The Wireless Messaging API 2.0 (WMA) enables the sending of SMS and MMS messages (MMS was first implemented in S60 3rd Edition).
Verify that the MIDlet successfully sends the SMS message. Make sure that the application gives the user an accurate and appropriate error message if the mobile device is unable to send the SMS message because of external factors (for example, network connectivity).
Check that the message is formatted appropriately if it is sent to the mobile device’s mailbox. If the message is sent to an application, verify also that the SMS message is received and processed correctly by the receiving application.
Check that:
The MIDlet sends SMS messages correctly.
The user gets a clear error message if something goes wrong.
The application sends and/or receives data packets properly.
The message has an appropriate format and it is received and processed correctly by the application.
