New contract

Hi. I pay for a monthly SIM here for my son. I have to say it’s so good I’d like to change my contract over too!
Is it possible to have two lines on one bill? And is it possible to end the monthly one and pay for both annually going forward?

thanks in advance, Marty

MartinS18 yes you can manage multiple SIMs on under account. If you want to be the man account holder I would suggest getting yourself setup then bringing your sons number into your account. Regarding paying annually thats not currently an option.
