A new phone is the one purchase that makes otherwise sensible people panic.
Everything is on the old one.
Years of family WhatsApp groups, photos nobody else has, the bank app.
Meanwhile someone at the shop is offering to move it all in five minutes.
I have set up a lot of new phones for a lot of people in Mumbai.
Hardly any of the losses I have seen were the technology failing.
They happened because the steps were done in the wrong order.
Who is this for?
Anyone with a new phone still in the box, or about to buy one.
It is equally for the son, daughter or nephew handed the job.
Nothing technical is assumed.
Android and iPhone are both covered, including moving from one to the other.
What changes by the end?
You sign in, and your photos, contacts and files arrive on their own.
WhatsApp opens with every chat and voice note in place.
Your bank app asks for a code, and your authenticator app has it ready.
Calls and messages come to the new handset instead of the old one.
The old phone is signed out, wiped properly, and safe to sell or hand down.
Nothing lost, and nothing of yours left on a phone somebody else now owns.
Why does the order matter so much?
Because for a few hours your old phone holds the only copy of some things.
People wipe it, trade it in or give it to a cousin far too early.
That is the most common way people lose data.
Nothing is deleted from your old phone during a switch.
You are copying, not moving.
Leaving it charged in a drawer for a few days costs nothing.
What is the shape of it?
Five steps, in a fixed order, and the order is the whole trick.
First, five quiet minutes on the old phone.
Run a full backup and confirm your Google or Apple ID password.
Charge both phones and get on Wi-Fi.
Then photos and contacts, then WhatsApp, then apps and two-factor codes.
Your number and the wipe come last.
Do photos really move on their own?
Yes, if they are already syncing to Google Photos or iCloud Photos.
Open it on the old phone and wait until backup is complete.
Files kept in Google Drive or iCloud Drive need nothing at all.
Contacts are where people come unstuck.
Contacts saved to the SIM card, or "on this phone only", never reached your account.
So your account cannot hand them over.
You sign in to a beautiful new phone and the address book is empty.
What about WhatsApp?
WhatsApp needs its own backup, taken on the old phone before you start.
Android saves that backup to Google Drive, and iPhone saves it to iCloud.
Android to Android and iPhone to iPhone both restore from it.
Crossing between Android and iPhone is a different job.
A backup will not restore at all across that line.
That route uses the official transfer tool, with a cable, during the new phone's setup.
So do not race through those first setup screens.
Which step locks people out?
Two-factor codes.
Two-factor means the six-digit code your bank or email asks for after your password.
Usually it comes from an authenticator app.
Apps and passwords are the easy half of that step.
You reinstall apps from the store, and past purchases are remembered.
A password manager fills your logins in automatically.
But those six-digit codes live on the phone itself, not in your account.
Factory-reset the old handset before moving that app, and you lock yourself out of email, bank and work.
So the authenticator moves before any other app, while the old phone still works.
Google Authenticator has cloud sync, or an export-and-scan option.
Authy and Microsoft Authenticator restore from their own cloud backup.
No backup at all?
Printed backup codes let you set the security up again on the new phone.
Every one of those routes needs the old phone alive and working.
What is left at the very end?
Your number, a proper check, and then the wipe.
A physical SIM just moves across in the tray.
An eSIM is built into the phone, so there is nothing to remove.
That one moves through your carrier's app, or a QR code.
Then open the gallery, the chats, the contacts and the authenticator.
Look at them with your own eyes.
A tick on a transfer screen is not proof that your 2020 photos came along.
Only then sign out of your Apple or Google account.
Sign out before the reset, never after.
Skip that and the next owner gets a handset that will not activate.
Erase all content and settings, take the SIM out, and it is done.
Things to Remember
- Treat the switch as five steps in order, not one rushed evening.
- Nothing is deleted from the old phone, so keep it charged for a few days.
- Move your authenticator app before any other app on the new phone.
- Check your contacts sit in your Google or iCloud account, not on the SIM.
- WhatsApp needs its own backup, and crossing between Android and iPhone needs the transfer tool.
- Sign out of the old phone before you erase it, once you have seen everything arrive.
