Hello Luis,
Good day. Thank you for your question.
If you would like to check the IP (domain) and port of the Main Server, kindly send the following SMS command:
With login and password : <login><space><password><space>getparam 2004;2005
Without login and password : <space><space>getparam 2004;2005
If you would like to check the IP (domain) and port of the Second Server, kindly send the following SMS command:
With login and password : <login><space><password><space>getparam 2007;2008
Without login and password : <space><space>getparam 2007;2008
If you are sending via GPRS then you may skip the login, password, and <space>.
Please try this out and let me know if it helps.
Kind regards.
