Frequently Asked Questions
Your iPhone Duo's value depends on a few key factors:
- Storage capacity: 256GB, 512GB, 1TB or 2TB (higher storage = higher offer)
- Carrier status: unlocked phones get the best payout
- Inner folding display: cracks, dead pixels or flickering
- Outer cover display and body: scratches, dents or cracked glass
- Hinge: how smoothly it opens, closes and folds flat
Tip: Choose your carrier, storage and condition above to see today's price with an instant, no-obligation quote. Selling a different model? Browse all iPhone models we buy.
Yes. Your carrier status is one of the biggest factors in your offer.
- Unlocked: the best payout, because the phone works on any network
- AT&T, Verizon or T-Mobile: still accepted, with a competitive cash offer
How to check if your iPhone Duo is unlocked:
- Open Settings > General > About.
- Look for Carrier Lock.
- If it says "No SIM restrictions", your phone is unlocked.
Not sure about your status? Contact our team.
Our quote form asks about this first because it affects your offer. Here's how each status is handled:
- Financed (balance still owed): priced differently from paid-off phones. For the best payout, pay off the remaining balance with your carrier before selling.
- Activation locked: Find My must be turned off before we can complete your order.
- Blacklisted: priced differently from clean devices, so select this option if it applies.
Important: Answer honestly so your quote stays accurate after inspection. Unsure about your phone's status? Contact our support team before shipping.
Yes, we buy broken iPhone Duo phones. Common inner display problems we accept include:
- Cracked or shattered inner folding screen
- Flickering, black or unresponsive display
- Dead pixels, lines or discoloration
- Peeling or bubbling factory screen protector layer
Note: A faint crease along the fold is normal on foldable phones and isn't treated as damage.
Select the condition that best describes your phone so your offer stays accurate. Even a damaged foldable still has valuable parts.
You can still sell it. Hinge problems are common on foldable phones, and we accept iPhone Duo phones with:
- A stiff, loose or wobbly hinge
- Grinding or clicking noises when folding
- A gap when the phone is closed
- A screen that won't open fully flat
We also buy phones with a cracked outer cover screen, back glass damage or a faulty camera. Just choose a damaged condition in the quote form and we'll make you a cash offer.
Activation Lock must be removed before we can process your phone. Here's how:
If you still have the phone:
- Open Settings and tap your name at the top.
- Tap Find My > Find My iPhone.
- Switch it off and enter your Apple Account password.
If you've already shipped it:
- Sign in at iCloud.com and open Find Devices.
- Select your iPhone Duo.
- Choose Remove This Device.

Follow these steps to protect your data before you ship:
- Back up your data to iCloud (Settings > your name > iCloud > iCloud Backup > Back Up Now) or to your computer.
- Unpair your Apple Watch if you use one with this phone.
- Erase the phone: go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
- Wait until the phone restarts to the Hello screen. It's now ready to ship.
Why it matters: Erasing protects your photos, messages and Apple Pay cards and helps your phone pass inspection faster.

- No need to rush shipping your iPhone Duo
- Protection from price drops during the lock period
Keep in mind: your phone needs to arrive within the 30 days and match the condition you selected to get your quoted price. Learn more on our FAQ page.

- Zelle
- Venmo

Packing tips for a foldable phone:
- Close the phone so the inner folding screen is protected.
- Wrap it in bubble wrap or soft packing material.
- Place it in a small, sturdy box so it can't move around.
- Seal the box, attach your label and drop it off with the carrier.
Your payment is sent once your phone arrives and passes inspection. Questions about your shipment? Contact our support team.
If our inspection finds a difference, such as an unmentioned crack, hinge issue or a different storage size, we'll send you a revised offer with an explanation before anything is paid.
You then have two choices:
- Accept the revised offer and get paid, or
- Decline it and we'll send your phone back with free return shipping.
Tip: Describe your phone's condition honestly when getting your quote to avoid any changes. Learn more about us on our About Us page.
