Rocket IPTV Routes?

Help for Rocket IPTV Server.
Rocket and NFPS name their 'codes' as 'Donations', or sometimes as 'User ID'
While iptv66 name their codes as 'Routes' ... I guess to keep with the theme of 'Route 66' , which is a famous road or highway found in the USA
 
I am not really sure what you are asking.

One 'code' is good for one user and one device .
If there needs to be two devices (two users), then you would need a second code.
A code is a username and password. The username and password are the same 12 or 13 digit number.
This is called a Donation number or a Route number (depending where you get it from).

IPTV66 may have a working trial ,but it may not be working either, I do not know. They do have a one month sub too thou.
But check the website linked below, to see what they offer.
If you are gonna use the trial, ensure that you are setup with before you carry thru because the trial may only last a couple hours weather it is used or not.

IPTV66 Donation codes are called 'Routes'
