If you’re encountering a file size restriction on your Android device, there’s a simple workaround: enable Rich Communication Services (RCS). This messaging feature for Android is akin to the iMessage app on iPhones. Instead of using SMS/MMS, RCS uses Wi-Fi to bypass the mobile provider. However, RCS may not be available on older Android phones or with carriers that do not support it. Currently, only a few texting apps support RCS.

To enable RCS in Google Messages, follow these steps:

1. Open the Google Messages app or download it from the Google Play Store if you don’t have it.
2. Tap the user icon in the top right corner.
3. Select Messages Settings from the drop-down menu.
4. Tap the RCS Chats option (listed as Chat Features on some phones).
5. Toggle on the RCS Chats setting.

If you have a Galaxy smartphone, you can use RCS messaging in Samsung Messages, but the process is a bit more complicated. First, ensure that your carrier supports the advanced messaging feature (RCS) in the Samsung app. To check if it’s enabled:

1. Open the Samsung Messages app.
2. Tap the three vertical dots.
3. Tap Settings.
4. Look for Chat Settings — if it’s grayed out, it means your carrier doesn’t support RCS in the Samsung app. If it’s not grayed out, RCS is available in Samsung Messages.

By activating RCS, you’ll be able to send files with a file size of up to 100 MB. However, for RCS to work properly, both you and the recipient need to have the feature enabled. Additionally, you might need to disable your phone’s built-in power-saving feature for RCS to function smoothly.
