So, I now have 2 sims. One for me and now one for the missus. I look after both accounts and that has highlighted an issue.
On the emails you send, would it be possible to put the phone number that email refers to? Just the last 3 numbers would be fine if it's a security thing, plus, can this be added to the account page when you're logged in? (I've been known to log out to see which one I'm looking at)!!
