I was previously on a plan with 4gb data, which was made up of 1gb base data and a lifetime triple data add on. Recently I contacted VM and changed to the £10 for 10gb plan. Today my plan changed over and it’s showing that I’ve got 11gb data so I had a look on my portal and it shows that the extra 1gb came from the ‘Data Rollover 1gb’ add on (from my previous plan). I’m just wondering if this will affect my 10gb rollover? As my base data is 10gb, I got the impression that if I use 2gb this month then next month I will have 18gb to use?
