How to Transfer Data Between Phones in 2026: Complete Guide (All Scenarios)

Switching phones is one of those tasks that looks simple but hides a dozen ways to lose data you won’t miss until three months later. A game you’ve played for two years. Voicemails from people who have since passed. Two-factor authentication codes that lock you out of accounts. The photos from a trip you never fully backed up.

This guide covers all four switching scenarios — Android to Android, iPhone to iPhone, Android to iPhone, and iPhone to Android — plus the checklist of things that don’t transfer automatically and how to handle them.

Before You Start: Pre-Transfer Checklist

Do this the day before, not the day of.

• Charge your old phone to at least 80%
• Connect to a strong Wi-Fi network (you’ll be moving gigabytes of data)
• Note down your Apple ID or Google account credentials
• Back up your 2FA app separately (see below)
• Download voicemails you want to keep
• Check which games or apps don’t have cloud saves
• Have a USB-C to USB-C cable (or Lightning to USB-C for older iPhones) handy

Time estimate: 1–3 hours total, depending on data volume and method.

Scenario 1: Android to Android (Easiest)

Google’s backup system and Samsung’s Smart Switch both handle this well.

Using Google’s Built-In Transfer (Any Android to Any Android)

During new phone setup, select “Copy apps & data” and “from an Android phone.” Follow the prompts to connect the two phones via cable or Wi-Fi. Google will transfer:

• Contacts, calendar, and Gmail
• Photos and videos (via Google Photos)
• App list and app data (for supported apps)
• Wi-Fi passwords
• Wallpapers and some settings

What might not transfer:

• Game saves for games without Google Play Games cloud saves
• App data for apps that don’t support Google’s backup API
• SMS history from some third-party apps

Samsung Smart Switch (Samsung to Samsung)

If both phones are Samsung Galaxy devices, Smart Switch is superior. Install it on your old phone (it may already be there), open it on both devices, and connect them.

Smart Switch transfers:

• Everything Google’s method transfers, plus:
• More complete app data
• Home screen layout and widgets
• Samsung-specific settings
• Secure Folder (encrypted, requires password)

Transfer time: 30–90 minutes depending on storage size.

Scenario 2: iPhone to iPhone (Easiest)

Apple’s Quick Start process is seamless.

1. Power on your new iPhone — you’ll see the setup screen
2. Bring your old iPhone close to the new one
3. A “Set Up New iPhone” prompt appears on the old phone — tap Continue
4. Scan the animated pattern on the new iPhone screen with your old phone’s camera
5. Choose “Transfer from iPhone” (direct, faster) or “Download from iCloud” (requires iCloud storage)
6. Enter your passcode on the new device
7. Wait 30–120 minutes

Transfer from iPhone (direct) is the better option if both phones are nearby and plugged in. It transfers at local Wi-Fi speed without iCloud storage limits.

Download from iCloud works well if your data is already backed up and you’re setting up the new phone remotely — but you need enough iCloud storage to hold a full backup.

What transfers completely:

• All apps and their data
• Photos and videos
• iMessages and SMS history
• Health data
• Apple Pay cards (cards are deactivated on old phone)
• Wi-Fi passwords
• Settings and home screen layout

Tip: If you use a password manager like 1Password or Bitwarden, those sync via cloud and you won’t need to do anything extra.

Scenario 3: Android to iPhone (Most Complex)

This is the most involved scenario because you’re crossing ecosystems. Plan an hour for prep on the old phone before you even open the new one.

Step 1: Prep Your Android (Do This First)

• Back up photos: Ensure Google Photos has synced everything. Or connect to your PC and copy the DCIM folder directly.
• Export contacts: Google Contacts should already be synced to your Google account, which you can access on iPhone. If you use a local contacts app, export a VCF file first.
• WhatsApp: In WhatsApp, go to Settings > Chats > Move Chats to iPhone and follow the prompts with a cable connected.
• Note your 2FA apps: Google Authenticator now syncs to your Google account. Authy syncs by default. If you use Microsoft Authenticator, enable cloud backup first.
• Download your Google Authenticator backup (Settings > Transfer accounts > Export accounts) as a safety measure.

Step 2: Use Apple’s “Move to iOS” App

1. On your Android, download “Move to iOS” from Google Play
2. Begin setting up the new iPhone — when asked how to transfer, select “Move Data from Android”
3. A 10-digit code appears on the iPhone
4. Enter that code in the Move to iOS app on Android
5. The two devices create a direct Wi-Fi connection
6. Select what to transfer and wait

Move to iOS transfers: contacts, message history, camera roll, web bookmarks, email accounts, calendar entries, and equivalents for free apps.

What Move to iOS does NOT transfer:

• Google ecosystem apps (Gmail, Maps, Drive) — reinstall and sign in
• Apps with no iOS equivalent — find replacements
• WhatsApp (use the dedicated WhatsApp transfer above)
• App-specific save data for most games
• Text messages sent via Android messaging apps (SMS usually transfers, RCS does not)

Step 3: Post-Transfer Setup on iPhone

• Sign into Gmail, Google Maps, Google Drive, etc.
• Set up Face ID
• Add cards to Apple Pay (your old Android payment cards won’t carry over)
• Enable iMessage — this is important if your number was receiving texts
• Check your 2FA codes work before relying on them

Important: If you were receiving SMS texts on your Android number and switching to iPhone, enable iMessage for your number immediately. Otherwise, people with iPhones will try to send you iMessages that your new phone can’t receive until it’s registered.

Scenario 4: iPhone to Android (Second Most Complex)

Step 1: Prep Your iPhone (Critical)

Deregister iMessage first. This is the most commonly forgotten step. If you don’t do it, iPhone users who text you will have their messages route to your old iMessage account, and you’ll never receive them on your new Android.

To deregister: Go to Settings > [your name] > iMessage, turn it off. Or go to Apple’s website (appleid.apple.com) and remove your phone number from iMessage.

Also:

• Turn off iCloud Photos sync and download originals to the phone first (Settings > Photos > Download and Keep Originals)
• Back up via iCloud one final time
• Note your Apple ID — you’ll still need it for any Apple services

Step 2: Samsung Smart Switch or Google’s Transfer Process

New Samsung phones: Smart Switch can import from iCloud directly. Enter your Apple ID during setup.

Other Android phones: During Google’s setup process, choose to import from an iPhone/iCloud backup.

Either way, you’ll transfer: contacts, calendar, photos, videos, and some app data.

What won’t transfer from iPhone to Android:

• iMessage conversations (Apple-proprietary format)
• FaceTime history
• App purchases (you’ll need to repurchase paid apps on Google Play)
• Apple Watch data
• iCloud-only app data (Notes synced only to iCloud, etc.)

Step 3: WhatsApp, 2FA, and Key Apps

• WhatsApp: Settings > Chats > Move Chats to Android — use a cable for the transfer
• Google Authenticator: Sign into your Google account on the new Android and your codes should sync automatically if you had backup enabled
• Authy: Downloads automatically when you reinstall and verify your phone number

The Items Everyone Forgets

Run through this checklist after completing your main transfer:

Apps and data:

• Authenticator/2FA codes — verify each one works
• Password manager — log in and test
• Banking apps — these often require re-verification
• Game save data — open each game and confirm progress
• Podcast app — re-subscribe and verify episode history
• Streaming apps (Netflix, Spotify) — just log back in, no data loss
• Healthcare apps — verify records transferred or re-sync

Files and media:

• Voicemails — download any you want to keep before switching carriers
• Downloaded files (PDFs, documents in Downloads folder)
• Screenshots you haven’t organized
• Videos you haven’t uploaded anywhere
• Music downloaded for offline playback

Settings:

• Alarms and recurring reminders
• Bluetooth pairings (car, headphones, watch) — you’ll need to re-pair
• Wi-Fi passwords (auto-transfers on same-ecosystem switches; manual on cross-ecosystem)
• VPN configuration
• Email signature

After One Week: The Post-Switch Verification

Give yourself a full week of daily use before wiping the old phone. Then run through:

• Photos: Browse the last 6 months — anything missing?
• Contacts: Call or message a few people from different contact sources
• Banking: Log in and make a small transaction
• 2FA: Trigger a login for each 2FA-protected account
• Apps: Open the 5 apps you use most and verify data

Only after everything checks out: sign out of all accounts on the old phone, remove it from your Google/Apple account, and factory reset.

Selling or Recycling Your Old Phone

Before handing it off:

1. Back up one final time
2. Sign out of Google, Apple, Samsung, and any other accounts
3. Remove the SIM card
4. Factory reset (Settings > General > Transfer or Reset iPhone, or Settings > System > Reset on Android)
5. Confirm the reset completed and the phone shows the setup screen

Where to sell:

• Swappa: Best prices for unlocked phones, lower fees than eBay
• Facebook Marketplace: No fees, cash in hand, local pickup
• Trade-in programs: Apple, Samsung, and carriers offer credit — convenient but usually 20–30% less than private sale
• Decluttr: Easy mail-in, instant quote, lower prices

A well-wiped, fully functional phone still has real resale value. Don’t leave it in a drawer.
