Are iPhones from the Apple store as same as those from AT&T store?

I have AT&T plan and I want to get a new iPhone 5c at the apple store, cuz my local att store is closed, but i don't know if the apple store give the same phone as att. I know there are different setup, depends on which phone carrier you have.
And do the iPhones from Att have less quality than ones from Apple store? Or they're the same?

Yes, they are both overpriced junk made by children being paid 10-cents a day.

  • Will all data share across devices on iPhones with the same Apple ID? My dad recently got an iPhone 4s for his birthday and I currently have an iPhone 6. My iMessages went on to his phone without me putting on any sharing settings. I do not have iCloud or anything like that. I was wondering if any other things will go through on his phone
  • Two iPhones using the same Apple ID account I recently got the iPhone 5S and everything is fine with that. Prior to that, I had the iPhone 4S. The 5S is activated with my cell provider and the 4S has been deactivated. I want to use the 4S sort of like an iPod Touch. I'm using the same Apple ID on both devices. Whatever I do on one, take pics, edit contacts, etc, it shows up on the other device. I was wondering if there's a way to use the same Apple ID but not have the changes transfer over to the other device?
  • My mom and i got the same phone and same plan yet her internet loads all the time and mine never does? Two iPhone 7+. Same unlimited data plan. Yet literally no matter where I'm, nothing that uses data loads unless I'm connected to Wi-Fi. Yet my mom's internet loads no matter where she is. It's even happened that we're in the same place trying to load the same thing and hers loads while mine doesn't. Yes, I have my data turned on. I've made sure all my data settings are identical to my mom's. So i really don't know what could be causing this.
