Any idea please?

Thank you!!!

Are you sure about those phone numbers, whether they are correct and presented in international format?

You could put the SIM into your handset, and try if sending works with it. Then check what is the correct number of SMSC (Service Center). If it's stored into SIM, it's not needed to define it in smsd.conf. In any case, number for smsc setting is not a SIM's own number.


In the setup there are another things too:

Setting for eventhandler should be single executable. Use eventhandler = /var/smstools3/scripts/eventhandler and start the file like:

#!/usr/bin/php
<?php

See this post for some details.

A setting init = AT+CMGF=1 is not required, and it overrides the previous setting. Just remove it.

You was right, the SMSC (Service Center) number was wrong!!.. corrected and all works OK!!!. The phone was new, but it comes programmed incorrectly. Other corrections also worked well.
Another problem, some times, the received message text appear with strange characters:
�M�e�n� �c�o�l�a

Any ideas?

Thank You!!!

Use a global setting decode_unicode_text = yes.

Thanks for your reply. The problem still occurs when using accented letters such as "á", "é", "ñ", etc. (Spanish language characters).

Thank You!!!

Assuming that the locale in your server is UTF-8, use a global setting incoming_utf8 = yes.
