Before You Sell or Exchange a Phone: Accounts, Wipes and What a Factory Reset Misses
A reset with your Google or Apple account still signed in leaves the phone locked to you and worthless to the buyer. Here is the order to do things in, and the three things a reset does not remove.

Short answer
What should I do before selling or exchanging my old phone in India?
Before a phone leaves your hands, remove the account lock first and reset last. On an iPhone, sign out of iCloud, which turns off Find My and Activation Lock, then erase and choose to delete the eSIM unless you are transferring it. On Android, remove the Google account and any Samsung or brand account before the reset, because a reset with the account still present leaves Factory Reset Protection engaged and the phone unusable for the next owner. Before either, back up photos and WhatsApp, move authenticator apps, and log out of UPI and banking apps, since UPI is bound to the device and SIM. A factory reset does not wipe a microSD card, does not remove an account lock that was still signed in, and does not release the phone from your Apple or Google device list; do those by hand. Keep the invoice, because an Indian warranty follows the handset and the buyer will need it.
Our practical verdict
Before You Sell or Exchange a Phone: Accounts, Wipes and What a Factory Reset Misses should answer a simple question: what should an Indian buyer actually shortlist today? The answer changes with live prices, but the decision logic stays steady. We look at availability in India, warranty, service access, long-term usefulness, ecosystem fit, and how often the product is discounted during major sales.
Shortlist
Recommended options to compare
Use this as a starting list, then compare live India prices and warranty before buying.
Pick 1
Accounts off first, reset last
The single mistake that ruins a sale is resetting with the account still signed in. On Android that engages Factory Reset Protection, which asks the next owner for your Google login on setup and makes the phone useless to them. On iPhone it leaves Activation Lock on. Exchange pickups check for exactly this and reject the phone at the door. Remove the Google, Apple, Samsung or brand account, confirm Find My or Find My Device is off, and only then reset.
Pick 2
Back up, and move the two things people forget
Photos and contacts usually sync already. WhatsApp needs a chat backup taken deliberately, and its linked devices unlinked. The costly miss is authenticator apps: move Google Authenticator through its cloud sync or export, and Microsoft Authenticator through its backup, before the reset, because losing them locks you out of every account they protect and recovery takes days.
Pick 3
UPI and banking are bound to the device
UPI apps bind your account to the SIM and the handset. Log out of every UPI and banking app on the old phone and remove the SIM, then set up fresh on the new one. A reset clears the app, but doing it explicitly is what ensures nothing is left registered against a phone you no longer hold.
Pick 4
The three things a reset does not touch
A microSD card is not wiped by a reset and holds your photos in the clear; take it out. An account lock that was still signed in survives the reset, which is the point above. And the phone stays listed in your Apple or Google device list until you remove it there, which matters for the buyer's setup and for your own records. Modern phones encrypt storage by default, so the reset itself is secure once these are handled.
Pick 5
eSIM: delete or transfer, do not leave it
Erasing an iPhone offers to keep or delete the eSIM; delete it unless you are moving it to the new phone through the carrier's transfer flow. On Android, delete the eSIM profile before the reset. An eSIM left on a sold phone is a line still tied to you.
Pick 6
Keep the invoice, note the IMEI
Indian brand warranties follow the handset, not the owner, and the buyer will need the invoice for any service visit. Dial *#06# and record the IMEI before handing the phone over, so you have it if the device is later reported lost or misused. The genuine phone guide covers the checks the buyer will be doing on their side.
Pick 7
Exchange versus sale changes the order, not the list
For an exchange pickup, everything above has to be done before the delivery person arrives, because the inspection is at the door and a locked phone converts your exchange discount into a full-price purchase. For a private sale you have more time, and the phone value calculator and the exchange offer guide together tell you whether the private sale is worth the extra effort.
Before you buy
- Remove the Google, Apple and brand accounts before the reset, never after. A reset with an account still signed in locks the phone to you and is rejected at exchange pickup
- Move your authenticator apps before anything else. They are the one thing that cannot be recovered from a backup you did not make
- Log out of UPI and banking apps and remove the SIM. UPI is bound to the device and SIM and should be set up fresh on the new phone
- Take out the microSD card. A factory reset does not wipe it
- Delete or transfer the eSIM rather than leaving it on the phone. If the screen is the reason for the upgrade, the phone display guide is where to start on the new one
- Keep the invoice and record the IMEI. See the exchange offer guide for whether trading in beats selling, and the genuine phone guide for what the buyer will check
