5 Proven Tips to Maximize Your Trade-In Value
To ensure you get the top dollar when you sell iPhone for cash or use our Samsung phone trade-in service, follow these expert tips:
- Remove your iCloud/Google Account: A device with Activation Lock is considered “broken” and significantly drops value.
- Factory Reset: Wipe all data to protect your privacy and present a “clean” device.
- Original Accessories (Optional): While not required, including the original box can sometimes bump the quote by $5–$10.
- Be Honest About Condition: Overstating the condition leads to renegotiation. We pay the highest for “Flawless” but offer fair prices for cracked screens too.
- Compare Carrier Lock Status: Unlocked phones fetch higher value, but we specialize in buying AT&T locked devices as well.
Common Mistakes That Cost You Cash
Even savvy sellers make errors. Avoid these pitfalls to ensure your transaction stays smooth:
- Not backing up photos: Losing memories is a pain. Back up before resetting.
- Leaving the SIM card inside: Always remove your SIM to prevent data breaches.
- Waiting too long: Phone values depreciate monthly. Sell while demand is high—especially after a new iPhone release.
- Choosing the wrong buyer: Don’t settle for store credit when you can get instant cash for your old device with our mobile buyback service.
