In our network SMSMO success rate is very poor. We took a NSS side trace and found the following statistics:
Total SMS Attempts 1136
Actually there a reason for Low SMSMO Success rate. There is virus in some handsets which generate spam messages after every 7 seconds to 3396003964. This we saw from trace CDRs.The bad effect is that this attempt is not charged and it results in SD blocking as well on radio side aswell. How to combat it? Any ideas are welcome.
