International Calls Bolt-On: on one phone?

[BigMatt]

Hello!

I've been with O2 for a year or so (SIM only), adding on family members throughout the year, but this is my first time writing in the community. 

I currently pay for the International Calls Bolt On, it shows under the monthly extras on my PDF bill as I call home a good bit. I know it applies to my phone, but since I have family on my plan now, does it also apply to them? It doesn't show on the bill, and I wanted to check before I gave the OK for them to do it too. 

Thank you!

No, it only applies to the number it is assigned to, it does not apply to any other number on the account.
