  • Would I be able to switch carriers without having to switch phones? I'm with Consumer Cellular and I have an iPhone SE, but I'm thinking of switching carriers so that I can get unlimited data. I don't want to get a new phone because I've had my current one about six months, I really like it, and it works great. I'm not locked into a contract with Consumer Cellular. Would I be able to switch to another carrier without having to purchase a new phone?

  • How to unlink my Outlook account and my Gmail account? A while back, I linked these accounts together somehow (it's been so long I forgot how) so I would only have to access one account to read all my email, but now when I get an email in my Gmail account, I get that exact same email in my Outlook account a few minutes later, and I keep getting notification noises on my iPhone and have to spend time deleting the extra emails. It's really annoying me and I want to undo it, but I don't know how!
  • How to switch from my current iTunes account to a new one on my iPhone? I currently share my own iTunes account with my mom, sister, and brother. It gets really annoying at times because i don't want to download apps like piano, racing games, and weird picture editors. Is there anyway that i can transfer to another itunes account on my iPhone (sorry, forgot to mention) without ruining their items? Also, will my phone be reset if i do switch it? Please help me. I just can't take the sharing of my own acount anymore.
