O2 UK Add Data Rollover as Standard to Pay Monthly Plus and Ultimate Plans

Mobile operator O2 (Virgin Media) has this morning announced that new and upgrading customers on their ‘Pay Monthly Plus’ or ‘Ultimate Plan’ (phone, tablet, or SIM only) can make the most of any unused 4G or 5G data (mobile broadband) each month as it will now roll over to their following months’ airtime allowance.

For example, if a customer on an eligible plan has a 50GB data allowance but only uses 30GB, the remaining 20GB will roll over – giving them 70GB to use at no extra cost the following month. If they then use 60GB of that data, no additional rollover applies, and their tariff will reset to the customer’s standard monthly allowance (in this case 50GB) for the next cycle.

Both the Plus Plans and Ultimate Plans from O2 offer other benefits and savings too, such as additional destinations to roam in (more than the standard 49 destinations), a 3-year mobile phone warranty and the ability to Switch Up, a perk that allows customers to switch their handset for any new phone of their choice, every 90 days.

Christian Hindennach, CCO of VMO2, said:

“We understand the need for flexibility – life is not always predictable – which is why we are always looking to evolve our plans and perks to meet life’s shifting needs. Data rollover is the latest benefit we are bringing to O2 customers to help keep them connected and entertained when they need it the most – at no extra cost.

Data rollover joins a host of other value enhancing benefits O2 customers can enjoy. From inclusive EU roaming, to 20% off airtime costs with Multisave, and a huge range of experiences and rewards on Priority, we’re committed to enriching life’s most important moments for our customers.”

Naturally this doesn’t benefit O2’s unlimited data plans and the double data Volt benefit is also excluded. Any data that does automatically get rolled over will last for 1 monthly billing cycle only.

    Why don’t O2 do wifi calling abroad?

    1. Avatar photo Name says:

      It took them months to stop exposing user location and the only reason why they’ve fixed it, was because it was publicly disclosed. They might be not aware that it is not working abroad.

      No other network does it either. One issue maybe that if you move outside your wifi range your phone would move to VoLTE and you could be charged without knowing it.

      @ACDeag But wifi calling doesn’t bypass roaming 😀 Except if you setup a wifi network routing via the vpn back to UK, but I haven’t tested this.

      T-Mobile USA has supported it from the day they launched VoWiFi. There’s zero reason to not enable it. It’s just a money grab.

      EE offers Wi-Fi calling when abroad but they recommend turning it off when abroad to avoid being charged for roaming, even if you have a plan with inclusive roaming.

    Took a long while to bring that over from VM, although from what I can tell, it doesn’t exactly work the same? VM had the rolling allowance first before then going onto your regular contract allowance.

    This should really be on all plans rather than those expensive ‘plus’ plans honestly.

      Why is this a selling point? Do people really build up their data and then all of a sudden go, “oooo, I might just use a load of data this month?”

    2. Avatar photo Spurple says:

      @TG, no. Instead people will take a cheaper plan with a lower data allowance, safer in the knowledge that there will be extra allowance available on the odd month where their usage is higher than normal, saving some change on a month to month basis.

      Sky Mobile have been offering this for ages, but it’s a pity that Sky only caters to iPhone users and a very select list of Android phones. I’m referring to features like Visual Voicemail and eSim.

      @TG, I remember years ago, before the days of smartphones, some networks used to have calls and text roll over. That was after the days when you had to pay for each text and call. 🙂

    4. Avatar photo insertfloppydiskhere says:

      @TG when I was on Virgin Mobile, the rollover allowance was really helpful when I was actually using data when being out at places given that I was on a 2GB plan at the time (it would be 4GB with rollover which is the max I’d ever use on VM). You’ve already paid for the data so why can’t you use it whenever you want?

  3. Avatar photo Jeff says:

    Bit late to the party on this. Sky who use O2 as the carrier have offered data rollover since launch and it saves for 12 months on a rolling basis. Just a gimmick I would say from O2.

  4. Avatar photo Rik says:

    Can anyone get a fast enough connection to use any data on o2 to avoid rolling any over? The signal and speeds are awful for me. Even on 5G SA, I get maybe 5 Mbps at the most.

    On a serious note, I know it depends on the area. Happy Friday.

    Great, but since they took on Virmin Medias customers network congestion has meant I haven’t been able to access the O2 network at home
