So I have the 2024 BYOD plan with the $55/mo plan discounted to just $15/mo per line with 2 lines, so a total bill of $30/mo. I recently had to activate a new sim for one of the lines and asked CS at the time if I can add more lines for the same price, and they said yes after checking something for a moment, but I'm just wondering if anyone has confirmation of this working.

So, anyone else have done this where they add a line and a) keep the current discount and b) the new line has the same discount? Was it an easy process to add lines, with or without porting in numbers?
