Replacing iPhone 6 plus at Apple store

Yes, you're still obligated to pay off the remaining balance if that's what you're wondering

 

Have you used your SIM card in the replacement device? If you did, the IMEI registers with the network almost immediately, and that would be the new IMEI associated with your installment plan. The person you sell it to will be able to use it, but if the payment on the device is more than 30 days late, that IMEI gets blocked.

 

Pretty much, yes.

 

Proceed with some kind of caution though, as what you're doing kinda stinks of retail fraud

 

If it works as it does here in the UK then the replacement phone from Apple is like for like.

So if it it locked to a network the replacement phone will also be locked.

 

Where's the fraud? He took his phone to the Apple Store. It's under warranty. They replaced it. I fail to see the fraud here.

 

It doesn't. My iphone was locked to T-mobile. I just had to have it replaced due to network issues. The refurbed phone is unlocked.

 

The activation profile is carried from the phone that is replaced. Tmobile iphones are unlocked standard.

 

Every time I have gone to the Apple Store to get a replacement device, the genius always has inserted my SIM card into the new phone.
