What should I check before buying an unlocked replacement iPhone?
Answer
Confirm your carrier accepts unlocked iPhones, compare unlocked retail pricing, verify the model’s network bands, and plan how you will move your number and apps before you buy.
Before you start: stop right away if…
- Avoid sellers who demand gift-card or wire payment for a “discount unlocked” phone.
Follow these steps
Confirm carrier compatibility
Check your carrier’s bring-your-own-phone page for unlocked iPhone requirements and supported models.
You should see: You know which iPhone models are listed as compatible.
Compare unlocked pricing
Check current unlocked iPhone prices at reputable retailers and note return windows and taxes.
You should see: You have a realistic price range for the model you want.
Plan number and data move
Back up the old phone, remove or request an eSIM transfer from your carrier, and keep the old phone until the new one makes calls.
You should see: You have a backup and a clear transfer plan.
Inspect unlock and Activation Lock at setup
On first boot, confirm setup does not demand someone else’s Apple ID. Place a test call on your carrier after activation.
You should see: The iPhone activates on your account and can call and text.

Extra tips
What to look for: Listing text that says “Unlocked,” carrier compatibility notes, and whether Activation Lock is off on used devices.
Before you change anything: Know your current carrier and whether your number can transfer. Back up your old phone first if it still powers on. Avoid deals that require wire transfers or gift cards.
