First steps

Before you get started, you should make a few preparations. This will help you avoid trouble and save time.

Preparing for setup

• Back up old phone: Check that all important data—such as contacts, photos, videos, SMS, and app data—are saved. Use cloud services like Google Drive (for Android) or iCloud (for iPhone).
• Passwords and logins: Make sure you have all login details ready, especially for Google, Apple, email accounts, and social media apps.
• Update apps: Ensure your old phone is up to date and all apps are updated. This will make data transfer easier.
• Enable backup: On Android, you can create a backup under “System” > “Backup” in the settings. On iOS, this happens automatically via iCloud.
  
  

Securing apps and logins

Apps are the heart of your smartphone. To avoid starting from scratch, make sure your apps and their data are backed up.

• Many apps automatically store data in the cloud (WhatsApp, Facebook, Google Photos). Check this in each app’s settings.
• Some apps offer their own backup features. You should use them to save chats or game progress.
• Write down important passwords or use a password manager.

If you follow these steps, you can set up your new phone with Google and gain direct access to your usual apps and data.

Inserting the SIM card

The SIM card is your access to the mobile network. Without it, you can't make calls, send SMS, or use mobile data.

Reusing your old SIM card

If you want to set up your new phone using your old SIM card, keep in mind:

• Check whether the SIM card is in the correct format (nano, micro, standard). If needed, you can trim it with a SIM cutter.
• Carefully insert the SIM card into the SIM slot. Most modern smartphones have a small tray that you open with a SIM eject tool.
• If your new phone supports eSIM, you may be able to replace the physical card. Your mobile provider will give you a QR code for activation.

Solving SIM issues

If your phone doesn't recognize the SIM card:

• Check whether the SIM is inserted correctly.
• Test the SIM card in another phone.
• Contact your mobile provider if the SIM might be defective.
  
  

Safely transferring all content to the new device

Transferring your data from the old phone to the new one is one of the most important steps. This way, you won’t lose any valuable memories or contacts.

Transferring data on Android devices

For most Android phones, data transfer is now very convenient:

• When you first turn on your new phone, you’ll be asked whether you want to transfer data from an old device.
• You can connect the devices via USB cable or sync them over Wi-Fi. For Samsung users, we recommend the Smart Switch app, which also simplifies transferring data from an iPhone.
• Sign in with your Google account to transfer apps, passwords, contacts, and settings.
• Choose which data you want to transfer—e.g. photos, messages, contacts, apps.

The process can take anywhere from a few minutes to over an hour, depending on the amount of data.

Transferring data on iPhones

• Activate the Quick Start feature on your new iPhone by placing it near your old iPhone.
• Follow the on-screen instructions to pair the new device with the old one.
• Alternatively, you can use an iCloud backup to load all content onto the new iPhone.
  
  

Switching from Android to iPhone

• Use the Move to iOS app on your Android phone, available for free in the Google Play Store.
• The app helps you securely transfer contacts, messages, photos, videos, and bookmarks to your iPhone.
  
  

Adding and setting up a Google account

The Google account is the center of your Android experience:

• It gives you access to the Google Play Store for downloading apps.
• It backs up your contacts, calendar, and photos to the cloud.
• It protects your device with the “Find My Device” feature.
  
  

Setting up a new phone with Google

• During the initial setup, you’ll be prompted to sign in with your Google account.
• If you don’t have one yet, you can create a new account directly on the phone.
• Make sure you use the correct email address and password to avoid issues later on.
  
  

Special tips for Samsung phones

Samsung users benefit from exclusive features:

• The Smart Switch app allows for very easy data transfer from almost any smartphone, whether Android or iPhone.
• Samsung accounts also sync contacts, calendars, and settings.
• Samsung offers its own cloud services, which can be used alongside your Google account.
• If you run into problems, the Samsung Members app provides support and helpful tips.
  
  

FAQ – frequently asked questions

Can I set up the new phone without a SIM card?

Yes, that’s possible. Many features like Wi-Fi, apps, and the camera can be used without a SIM card. However, calling or using mobile data won’t work.

What should I do if my Google account isn’t accepted?

• Check your internet connection.
• Make sure the login credentials you entered are correct.
• Reset your Google password if necessary.
  
  

How long does the data transfer take?

That depends on the amount of data. Small backups take just a few minutes, while large photo and video collections can take several hours.

All set to get started!

Once the SIM card is inserted, the data transferred, and your Google account is active, nothing stands in the way of your new phone. Don’t forget to install your most important apps, store your passwords securely, and make regular backups. That way, you’ll be fully prepared and can enjoy your new smartphone to the fullest!
