Data messed up! Why?

Question

Two phones have recurring data at exact same times daily.  Why? Also, recently purchased new phone, arrived in mail, not activated yet---daughter at college, still using old phone.  Her old phone now shows she hasn't used data for 20 days (it was documented before).  Also seems like her data is now showing on other phones.  Customer service said purchasing the new phone has nothing to do with what shows for data.  It makes no sense.  Purchasing the new phone is the only thing that has changed.  Data documentation has been fine before that!

Answer 1

Whatever you've done already it's the wrong thing to do. You cannot arbitrarily change permissions on every file on your backup using the Get Info window. The result will be a complete screwup of all the file permissions on your backup. You will manage to make a simple problem into an unsolvable one.
Next time you should ask first before you act rather than after when you cannot go back. Since you did this to your TM backup drive about all you can do at this point is erase the drive and start your TM backups from scratch. Of course this doesn't resolve anything for whatever you tried to migrate to your new computer.
If you migrated your old Home folder to the new computer then first be sure the account has admin status, then log into the account. You should then have full access to all your restored files. You can then delete the other user account.
