I recently purchased an upgrade for my son and because ID mobile couldn't originally match my other option they instead offered an upgrade of unlimited data despite the contract being 10GB which I accepted. However the app is still showing 10GB and not unlimited. There is roll over data from the previous contract. Will this rectify itself next month or will the roll over expire and he will be left with only 10GB? I was told the unlimited data would last 24 months. This was done via phone and I have no email confirmation other than the contract agreement which states 10GB.
