Chat and instant messaging apps are among the most commonly installed apps on Android phones. These apps are essential because they help us stay connected and communicate with others.

WhatsApp remains the most popular messaging app today, especially among Android users. But did you know there are many other messaging apps out there with features that go beyond what WhatsApp offers?

In this article, we’ll walk through 10 of the best instant messaging apps for Android besides WhatsApp. You might just find one that’s a perfect fit for you.

1. Google Messages (RCS)

Google Messages is the default messaging app pre-installed on most modern Android phones. It’s primarily used for sending and receiving SMS and MMS.

However, once you enable Rich Communication Services (RCS), Google Messages transforms into a full-featured chat app. If you’re not familiar with it, think of RCS as Android’s answer to iPhone’s iMessage. You can message anyone who also has RCS enabled on their device using an internet connection instead of your phone credit.

Messages sent through RCS are also far more versatile than standard SMS, letting you share images, videos, files, and more.

2. Signal

Of all the apps on this list, Signal is arguably the simplest. By “simple,” we mean it’s built specifically for messaging between Signal users, much like WhatsApp was in its early days.

The app lets users send text messages and make voice and video calls for free, all protected by end-to-end encryption, meaning only the sender and recipient can read the messages.

Signal also offers a range of security features that make it especially popular among privacy-conscious users. It doesn’t collect personal user data and doesn’t display ads.

One key difference between Signal and WhatsApp is that Signal doesn’t collect metadata such as contacts, groups, activity times, or device information. WhatsApp, on the other hand, collects all of this data and feeds it into Meta’s advertising ecosystem.

3. Telegram

Chances are, you’re already familiar with this one. Telegram stands out thanks to several features widely considered better than what WhatsApp offers.

First, there’s the supergroup feature, which allows a single group to hold up to 200,000 members — far more than WhatsApp’s group limit of 1,024 members.

Another feature users love is unlimited file uploads. Free users can upload files up to 2GB each, with no limit on the total number of files. Many people even use this feature as personal cloud storage, creating a private channel and uploading files there for safekeeping.

4. Microsoft Teams

Microsoft Teams is a collaboration app designed specifically to streamline communication and teamwork. It offers features like instant messaging, audio and video calls, and document collaboration tools.

Its standout feature is the ability to create dedicated team chat spaces tailored to specific projects or teams. This allows teams to communicate and collaborate in real time while keeping a record of conversations for future reference.

5. Session

One of Session’s defining features is that it doesn’t require a phone number. Unlike Signal or WhatsApp, Session generates a Session ID — a string of random characters that serves as your identity on the platform.

This means you can chat with anyone without ever sharing your phone number. Session also doesn’t rely on a single central server. Instead, messages are routed through a network of decentralized nodes, a concept similar to onion routing used by TOR. In other words, messages are extremely difficult to trace, making it hard to determine who’s talking to whom.

6. Line

Line is one of the messaging apps that has stood the test of time, with a user base largely made up of younger audiences. Its features are built around the way younger users like to chat.

Stickers are one of Line’s signature features, now widely adopted by nearly every other chat app. Line also has a timeline feature similar to social media, helping users feel more connected to one another.

Line is also known for its stable call quality, even on weaker internet connections — a big reason for its popularity across Asia, including Indonesia and Japan.

7. Wire

Beyond its strong security, Wire also offers a range of collaboration features, including high-quality voice and video calls, easy file sharing, and group chats supporting up to 128 members.

Wire also integrates with other apps like Dropbox and YouTube, and it’s available across multiple platforms, including Windows, macOS, iOS, and Android.

Overall, Wire is a highly secure and feature-rich messaging app, well-suited for users who prioritize privacy and security.

8. Discord

Discord is a popular instant messaging app built specifically for gamers. It allows users to communicate in real time with other members, as well as share files and images.

Its most distinctive feature is the “server,” which lets users create and join communities based on shared interests or specific games.

Within a server, users can interact through text, voice, or video channels, and join voice channels to game together in real time.

9. Threema

Threema doesn’t require a phone number to sign up, allowing users to stay anonymous. It also doesn’t collect personal user data, giving users peace of mind while communicating.

Threema comes packed with advanced features, including scheduled message sending, permanent message deletion on both ends of a conversation, and group chats supporting up to 256 members.

The app is available across multiple platforms, including Android, iOS, and Windows.

10. Viber Messenger

Viber offers a wide range of stickers and emojis, letting users express themselves in a more creative and playful way. Users can also customize themes and wallpapers to personalize the app’s appearance.

Viber also comes with strong security features, including end-to-end encryption for messages and voice or video calls, along with easy-to-manage privacy settings.

If you’re looking for an alternative messaging app that’s both easy to use and widely popular, Viber is a solid option worth trying.
