Unable to SSH using Putty remotely (different country)

I have Debian installed in embedded PC which is in a vehicle . This PC collects information related to engine .This pc is connected to internet using Verizon USB 175 modem.i connect to internet uing Wvdial. On connection it gets dynamic IP and uing this Ip i planned to login through Putty.

This whole system Is in US , when i was in US i had laptop which is connected to internet using verizonPCMCI modem. from that laptop i used putty and entered dynamic ip in Putty and i could successfuly login to the system in vehicle.

But when i came back to India i tried to login to the system , here i have different ISP not verizon , i tried to ping that IP ( technician called from US and informed the new IP ) in the Vehicle and i was successful in doing that , i got echo to my ping. Now using that Ip in putty to login but i could not login ,it gives time out .

Can some one please let me know wat is the real problem.
is it verizon blocking the SSH port from outside ?

It is mostly a port block issue., Like Please suggested , contact your ISP
If you are using a different laptop here , try disabling the firewall.

You can use the telnet client to check whether you can connect to port 22.
 telnet hpmedia 22
Connected to hpmedia.
Escape character is '^]'.
You don't get any further than that, of course. But this is an easy way to check if you can access a certain port.

Initially i thought its problem with indian ISP , than i asked one of my friend in Hungary to login to the system using putty and he faced the same problem ,he could ping but cannot login.

Even i did other expirement , i have debian installed in my laptop connected to internet than i used website based shell program to login to my laptop , and i could succesfully logged in this shoes that my ISP provider is not blocking port 22
