Mobile Operator O2 UK Boosts Data on Pay As You Go Plans

Mobile network operator O2 (VMO2) has today refreshed some of their SIM Only “Pay As You Go” mobile plans (Big Bundles), which sees a number of their plans getting a data allowance (mobile broadband) boost for no extra cost. The £15 for 25GB “Rolling Plan” has also been boosted to 30GB, although the rest of their Rolling Plans are unchanged.

Big Bundles and Rolling are both PAYG style SIM only plans that give you an allowance for call minutes, texts, and data. With a Big Bundle, you top up each month, and O2 exchanges the credit for your chosen Big Bundle. With a Rolling plan, you set up paying for your monthly allowance using your debit or credit card (i.e monthly payments will be taken automatically, and your allowance will refresh).

NOTE: Big Bundles also support data rollover (you can roll over up to 100% of your monthly data allowance into the next month), but only if you keep it topped-up each month.

As usual all of their Big Bundles include unlimited minutes and texts, thus the main change this year is in their data allowances. For example, their £10 plan now includes 8GB of data (up from 7GB), while £15 gets you 25GB (up from 20GB), £20 includes 40GB (up from 30GB) and their top £30 bundle gives you 125GB (up from 100GB).

All of their Big Bundles include free EU roaming, while plans from £15 upwards also include 50 international minutes to 42 countries.

    Is 02 pay as you go still only 2/3/4G based no 5G in sight ?

      3G is being turned off in more and more places, so your PAYG is only good for data in such places, as O2 PAYG gets no 5G, no 4G Calling… USA, Germany, Italy, Greece – all off the menu now for O2’s PAYG customers!

    And still no Wifi calling or VoLTE on O2 PAYG or any of their MVNOs.

      Im on Sky mobile (contract), which uses the O2 network and have WiFi calling and VoLTE.

      Virgin Mobile had VoLTE/VoWiFi, same as Tesco and like someone else pointed out, Sky.

      I’m on Sky Mobile too, VoLTE but no wifi calling, presumably because the firmware has it locked down. The chip supports wifi calling, as does wifi 6 but alas. locked to wifi 4 and such.

    lowest one is a tenner for 10GB, ok if you want to use 10GB maybe, but Smarty gives you 40GB for that, also they have a 5GB one for £6, for people like myself who don’t use a load of data and don’t want to pay too high a price. 5G as well if that is what you want, and Wi-fi calling.
    Not sure about Esim, but since most phones as far as I know can use normal SIM that is not loss. The only thing I am worried about is Vodafone grabbing hold of Three.
    If that happens, we will be left with just three networks and not impressed with any of the ones that will be left to be honest

      Lebara also offer much better value than this too, through uswitch or MSE you can get 5gb for £4.90 (1st 6 months £1.99) or 12gb for £6.90 (first 6 months £1.99), 21gb for £7.95 or 30gb for £8.95 I believe. Use Vodafone network

      @Mark. thanks but I am ok where I am, three is a reliable Network, as reliable as 4G is in this country.

    it is boosting the speeds to something usable, no point in giving you data if the experience is from 2003

      I am in the outskirts of Edinburgh and on 02 pay monthly now due to being one of the cheapest wasn’t expecting stellar speeds but currently running at 210mpbs indoor as well on 4G in a small town on 02 and was only getting 90mpbs from EE on 4G must just be certain areas where 02 are dire.

      Yeah @Declan – I typically have full bars on 4G, granted limited to a max of 150 down and 50 up but most I’ve seen is upwards of 60 indoors download. It’s actually worse outdoors with it only hitting around 18-33 although it did more level around to 35.77 and such more often than not indoors. I tried with the O2 SIM I have too – same thing given sky uses O2’s network.
