A lot of thanks Mykola, I tried to:
- Find the nano3G ip address, I found it and create a rule in my dhcp
server to assign a fixed ip address.
- Ping the nano3G: 0% packet loss.
- Scan all TCP ports with nmap: there is no open port
- Capture all network traffic from nano3Gwith tcpdump: it connect to a
T-mobile to perform a isakmp handshake without any result, also get the
date and time from some ntp servers.
- Perform a factory reset but I think that this action just restore the
custom operator firmware, at this step the nano3g also connect to ip.access
servers and download some crl certificates, then also try the isakmp
handshake with T-mobile server.
Best regards

Good day, Ernesto
it seem to have a custom firmware for an
operator that does not work in
my country
How have you found that out? What actions have you taken? Have you
performed a factory reset?
If you expand on the description of your problem, then it will be much
easier for someone here to help you.
With best wishes, Mykola
