Can Android App Send SMS?

Android, Android Apps

Are you wondering if Android apps are capable of sending SMS? The answer is a resounding yes!

In fact, it’s one of the most common features included in Android apps. This article will give you a comprehensive overview of how Android apps can send SMS and why it’s important.

How Do Android Apps Send SMS?

Android apps can send SMS using the SMS Manager API. This API allows developers to create and send SMS messages directly from their app.

The process involves creating an instance of the SmsManager class and calling its sendTextMessage method. Here’s an example code snippet:

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, message, null, null);

In this code snippet, “phoneNumber” is the recipient’s phone number, “message” is the text message to be sent, and the last two parameters are used for delivery reports and sent message callbacks respectively.

Why Should Android Apps be Able to Send SMS?

There are several reasons why it’s important for Android apps to be able to send SMS messages.

Authentication Purposes

Some services require that you verify your account through a phone number. In such cases, the app needs to send an SMS with a verification code for authentication purposes.

Notifications and Alerts

Apps may also need to notify users about events or alerts through text messages. For example, a fitness app may remind users about their workout schedule or a banking app may notify users about suspicious transactions on their account.

Social Networking

Social networking apps like Facebook or WhatsApp use SMS for user verification and contact discovery purposes.


In conclusion, Android apps are definitely capable of sending SMS messages using the built-in SmsManager API. The ability to send SMS messages is crucial for many apps, especially those that require authentication or need to send notifications and alerts. If you’re a developer, make sure to take advantage of this feature in your next Android app project.
