Got questions?
Frequently asked questions
Clear answers on how prices, doorstep pickup and payments work.
How is my phone's price worked out?
Each model has a top price for a phone in perfect condition. Your answers about the screen, body, working parts and accessories adjust that price. The price is calculated on our server, so it is the same for everyone who gives the same answers.
Is doorstep pickup really free?
Yes. Pickup and inspection are free in all the areas we serve. There are no hidden travel or convenience charges.
When and how do I get paid?
On the spot. After our executive checks the phone (about 5 minutes), you choose UPI, bank transfer or cash. The money reaches you before you hand over the phone.
My phone does not switch on. Can I still sell it?
Yes. Choose “No” when we ask if the phone switches on and answer the other questions honestly. You will still get a price, and pickup is free.
How long is my price valid?
Your quote stays valid for 48 hours. If the phone's condition at pickup matches your answers, you get exactly that price.
Do you offer same-day pickup?
Yes, in the cities we serve. Book before 2 PM and we can usually pick up the same day. Check your pincode on the price page.
Can I cancel my pickup?
Yes, free of charge: call or WhatsApp us, or simply tell the executive at your door before the check is finished. You can also change the pickup time on your booking page.
What documents do I need?
Only one government photo ID, such as Aadhaar. Our executive asks for it only after inspecting the phone and agreeing the final price, and it goes on your bill of sale.
What happens to my personal data?
Please back up and sign out of your accounts. We factory-reset the phone in front of you and then wipe it fully at our facility.
What if my pickup is late?
Track your pickup any time with your booking ID. If we are running late we will tell you on WhatsApp or SMS, and you can move to a new slot for free.
Need help with a pickup you've booked?
Enter your booking ID to check its status, or ask us to change the time.
