application. Images may vary depending on the handset model.
Backup Assistant isn't $5/month. In fact, you shouldn't be charged at all for Backup Assistant if you have a MyVerizon account. if you are seeing a $5/month charge under Get It Now downloads then it may be the Mobile Email application, or some other application or even game. Check the Browse & Download, Games and Tools on the Go menus to find any applications that may be installed on your phone.
Nearly every application can be removed in the same manner that Backup Assistant can.
How do I get rid of the $5/month charge?
First of all, chile is right - Backup Assistant does not cost $5 a month - that charge has got to be for something else.
Second, I would not recommend getting rid of Backup Assistant - it's FREE with a MyVerizon account, and both BA and a MyVerizon account are very good things to have and cost you nothing. Find out what the $5 is for and get rid of that if necessary, but don't get rid of BA!
