I have just upgraded and have my new phone but I have no welcome email or confirmation to screenshot and send. I changed my email from an old one that I have no access to and think perhaps the invoice and welcome email went to that email.

I have looked at my plan on my ID mobile account but can't find anything useful and can't find a copy of the invoice. I only chose this phone as I also needed a tablet and I dont know how to redeem it.

Any help would be welcomed. Thank you
