Q5100090: I want to send SMS messages to my recipients, but I don't want the GSM telephone number be displayed on their mobile phones. Instead, the name of our company should be displayed. Is this possible?
Yes it is possible to use an alphanumeric source address with a maximum length of 11 characters. Such feature can only be used with the SmsProtocolSmpp object or SmsProtocolHttp object, not with the SmsProtocolGsm object. Gsm modems/providers simple don't support this feature.

Q5100130: When i send an MMS to a particular phone, the MMS isn't downloaded but an SMS message with a link on the web is displayed. What can be the problem ?
Most probably, the phone you are sending the message to is never used to send MMS messages before. In order to receive an MMS message on a phone, you have to send an MMS message first (one time only).

This depends on the provider you are using and the provider of the receiving party. Most providers support messages up to 200 Kbytes.

This is very easy. You can check this by checking the 'Format' property of the 'SmsMessage' object.

If ( objMessage = objConstants.asMESSAGEFORMAT_UNICODE ) Then ' Message is unicode End If If ( objMessage = objConstants.asMESSAGEFORMAT_TEXT ) Then ' Message is text End If

Q5100320: How can i determine the carrier of the originating number of a received SMS ?
To find the carrier associated with a mobile number, you have to perform a so called HLR lookup. Some providers offer this service, which can be accessed by sending HTTP GET or POST queries. This functionality is not offered by the SMS and MMS toolkit itself, but can be easily implemented by using the ActiveXperts Network Component.
