Secondary can be split. That is when you have multi connection, you have same customer ID. When you want to terminate, they will just split it.
Then it's up to us to use it with a dish. When you want it back, just merge it back.
I think it's possible to activate higher pack in secondary connection... May be a bug.
When there was no Infinity Monthly pack, CC was able to activate Jackpot on my secondary connections, which was 777, but Infinity was only 700.
