Changing the ecosystem from Android to iOS is always stressful due to the risk of losing important data. Users are most concerned about the safety of their phone book and correspondence history, since this is the basis of communication. Modern migration methods allow you to transfer contacts and SMS from Android to iPhone with virtually no user intervention, but require strict adherence to the sequence of actions.
The main tool for this task is the official application Move to iOSdeveloped by Apple specifically for such cases. It ensures the creation of a secure communication channel between devices and transfers data directly, bypassing cloud storage. Unlike manual copying, this method guarantees the integrity of the message structure and the correct display of names in contacts.
Before starting the procedure, you must make sure that both devices are charged at least 50-60%. The process can take from 15 minutes to several hours depending on the amount of information transferred. A stable Wi-Fi connection on the receiving device is critical to the successful completion of the migration.
⚠️ Attention: Do not interrupt the data transfer process, even if the device screens go dark. Interruption at the SMS copying stage may damage the message database on the new iPhone, which will require a full reset.
Preparing an Android smartphone for migration
The first step is to carefully prepare the source device. You need to free up memory space by deleting unnecessary applications and cache to speed up the system during transfer. You should also check that data transfer via the mobile network is enabled on your Android device if the Wi-Fi connection is unstable, although it is preferable to use a wireless network.
It is important to update all system components and the application itself Move to iOS to the latest version. Older versions of the software may contain bugs that will cause the process to freeze at the Time Estimation stage. Check your security settings: the screen lock on both devices should be disabled or you should know the passwords, as the system may require confirmation.
- 📲 Remove antivirus and VPN applications, as they may block the local connection between devices.
- 📲 Close all background applications to free up RAM for the migration process.
- 📲 Make sure that geolocation is enabled on your Android smartphone; this is required for some application functions to work.
Particular attention should be paid to your Google account. All contacts must be synced with a Google account before starting the process. This will create a backup in case the automatic transfer does not complete successfully for some reason. You can check synchronization in the section Settings → Accounts → Google.
If you have important SMS in messenger applications (WhatsApp, Viber), use the built-in backup functions inside these applications before switching, since the standard transfer of SMS concerns only the standard Messages application.
Setting up the iPhone and launching the Move to iOS application
The transfer process is possible only during the initial setup of the iPhone. If the device has already been activated and is in use, it will have to be reset to factory settings through the menu Settings → General → Transfer or reset iPhone → Erase content and settings. This is a mandatory iOS security requirement.
After a reset or when turning on a new device, follow the on-screen instructions until the Apps & Data screen appears. This is where you need to select the “Transfer data from Android” option. A six- or ten-digit code will appear on the screen, which will be needed to pair the devices.
On your Android smartphone, launch the application Move to iOS. Accept the terms of the agreement and click "Continue". The system will ask you to enter the code displayed on the iPhone screen. After entering the code, the devices will establish a direct Wi-Fi connection. Don't be alarmed if Android warns you that the network is switching - this is normal behavior.
⚠️ Attention: While data is being transferred, do not switch to other applications on your Android device. Activity in other apps can break the connection or slow down the process indefinitely.
Selecting data for transfer: contacts, messages and media
After a successful connection, the application will prompt you to select the types of data to transfer. The interface on an Android device will allow you to tick the necessary items: contacts, message history, photos and videos, mail accounts and even some free applications available in the App Store.
For our main task - transferring contacts and SMS - you need to make sure that the corresponding switches are activated. The system will automatically calculate the amount of data other than the transfer time. It is worth noting that multimedia messages (MMS) are also transferred along with text messages, preserving attachments.
The table below compares the types of data that can be migrated and those that require manual intervention:
| Type data | Transfer status | Nuances |
|---|---|---|
| Contacts (Google) | Full | Groups and photos of contacts are saved |
| Text SMS | Full | Date and time of sending are saved |
| MMS (photo in SMS) | Full | Attachments are saved in the gallery |
| Call history | Partial | Depends on Android and iOS version |
| Local files | No | Require manual copying |
After selecting the data, the copying process will begin. A loading bar will appear on your iPhone screen and may not move smoothly. This is due to the fact that small text files are transferred first, and then large media archives. Do not touch the devices until a completion message appears.
Solving synchronization problems
Despite the smooth process, users often encounter errors. One of the most common is the message "Failed to transfer data" or a hang during the evaluation phase. Most often this is due to an unstable Wi-Fi signal or interference from security apps.
If the process is interrupted, it is recommended to restart both devices and try again. Before relaunching, make sure that Android's power saving mode is turned off, which may limit background app activity. Move to iOS. Also try turning off the mobile data on your Android smartphone, leaving only Wi-Fi.
- 🔄 "Low memory" error: free up space on your iPhone by deleting unnecessary system files or photos.
- 🔄 Connection error: make sure "Private DNS network" mode or similar functions are not enabled on Android privacy.
- 🔄 Process freeze: force close the app on Android and start it again without resetting the iPhone.
What to do if SMS have not been transferred?
If contacts have been transferred but no SMS, they may be stored on the SIM card. Remove the SIM from Android, insert into iPhone (if the form factors are the same) or use an adapter, then select "Import contacts from SIM" in iPhone settings. However, the correspondence history is stored in the phone's memory, and not on the SIM card.
Alternative methods for transferring contacts
If using the official application is not possible, there are alternative methods. The most reliable of them is synchronization through a Google account. Since Android contacts are saved to Google Contacts by default, it's easy to get them on iPhone.
To do this on iPhone, go to Settings → Contacts → Accounts → Add account. Select Google and enter your account information. In the list of synchronization services, be sure to activate the "Contacts" toggle switch. In a few minutes, the numbers will appear in the iOS phone book.
Another option is to use a VCard file. On Android, export contacts to a .vcf file through the Contacts application, send the file to yourself by email or messenger. When you open this file on your iPhone, the system will prompt you to add all the numbers it contains. This method is good for a one-time transfer, but is not suitable for SMS.
Synchronization through a Google account is the fastest way to transfer only contacts, but it is absolutely powerless with respect to the history of SMS correspondence.
Completing the migration and checking the data
After the scale on the iPhone is full, the system will prompt you to complete the setup. Don't rush to go to your desktop. Give the device a few minutes to run in the background to index the received data. Contacts may appear in the list gradually, as they are loaded from servers or from local storage.
Check the integrity of the data. Open the Messages app and make sure your conversation history is displayed correctly, with no missing dates. Go to the Contacts application and check whether the names of the subscribers are identified correctly, and not just phone numbers.
It is important to understand that some older SMS formats or messages with non-standard encodings may not display correctly. This is rare, but possible when migrating from very old versions of Android. In this case, it is better to save critical messages manually or take screenshots.
⚠️ Attention: After data transfer, two-factor authentication (2FA) in some banking applications or services may require re-configuration, since SMS confirmation codes will be sent to a new device number (if the SIM card has been swapped) or require confirmation through the app.
☑️ Final check after the transfer
Frequently asked questions (FAQ)
Is it possible to transfer SMS without resetting the iPhone?
Unfortunately, the standard method through the Move to iOS application only works during the initial setup stage. If your iPhone is already set up and has data on it, you will have to do a hard reset. Alternative paid PC apps may try to add SMS without resetting, but their reliability is not guaranteed by Apple.
Are messages from WhatsApp and Telegram transferred?
No, standard SMS transfer only applies to the standard Messages application (green bubbles). There is a separate feature for WhatsApp called “Transfer WhatsApp Chats” that appears on the iPhone setup screen. Telegram and Viber store history in the cloud and are restored when you log into your account.
What to do if contacts were transferred with duplicates?
When synchronizing with Google and iCloud, duplicates sometimes occur. On iPhone, you can merge them automatically: go to the Contacts application, click on a group or list, and if the system detects duplicates, it will offer a “Link” or “Merge Duplicates” button.
How long does it take to transfer 1000 SMS and 500 contacts?
This amount of text data is very small and takes literally 1-3 minutes. Most of the time is usually spent connecting and handshake of devices. If the process lasts longer than 10-15 minutes at this volume, then there is a connection error.
Do you need to remove the SIM card from Android before starting?
No, you do not need to remove the SIM card. Moreover, if you have an iPhone with a physical SIM, you will need the same card (if the form factor is the same) or a new one from your operator to activate iMessage. It is better to move the SIM card to the iPhone after the transfer of data via Wi-Fi is completed, so as not to interrupt the connection.
