Moving to a new flagship smartphone, especially iPhone 15 Pro Max, is always an exciting process, which begins with the most important task: saving and transferring the phone book. Losing the numbers of colleagues, friends or delivery services when changing the operating system from Android to iOS is extremely unpleasant, but modern technologies allow you to avoid this problem. There are several proven methods for migrating data, each of which has its own characteristics and is suitable for different use cases.
In this article we will look in detail at how to safely and quickly move your records using official Apple utilities, Google cloud services or standard file formats. Whether you've already purchased a new phone or are just planning to buy it, you'll find a solution here. The main thing is to take your time and carefully follow the steps so that there are no duplicates or synchronization errors.
Before you begin any active steps, make sure that both devices are charged and have access to a stable Wi-Fi network. This is a basic requirement for most methods, as transferring large amounts of data can take time. It is also worth checking that iPhone has the latest version of iOS available at the time of unpacking.
Preparing devices for data migration
The first and most critical step is to properly prepare the source device based on Android. Often users neglect this step, which leads to errors in the process. You need to make sure that all your contacts are actually saved in the phone memory or on your Google account, and not just on the SIM card, which has limited functionality.
Go to the settings of your Android smartphone and check the operating system version. For the application to work correctly Move to iOS requires Android version 4.0 or later, but for stability it is better to have more recent software. Also free up memory space if you plan to transfer not only contacts, but also photos or videos.
⚠️ Attention: If you have already started using your iPhone and created new contacts on it, a version conflict may occur when synchronizing with your Google account. It is better to start transferring to a clean device or make a backup copy of your current iCloud data.
On the Apple side, you also need to perform a number of steps. If your iPhone is already activated and you're on your desktop, you'll have to reset it to factory settings to launch the First Time Setup Wizard, where the functionality you need is available. This is a prerequisite for the native Apple method to work.
- 📱 Make sure that Wi-Fi on your Android device is turned on and stable.
- 🔋 Connect both smartphones to chargers to avoid draining.
- 🔄 Update applications to the latest versions via Google Play or App Store.
- 📶 Disable power saving mode on both devices.
☑️ Ready for transfer
It is important to understand the difference between on-the-fly transfer and restoring from a backup. In the first case, data is transmitted directly between devices, in the second, an archive is first created, which is then deployed. For contacts the difference is minimal, but for multimedia it significantly affects the wait time.
Move to iOS method: official method from Apple
The most preferable option for most users is to use a special application Move to iOSdeveloped by Apple engineers. This tool is designed specifically for migration from Android to iOS and provides encryption of the transferred data. The process does not require a computer and is performed completely wirelessly.
To get started, you need to download the application Move to iOS from the Google Play store to your Android smartphone. On an iPhone, during the initial setup, at the “Applications and Data” stage, you need to select the “Transfer data from Android” option. After this, a six- or ten-digit code will appear on the iPhone screen.
Enter this code in the appropriate field on your Android device. Smartphones will create a temporary protected Wi-Fi network through which the data flow will flow. All you have to do is choose what exactly you want to transfer: in this case we are interested Contact, but you can also transfer messages, photos and even web browsing history.
The transfer speed depends on the amount of data and the quality of the wireless connection. Do not switch to other apps on Android during the process as this may break the connection. Once completed, a success message will appear on your iPhone and you can continue setting up.
| Option | Android | iPhone (iOS) |
|---|---|---|
| Application | Move to iOS | Built into the system |
| Connection type | Local Wi-Fi network | Local Wi-Fi network |
| Requirements | Android 4.0+ | iOS 9.0+ |
| Transfer WhatsApp | Supported | Supported |
What to do if the code is not accepted?
If the code does not work, check if the "Mobile data" mode is enabled on Android. Sometimes switching to a cellular network interrupts the device search process. Also try rebooting both phones and starting over, making sure Bluetooth is turned on on both devices for the initial handshake.
Once the migration is complete, all your entries will appear in the Phone or Contacts app. The system will automatically distribute them into the following fields: name, number, email. If you had records with several numbers, they will also be saved correctly.
Synchronization via Google account
An alternative and often more flexible method is to use a cloud profile Google. Many Android users store their contacts there without even thinking about it. If your numbers are linked to Gmail, the process of switching to iPhone 15 Pro Max becomes elementary and does not require installing additional software on the old device.
The essence of the method is to add your Google account to the iOS settings. Go to the Settings → Contacts → Accounts section (the path may vary slightly depending on the iOS version). Click "Add an account", select the Google logo and enter your data.
After authorization, the system will ask what data needs to be synchronized. Make sure the switch next to Contacts is green. In a few minutes (or seconds, if there are few entries), the phone book will be completely updated, pulling data from the Google cloud.
- 🌐 Instant synchronization if the Internet is available.
- 🔄 Two-way communication: changes on the iPhone will be reflected in Gmail.
- 🛡️ High reliability of data storage on Google servers.
- ⚙️ Ability to select specific groups for synchronization.
This method is especially convenient for those who plan to use Google services (Mail, Maps, Drive) on the new iPhone. You get a single ecosystem where contacts are available from any device, be it a computer, tablet or other smartphone.
⚠️ Attention: When synchronizing via Google, make sure that you select the exact account where the contacts are saved. If you have multiple emails, check contacts.google.com in your browser on your computer to see where the numbers you need are located.
It is important to note that when you turn on synchronization for the first time, your iPhone may ask what to do with existing local contacts. The system will offer to combine them or replace them. Select "Merge" so as not to lose those rare numbers that could only be recorded in the phone's memory.
If there are a lot of contacts (more than 2000), initial synchronization may take up to 15-20 minutes. Don't lock your iPhone's screen during this time and keep it connected to Wi-Fi to speed up the process.
Transfer via vCard File (VCF)
If you don't have access to Wi-Fi or prefer manual file management, the method using the format vCard (.vcf) will be an excellent solution. This is a universal standard that is supported by almost all phone books in the world. The vCard file contains all information about the contact in text form.
On your Android smartphone, open the Contacts application, call up the menu (usually three dots or the Manage button) and select Import/Export. You need to export your contacts to a .vcf file. The system will offer to save it to internal memory. After creating the file, send it to yourself by email or upload it to cloud storage (Dropbox, Yandex.Disk) to have access from your iPhone.
On iPhone, open the received letter or file in the Files application. When you click on the .vcf file, the system will recognize the format and offer to add all found contacts. You will see a list of imported entries and the "Add all" button.
Path for export to Android:
Contacts → Menu (three dots) → Manage contacts → Import/export contacts → Export to file.vcf
This method is good for its autonomy: it does not require the Internet at the time of transfer (if the file has already been transferred) and does not depend on Google or Apple servers. However, it does not provide constant synchronization: if you add a number on Android after creating the file, it will not automatically appear on iPhone.
The vCard file is an ideal choice for a one-time transfer of a large archive of contacts without being tied to cloud services and an Internet connection at the time of migration.
After importing, be sure to check several random contacts. Sometimes encoding errors may occur in vCard files, due to which Russian letters turn into gibberish, although this rarely happens in modern versions of iOS and Android.
Using a SIM card for migration
The oldest, "old school" method is transfer via SIM card. It is suitable only if your SIM card has enough memory to store contacts (usually this is limited to only the number and name, without email, photos and addresses) and if the numbers are stored on it, and not in the phone's memory.
The process is simple: on Android, go to contact management and select "Copy contacts" → "C SIM cards to phone" (to make sure that they are there) or vice versa, "From phone to SIM card". After recording, insert the SIM card into the iPhone 15 Pro Max (using the tray or eSIM if the operator supports profile transfer, but physically contacts from SIM to eSIM are not automatically copied during the chip change process).
On your iPhone, go to Settings → Contacts and find the "Import SIM contacts" button at the bottom. The system reads data from the chip and saves it to the device’s memory. This may take from a few seconds to a couple of minutes.
⚠️ Attention: SIM cards have very limited memory and often truncate long names or do not support Cyrillic in older formats. In addition, you cannot store more than one number per contact on your SIM card. Use this method only as a last resort.
For owners iPhone 15 Pro Maxwho are switching to eSIM technology, this method may not be available in the classic form, since the physical chip from the Android phone may not fit in size (Nano-SIM vs eSIM) or simply be absent. In this case, it is better to use the software methods described above.
- 📉 Low quality of transferred data (only name and number).
- ❌ Lack of support for additional fields (addresses, social networks).
- 💾 Risk of data loss if the chip is damaged.
- 🐢 Slow speed with a large number of records.
Is it possible to transfer contacts from SIM to eSIM directly?
No, eSIM technology does not have its own memory for storing contacts in the same way that physical cards do. Contacts are always stored in the phone memory or in the cloud. When activating eSIM contacts are not transferred automatically; they must be imported from a file or the cloud in advance.
Solving problems and duplicates
After data transfer, users often encounter the problem of duplicates. This happens when the same contact is saved in the phone memory, on the SIM card, and in the Google account, and when imported, all these copies end up in the iPhone. Luckily, iOS knows how to deal with this.
If you see duplicate entries, open the Contacts app on your iPhone. The system itself can offer “Duplicates found” and a “Merge” button. If the automation does not work, you can use third-party applications from the App Store or clear duplicates through the web version of iCloud on your computer.
Another common problem is the lack of contact photos. When transferring via vCard or SIM cards, images are often lost. When using Move to iOS or Google synchronization, photos should be transferred if they were linked to a Google Photos account or saved in a contact's profile.
| Problem | Probable cause | Solution |
|---|---|---|
| Contacts are not visible | Synchronization is disabled | Settings → Contacts → Accounts → On. toggle switch |
| Kryakozyabry instead of names | VCard encoding error | Import via Google Contacts (web version) |
| No photo | Limitation method | Use Move to iOS or Google synchronization |
| Duplicate numbers | Multiple import | Use the "Link contacts" function or delete unnecessary ones |
It is also worth mentioning the compatibility of number formats. Sometimes numbers can be written without a country code (for example, +7 or +380), which can cause problems with identifying the number in instant messengers like WhatsApp or Viber. Check the recording format and, if necessary, edit several key contacts manually.
To mass edit numbers (adding a country code), it is most convenient to use a computer. Go to iCloud.com, open Contacts, select the ones you need and edit, or use Google Contacts to batch change.
Frequently asked questions (FAQ)
Will contacts on Android be erased after transferring to iPhone?
No, when using the Move to iOS, Google methods Sync or vCard data on the original Android device remains unchanged. The transfer process works on the principle of copying rather than cutting. However, if you decide to sell your phone, be sure to perform a Factory Reset to remove personal data.
Is it possible to transfer contacts if the iPhone is already set up and in use?
Yes, you can. The method with a Google account (synchronization) and the method with a vCard file work on an already configured phone. The Move to iOS method requires resetting the iPhone to factory settings, since it only works at the initial activation stage ("Hello" / "Hello" screen).
What should you do if the contacts were transferred, but without names (only numbers)?
Most likely, the encoding failed during export or synchronization or the fields were mixed up. Try importing contacts first into the Google Contacts web interface (contacts.google.com), you can often correct the display of fields there, and then synchronize your iPhone with this account again.
Are contacts from WhatsApp transferred separately?
Whatsapp contacts are the contacts in your phone book. If you transferred your main phone book using any of the described methods, WhatsApp on iPhone will see them automatically after installing the application and logging into the same account. There is no need to transfer them separately.
Is it safe to use third-party applications for transfer?
Official methods (Move to iOS, Google Sync) are the most secure. Third-party apps from stores may require access to your personal data. If you are using an unknown application, be sure to delete it and revoke access in your Google account security settings after the transfer is complete.
