I have shared data on my plan - it covers the data usage on two other devices. I use these devices for business and ideally I would prefer to share the data pack across these three devices - just how I do here in Australia.
From what I can see - I can purchase a data pack for my account, but there’s no information that tells me if it will be usable across all of the sims on this account.
If I purchase a data pack, will I be able to use that data on any of my three devices - as there is no option for me to purchase data packs for them individually.
Roaming travel packs only apply to the single service they are activated against, the data is not shared.
