I want to sniff SMS but in wireshark I just see GSMTAP protocol and gsm_sms filter is empty...
What is the problem?
- Priority changed from Normal to Low
First of all, we don't give any explanations / instructions about sniffing, hijacking, DoSing, and so on. If you really need to understand this for research / education purposes, you're on your own here. Moreover, your question doesn't contain any useful details to answer it. Most likely, your desired SMS is encrypted, thus you won't see anything in Wireshark.
