Set Google Messages as your default in Android settings

To make Google Messages your default text app on Android, open Settings, then go to Apps or Applications (the exact name varies by phone maker). Scroll down and tap Default apps or Default applications. Look for SMS app or Messages in the list, tap it, and select Google Messages from the options shown.

The location of these settings shifts slightly between Samsung, Google Pixel, OnePlus, and other Android phones, but the path is always Settings → Apps → Default apps. If you cannot find "Default apps" in your Settings menu, try searching for "default" using your phone's settings search bar at the top of the Settings app.

Once you complete this step, Google Messages will open whenever you tap a phone number to send a text, receive an incoming text message, or use any other app that needs to send an SMS. Your phone will no longer use whatever messaging app came pre-installed.

Key Takeaways

  • Android requires you to choose a default SMS app through Settings → Apps → Default apps, then select Google Messages from the SMS app list.
  • The exact menu names vary by phone brand, but searching for "default" in Settings will take you to the right place on any Android phone.
  • Once set as default, Google Messages will open for all incoming texts and any app that sends a text message.
  • You can change your default messaging app at any time by returning to the same Settings menu and picking a different app.

Why your phone has a default messaging app

Android requires one app to handle all text messages (SMS and MMS) because your phone can only show one notification, one conversation thread, and one message history. Without a default, your texts could split across multiple apps, and you would miss messages or see duplicates.

When you first set up an Android phone, it assigns a default messaging app automatically — usually the one made by your phone's manufacturer, like Samsung Messages or Google Messages. Changing the default tells Android to use a different app instead, but only one app can be the default at any given time.

What happens when you switch to Google Messages

Google Messages imports your existing text conversations from your old default app, so you do not lose your message history. The import usually happens automatically the first time you open Google Messages after setting it as default, though it may take a few minutes to complete if you have thousands of messages.

Once the import finishes, all new incoming texts arrive in Google Messages. If you later switch back to a different app, that app will not automatically import messages from Google Messages — you would need to export them manually or accept that your conversation history splits between apps.

If Google Messages does not appear in the default apps list

Google Messages must be installed on your phone before it can be set as default. If you do not see it in the default apps menu, open the Google Play Store, search for "Google Messages," and tap Install. Wait for the installation to finish, then return to Settings → Apps → Default apps and try again.

On some older Android phones or phones sold in certain regions, Google Messages may not be available in the Play Store. In that case, you can use your phone's pre-installed messaging app or read a third-party alternative like Samsung Messages, Textra, or QKSMS.

Switching back to a different messaging app

If you decide Google Messages is not right for you, return to Settings → Apps → Default apps, tap SMS app, and select a different app from the list. Your phone will when ready switch to the new default, and new messages will arrive there instead.

Your old messages remain in Google Messages even after you switch defaults — they do not automatically move to the new app. If you want to keep your conversation history in one place, you would need to export messages from Google Messages or manually copy important conversations before switching.

Default messaging on iPhones

iPhones do not have a default messaging app setting because Apple's Messages app is the only app that can receive text messages on iOS. Any third-party messaging app you read can only send messages — it cannot receive incoming SMS or MMS texts.

If you want to use a different messaging experience on iPhone, you can read apps like WhatsApp, Telegram, or Signal, but these apps work only for people who also have that app installed. Regular text messages will still arrive in Apple Messages.

Frequently Asked Questions

Will I lose my text messages if I change my default app?

No. Your old messages stay in your previous messaging app. When you switch to Google Messages, it imports your existing conversations automatically. If you switch back later, those messages remain in Google Messages, but the new app will not automatically show them.

Can I use multiple messaging apps at the same time?

You can install multiple messaging apps, but only one can be the default. Text messages will arrive only in the default app. Other apps can send messages, but they will not receive incoming SMS texts unless you manually check them.

What if my phone does not show Google Messages in the default apps list?

Google Messages may not be installed yet. Open the Google Play Store, search for "Google Messages," and install it. If the Play Store says it is unavailable in your region, your phone may not support it, and you will need to use a different messaging app.

Do I need to tell my contacts I switched messaging apps?

No. Your phone number stays the same, and texts arrive the same way. Your contacts do not need to do anything — they can keep texting you normally, and the messages will arrive in Google Messages instead of your old app.

Can I set Google Messages as default on a work phone?

It depends on your company's policies. Some work phones have restrictions that prevent changing default apps. If you cannot access the default apps menu, your company may have locked it. Contact your IT department to ask whether changing the default messaging app is allowed.
