How to receive a SMS message?

The incoming SMS message is being delivered as same as any ordinary e-mail, in the Sender field can be seen the SMS address of the sender, so you can Reply as usual (Reply).

How to check, whether our SMS has been sent?

As soon as MobilChange sends a message to GSM network, it delivers a sending confirmation to the user, which contains the exact copy of sent text, just to verify, that MobilChange sent the SMS correctly.

(Non)Delivery confirmation report.

MobilChange delivers confirmation about delivery (not-delivered) if the GSM operator supports this service. The selection to demand or not can be set at "Sending option".

Send options

The user can set up or infuence how will be his SMS sent. With help of "@ commands". These commands must be written at the beginning of the message, one command per line. Between the last @command and first line of the main message text must be enpty line.

Allowed @commands:

(Not)delivered confirmation setting
Action - how MobilChange handles with the message
Message format changing

(Not)delivered confirmation setting

If you write @dr=1 or @report, you demand confirmation that your SMS has been successfully delivered to the targeted cell phone. (if supported by GSM operator)

If you write @dr=0, you say you DO NOT want the confirmation.

If you write nothing at the message beginning, it is used the system setting - demanding delivery confirmation.

Action - how MobilChange handles with the message

With the command @action=... you set, how will be the outgoing message handled or proceeded by MobilChange. If no choice is selected, the message is being sent (as same as the first selection - Send).

@action=0 - The message is being sent. If the text of the message is longer than the maximum of SMS message length, the message is going to be divided to more pieces. In the case that the number of SMS messages which was created by dividing the long one, is bigger than the limit set by the administrator, the message is being cut.
@action=1 - The SMS is being sent only if the number of messages, to which is the outgoing message divided, shorter than the limit set by the administrator. If the message is longer, it is not being sent and MobilChange sends a warning message to the sender that his message has not been sent.
@action=2 - SMS is being sent only if the outgoing message is divided into the max. count of messages that is set by the command @maxlen=#. The set limit is subordinate to the limit defined by the administrator, the behavior by the overcame limit is the same like by "system limit".
On next line behind the command @action=2 must follow the command @maxlen=#, where instead of # is max. count of SMS from one e-mail address.
@action=3 - SMS is not being sent, the sender receives from MobilChange a message where is seen the format, in which the message would have been sent (headers, separated SMS dividing ...)
Instead of this command you can type @preview

SMS messages format

Sent SMS usually is updated of sender's email address, the summary count of messages to which was the first divided etc. -- looks like this:

1/3 F:brouzda@datasys.cz S:problem-Rychle mi zavolej,mame...

If you do not want the additional headers, you must write to the beginning of the message this command:

@nomodify

Notification about incoming e-mails

You can use notification about incoming e-mails by SMS. So if you receive e-mail, Mobilchange can send informative text message to your mobile phone about it.
This function is turned on by this procedure: set all mail autoforwarding "as an attachment" to "notify.xxx@sms" (or "notify.xxx@sms.sms") address. All forwarded e-mails will be trimmed to one SMS length and sent to "xxx" number.

How to set up autoforward? It is very dependent on your mail client. E.g. mailers on Unix/Linux searches your home directory for ".forward" file and according its content processes incoming messages. Look for more information in documentation for your mail client or ask your mail system administrator.

SMTP receiver is required for this feature - it doesn't work with normal SMTP/POP3 gateway.
