Terms of Service
The rules for selling your device to MonsterBuyBack by mail.
Last updated October 18, 2026
Agreement
These Terms of Service ("Terms") apply when you use MonsterBuyBack.com, request a quote or sell us a device by mail. They are an agreement between you and MonsterBuyBack LLC, doing business as Monster Mobile ("MonsterBuyBack," "we," "us"). By submitting a quote request or an order you agree to these Terms and to our Privacy Policy.
Who can sell to us
To sell us a device, you confirm that:
- you are at least 18 years old and live in the United States;
- you are the lawful owner of the device, or have the owner's permission to sell it;
- the device is not lost or stolen and has a verified clean IMEI (not blacklisted by a carrier or manufacturer);
- the information you give us is true and complete.
We check every device against stolen, lost and blacklist records. We do not buy stolen devices, and we may report them and hold them for law enforcement. We may decline any device or order.
Quotes and your 21-day price lock
Our prices are posted on the site. When you complete the quote tool, your offer is based on the model, storage, carrier and condition you choose. For devices we quote by hand, we email your offer, usually within 1 business day.
Your offer is locked for 21 days from the day you get it. Your device must be shipped (scanned by the carrier) within those 21 days to keep the locked price. After that, we use our current price for your device. Every offer is confirmed at inspection.
We buy devices for payment by PayPal, Venmo, Zelle or check only.
Shipping and insurance
After you place an order, we email a free prepaid USPS label. Pack your device securely, use the label within your 21-day lock, and keep your drop-off receipt.
- Shipping insurance: each prepaid USPS Priority Mail label includes up to $100 of USPS insurance at no cost. Shipping something worth more? Email info@monsterbuyback.com before you ship and we'll add extra coverage to your label.
- If a package is lost or damaged in transit, we file the claim with the carrier. Your recovery is limited to the insured amount on your label. Packages sent without our label, or packed so poorly that the carrier denies the claim, are not covered.
Inspection and revised offers
When your device arrives, we inspect it and compare it with the answers you gave.
- If it matches, we pay your offer.
- If it is different (for example, a different model or storage, more damage, a missing part, or a carrier lock), we email you a revised offer that explains what we found.
- You can accept the revised offer, or ask us to return your device free.
- If we don't hear from you within 7 days of the revised offer email, the revised offer is accepted and we pay it out.
iCloud, Google, Samsung and FRP locks
Before you ship, turn off Find My / Activation Lock and remove all iCloud, Google (Factory Reset Protection), Samsung and MDM accounts. A device that is still locked cannot be tested, resold or paid for.
If your device arrives locked, we pause your order and email you instructions to remove the lock remotely. Once the lock is removed, we finish inspection and pay you. If the lock cannot be removed, you can ask us to return the device free.
Payout
We pay 1 business day after inspection (after you accept any revised offer, or after the 7-day window ends) by the method you chose: PayPal, Venmo, Zelle or mailed check. Business days are Monday to Friday, excluding federal holidays. Checks also depend on mail delivery time. You are responsible for giving us accurate payout details. A payment sent to the details you gave us is final.
Ownership of the device passes to us when we send your payment. We are not responsible for fees your payment provider charges you.
Returned and rejected devices
If you decline a revised offer, or we cannot accept your device (for example, it can't be unlocked), we return it to your shipping address at no cost, as received. We do not return devices that are reported stolen or that we must hold for law enforcement. If a return is undeliverable and we cannot reach you for 90 days after our last attempt, we may recycle the device.
Once you have been paid, the sale is final and we cannot return the device.
Your data
You are responsible for backing up and erasing your device before shipping. We wipe every device we buy with a factory reset before resale or recycling, but we are not responsible for data, photos, files or accounts left on a device you send us, or for the loss of any accessories, SIM cards, memory cards or cases you include. See our Privacy Policy.
Text message terms
By giving us your mobile number and agreeing to texts, you agree to receive text messages from MonsterBuyBack about your quote and order, and marketing texts only if you separately agree to them. We do not sell or share your mobile number or SMS opt-in consent with third parties for their marketing.
We text from the MonsterBuyBack business number. If you give us your mobile number and agree to receive texts (for example, by checking the text box on our forms or by texting us first), we may send you messages about your quote, order, shipping label, inspection, revised offer and payout. We send marketing texts only if you separately agree to them.
- Frequency: message frequency varies, based on your quote and order activity.
- Cost: msg & data rates may apply.
- Opt out: reply STOP to any text to stop receiving texts. We will confirm, then stop. Reply START to opt back in.
- Help: reply HELP for help or email info@monsterbuyback.com.
- Agreeing to texts is not a condition of selling to us.
- Mobile carriers are not liable for delayed or undelivered messages.
Fair use and fraud
Don't misuse the site, submit false information, or try to sell devices you don't own. We may cancel orders, decline or recover payments, and report suspected fraud to law enforcement.
Limitation of liability
The site and our services are provided "as is." To the fullest extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for lost data or lost profits. Our total liability for any claim about a device or order is limited to the amount of the offer for that device. Nothing in these Terms limits any right you have that cannot be limited by law.
Brand names such as Apple, iPhone, iPad, Samsung, Galaxy, Google and Pixel belong to their owners. We are not affiliated with or endorsed by them.
Governing law and disputes
These Terms are governed by the laws of the Commonwealth of Pennsylvania, without regard to conflict-of-law rules. Please contact us first so we can try to fix any problem. Any dispute that we cannot resolve will be handled in the state or federal courts serving Franklin County, Pennsylvania, or in small claims court where you qualify.
Changes to these Terms
We may update these Terms. Changes apply to orders placed after the "Last updated" date. The Terms in effect when you placed your order apply to that order.
