Data bolt on has disappeared

[Chloex]

Hi, I recently got my O2 contract about 3 weeks ago I was told I’d have 30GB data.. later I found out this was 15GB tarrif and 15GB bolt on I don’t know the difference so didn’t think nothing of it it came up as an overal 30GB so I assumed it was fine. I got a pac code from EE (my old contract) to transfer my old number onto this O2 SIM card and ever since my number transferred over my data bolt on has gone and I’m left with just 15GB which I am nearly out of and I still have 10 days left. Does anyone have any idea why my bolt on is gone?

Ahh I see thank you! So when this 15GB ends it should start again as another 15GB that’s what confused me

Yes, that;s correct @Chloex

Okay thanks I was only confused because before it was showing up as a total of 30

It was wrong to show 30gb before. It should have always been 2 x 15gb.
