Mobile Phone Ultimate Subscription advice

I have 2 mobiles. One for my every day use (Business) and my Wifi only phone for all the apps i like using which is connected to my Tv. If i add the ultimate subscription on my 1 mobile is it also free to use on my other mobile? so basically i have it on both my phones?

Hi, yes, you do. On the other device just use the activation code you got when purchasing the licence for your first device.
