HandsetWise: Used Phone Check

Thinking of buying a used phone or second hand phone? HandsetWise is a used phone checker that helps you check what you can before you pay: validate the IMEI number, compare it with the box and go through a test checklist. It is plain about what it can't check.

IMEI NUMBER FORMAT CHECK, EVEN OFFLINE
Type the 15 digits and see whether the number is well formed. A valid format only means that: it doesn't show that a phone is clean, unlocked, paid off or not stolen.

DO THE NUMBERS MATCH?
Compare the IMEI on the phone with the box and the listing. Dual SIM phones can use a second number, so the app lets you add both.

USED PHONE TEST CHECKLIST: 25 THINGS TO TEST
A checklist for when you meet the seller: previous owner locks first, then screen, battery, body, camera, sound and signal. Items marked as must-pass tell you when to stop.

CHECK A LISTING WITH AI
Add a listing screenshot, a box photo or the Settings screen. The AI assistant reads them, grades the red flags from A to F and tells you what to do next. A good grade only means no red flags in what was read.

QUESTIONS FOR THE SELLER
Copy a ready list of questions, such as asking for an erase in front of you and a receipt.

OFFICIAL LOOKUPS
Links to lookups run by others for Türkiye (e-Devlet with BTK), India (Sanchar Saathi), Peru (OSIPTEL) and the United States (CTIA). You check them yourself. For other countries, ask your carrier or telecoms regulator.

WHAT THIS APP DOES NOT CHECK
HandsetWise has no blacklist data. It does not check whether a phone is blocked by a network, reported lost or stolen, or still being paid for, and it never promises a phone is clean.

Light and dark mode, and the app follows your phone's language.

IMPORTANT
HandsetWise is an AI assistant and can make mistakes. It is not affiliated with any phone maker, carrier, marketplace or government agency. Test the phone yourself before you pay.
