Hello Experts.
We have a strange network behaviour:
There was a spamming SMS from a certain sender, which we couldn’t find ANY TRACE for that SMS to the other sender from the network.
A sends to B
We could not find any sign for this SMS in all nodes from Core side.
Any idea?
What about CDR?
No records in SMSC / MSC
That’s really strange…
Is it a P2P message or an A2P?
It’s A2P.
Is there any screenshot of SMS you can share?
Just to confirm if it really is SMS, Flash SMS or USSN message.
It’s a text SMS.
It cannot be p2p…
Can be also a P2P. The only difference is that it may not be a true P2P but rather an impersonated one that actually generated from SMPP, simbox or any other system.
There is a fine chance that it’s a bypass case, as per what I’ve experienced till now.
Correct!
It may be impersonated message, but not direct p2p.
