I have had an ID mobile plan for my son's phone since December and was recieving email bill notifications up until I decided to join id mobile too a few months ago. I have both plans on my id mobile app but only ever receive a bill notification for my bill now not my son's. This is especially frustrating since he failed to tell me he was out of data on holiday and ran up a £112 bill! I have raised it multiple times with ID and still getting no resolution. Yes I know I can look on the app for the bill amount and date but he email notification is there for a reason, to prompt me to look in the app and ID mobiles preferred way of billing.
The email address and settings are correct in the app.
