Good day, Miguel. My name is Jessica_ST and I'll be addressing your concern. You will just need to delete older text messages to be able to send and receive text messages from/to your phone again. To delete a message or message thread, go to Messaging Menu < From the message lists, touch and hold the message thread to display the context menu < Tap Delete thread and once prompted, tap OK to complete the process. You may also adjust your message settings so you will not encounter the same message again. From the Main screen, go to Messaging Menu < From within the Messaging screen, press the Home key and tap Settings < Adjust the following settings according to your needs: a) Delete old messages Enable this option to delete older text messages when the limit for maximum number of text messages is exceeded; b) Text message limit Sets the maximum number of text messages that can be stored on the device (per conversation). We hope this helps. Thank you.
