GSM OPERATORS’ ROLE IN PARTIAL DELIVERY OF BULK SMS
One thing of note while sending messages is that it is the GSM operators that handle the delivery of messages. And for a message to get delivered to a particular phone number or not, it is a factor of the GSM operators and the recipient’s phone line itself.
Each GSM operator has different stance concerning word in content of message and sender IDs that are acceptable and the ones that are not.
Generally, GSM operators have a filtering system which contains list of words that are not allowed either as sender IDs or in the content of a message. This list is not the same for all GSM providers. This explains why sometimes, a message might deliver to a particular network but will not to another. For example, a sent bulk SMS might get delivered to GLO numbers but MTN lines will not get it, because there is something in the content of the message that MTN do not allow.
The GSM operators might also reject a message. This might be because the phone number the message is being sent to has been blocked from receiving messages or the message sent is seen as a spam(randomly unsolicited) and so the network operator rejects it.
Another possible reason for partial delivery of bulk SMS might be as a result of an error from the GSM operator’s server. If this error occurs during the time the message was meant to get delivered, the delivery to that particular network might fail whereas other phone numbers gets delivered.
On SmartSMSSolutions though, you do not have to guess to know how many of your recipients got the message you forwarded to them. You can check the delivery report for your sent messages to know this. Additionally, we’ve put together a list of delivery status codes and what they mean so that you can tell where the partial delivery of your sent messages is coming from.
