if the sms_api.php is running on my home apache-server, the sms messages will be sent immediately. But on a paid hoster environment (..supports php) the call of the sms_api.php takes no effect. I dont get any message on my mobile phone.
Where is the problem?
thanks in advance
It's possible your hosted environment doesn't support fopen calls (these days, most don't). Try to change sms_api.php to use "curl" calls instead.
Are you able to take a look at your hosted environment's logs? They might give you a clue about what is failing.
