I set up my parents in public mobile, was a pain in the butt because i had to use their email addresses to talk to the rep for putting in issues. I think it would be nice to be able to set up an administrator for an account.
Not all people are able/willing to set up a PM account. My ostentatious wouldn't switch to PM even though it was better for them unless i dealt with it all since they can't just go in to the store and have a rep set it up. But now any time they want to fix a problem it make a change, i have to get them to come over so i can use their email accounts to contact public mobile.
It would be better if they had a joint account which i was administrator for so i could deal with any changes for them.
