How to Send an SMS to Myself

Question

How can I send an SMS to myself on Android? I want to enter a sender and fictitious content, and have it appear in the SMS notifications bar.

Answer 1

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("DESTINATION NUMBER", null, "Your Message Text", null, null);

Also in your Android Manifest file, add the following permission:

uses-permission android:name="android.permission.SEND_SMS"

Or if you would like to send a SMS with more than 160 characters:

String phoneNo = "INSERT NR HERE";
String message = "This is a long message that is supposed to be longer than 160 characters.";

SmsManager smsManager = SmsManager.getDefault();
ArrayList msgparts = smsManager.divideMessage(message);

smsManager.sendMultipartTextMessage(phoneNo, null, msgparts, null, null);
