O2’s Big Bundles Reviewed: Pay As You Go Packages from £10/month

October 11th, 2016

O2 offers Big Bundle packages from £10/month on Pay As You Go. The bundles come with an allowance of 4G internet, minutes and texts.

O2 Big BundlesIf you’re a customer on O2 Pay As You Go, you can buy a ‘Big Bundle’ package. This will convert your Pay As You Go credit into a one-month allowance of calls, texts and mobile internet.

The Big Bundle packages start from £10/month. For a £10 top-up, you’ll get a one-month allowance of 250 minutes, 1000 texts and 500MB of 4G internet. On higher-priced bundles from £15/month, there are more minutes, texts and mobile internet included.

In this article, we review the O2 Big Bundles tariff. We’ll start by looking at the full range of bundles available. We’ll then compare the Big Bundles to key alternatives available from other mobile networks (e.g. to giffgaff goodybags). We’ll then look at the coverage on O2 and at how you can keep an existing phone number when moving to Big Bundles.

Bundles & Pricing

O2 Cat - SIM Card

Customers who order an O2 Pay As You Go SIM card are normally placed on Big Bundles by default.

O2 is one of the UK’s largest Pay As You Go mobile networks. The company currently has a choice of three Pay As You Go tariffs:

  • Big Bundles: This is the default tariff for new customers on O2 Pay As You Go. Your top-up will be converted automatically into a one-month allowance of calls, texts and mobile internet.
  • Classic Pay As You Go: This is O2’s classic Pay As You Go service. You’ll pay on a per-minute and per-text basis, and your credit won’t expire providing your SIM card remains active.
  • International: This is O2’s specialist SIM card for international calling. It allows you to call abroad from 1p/minute.

By default, new customers will be enrolled automatically on the Big Bundles tariff. This is the best value option if you’re a regular mobile user or if you using a smartphone.

For light users who don’t have a smartphone, it may be cheaper to instead choose Classic Pay As You Go. This doesn’t have a minimum monthly top-up: you simply pay for what you actually use on a per-minute, per-text and per-megabyte basis.

Big Bundles

O2 Big Bundles 2016With O2’s Big Bundles tariff, you’ll automatically convert your Pay As You Go credit into a one-month allowance of calls, texts and internet. There are currently six Big Bundle packages you’re able to choose from:

NetworkMinutesTextsInternetMonthly
Cost
O21001001GB£10.00
O22501,000500MB£10.00
O27502,0002GB£15.00

O23,0004,0005GB£25.00
O23,0004,00020GB£30.00

The Big Bundle packages will last for one calendar month with any unused allowances expiring along with the bundle.

Upon the expiry of a bundle, O2 will try to renew the same bundle automatically (this is providing you have enough Pay As You Go credit remaining on your account). If you don’t have enough credit for auto-renewal, a Big Bundle will be added automatically when you next top-up your account.

Out of Bundle Charges

Top Up Logo

Out-of-bundle charges are 35p/minute, 14p/text and £1/day for up to 50MB of internet.

Customers who exceed the inclusive allowance on their Big Bundle package will pay 35p/minute and 14p/text for any further usage. If you run out of data, it’s an extra £1/day for 50MB of data (this will buy you O2’s Web Daily bolt-on).

The following table shows out-of-bundle rates on O2’s Big Bundles tariff:

Calling Rates:
Voice Calls 35p/minute (any network, any time)
Calls to Voicemail 30p/call (when outside of allowances)
Calls to Special Rate Numbers 55p/minute access charge
+ service charge from the company you’re calling
Messaging Rates:
Text Message (SMS) 14p
Picture Message (MMS) 35p
Internet Rates:
Mobile Internet £1/day (up to 50MB/day)

The prices in this table are stated for UK-to-UK only. If you’re travelling abroad or making an international phone call, higher charges will normally apply. Source for pricing information: O2 [1, 2].

Outgoing phone calls are charged on a per-minute basis (so the length of all phone calls will be rounded up to a full minute). For example, a 61-second phone call will be charged as 2 complete minutes (2 minutes x 35p/minute = 70p). There is also a minimum call charge equivalent to 1 minute (so you’ll pay a minimum of 35p per call).

Classic Pay As You Go

O2 Classic Pay As You Go

The rates on Classic Pay As You Go are 5p/minute, 5p/text and 5p/MB.

Customers who only use their phone on a very occasional basis will potentially be better off choosing Classic Pay As You Go.

On Classic Pay As You Go, there’s no need to convert your credit into a one-month allowance of calls, texts and internet. Instead, it operates on a traditional Pay As You Go basis: you top-up your phone and your credit remains until the time when you actually use it.

Customers on Classic Pay As You Go will pay a discounted rate of 5p/minute, 5p/text and 5p/MB. For more information on Classic Pay As You Go, please see the O2 website.

A Cheaper Alternative

For a better value alternative to O2’s Big Bundles, we recommend giffgaff and their goodybag offering. A low-cost sub-brand of O2, giffgaff uses the O2 network to provide their service.

Giffgaff Goodybag Icons - NewThe main benefit of choosing giffgaff rather than O2 is substantially lower prices and bigger allowances. For instance, giffgaff has a £7.50 goodybag with 250 minutes and 500MB of data. On O2, an equivalent Big Bundle will cost you £10/month.

The main downside of choosing giffgaff rather than O2 is you won’t receive an O2-branded service. You won’t be able to call O2 for support (instead, you’ll need to use giffgaff’s online-only support). You also won’t have access to O2 customer exclusives such as the Priority Moments app.

giffgaff currently offers a choice of seven goodybag bundles:

TariffMinutesTextsInternetMonthly

£5 Goodybag150500100MB£5.00
£7.50 Goodybag250Unlimited750MB£7.50

£15 Goodybag1,000Unlimited5GB£15.00
£18 Goodybag2,000Unlimited6GB£18.00
£20 GoodybagUnlimitedUnlimitedAlways-On£20.00

For customers without a goodybag bundle, giffgaff currently charges 15p/minute, 5p/text and 5p/MB. giffgaff also uses per-second billing with a minimum charge of 15p per call. Compared to customers on O2, members of giffgaff should find their calling allowance going a whole lot further.

For more information, please see our full review of giffgaff. Alternatively, you can order a free SIM card from giffgaff.

Comparison to Alternatives

In the following section, we’ll compare O2’s Big Bundles to rival offerings from other mobile networks.

£5 per month bundles

5 Pound NoteOn O2, the cheapest Big Bundle package currently starts from £10/month. A £10 top-up will give you 250 minutes, 1000 texts and 500MB of internet. In contrast, rival mobile networks can offer you similar for less money.

If you’re happy to have coverage from EE rather than O2, we’d recommend ordering a free SIM card from ASDA Mobile. For just £7/month, you’ll get 300 minutes, 2000 texts and 500MB of internet. This will save you £3/month compared to the O2 Big Bundle and will also give you a larger allowance of calls. You can check the coverage on ASDA Mobile in your area.

giffgaff250Unlimited750MB£7.50

£10 per month bundles

10 Pound Note

At the £10/month price point, O2 is offering a choice of two Big Bundles:

  • 250 minutes, 1000 texts and 500MB of internet (more minutes and texts)
  • or 100 minutes, 100 texts and 1GB of internet (more data)

You should choose your preferred Big Bundle based on whether the minutes & texts are more useful, or if you’d rather have additional data.

A better value deal compared to both of the options from O2 is ASDA Mobile’s £10 bundle. For £10/month, you’ll get 600 minutes, unlimited texts and 1.5GB of internet. ASDA Mobile makes use of coverage from EE.

Alternatively, if you’d like to have coverage from O2, it’s worth trying out giffgaff’s £10 goodybag. You’ll get the exact same coverage as customers on O2 but with much larger allowances to use every month (500 minutes, unlimited texts and 1GB of 4G internet).

Coverage

2G, 3G and 4G Coverage

O2 Coverage Map 2016

O2 offers 99% population coverage in the UK.

O2 has 99% population coverage across the UK. This includes 98% coverage on 3G and 78% coverage on 4G. On the Big Bundles tariff, customers will have access to all types of coverage including 4G.

Before signing up to the Big Bundles tariff, we strongly recommended checking the O2 coverage in your area. You can do this by entering your postcode on O2’s online coverage map:

Check O2 Coverage (o2.co.uk) »

We’d typically recommend O2 only if you’re able to get at least 3G or 4G coverage.

Before signing up to the O2 network, it may also be worth checking your coverage on ASDA Mobile (a cheaper alternative using the EE network). Alternatively, if you’re only able to receive coverage from O2, a SIM card from giffgaff may offer you better value than O2.

Tethering

Tethering or personal hotspot refers to the process of sharing your smartphone’s internet connection with other devices (e.g. with your laptop or tablet).

It’s now possible to tether on any of O2’s Big Bundles tariffs. If you’re using an iPhone, you’ll need to have iOS 10.1 or newer, with at least version 26.1 of the O2 carrier settings.  For more information, please see our in-depth article about tethering on UK networks.

Joining Big Bundles

Keeping Your Phone Number

Transfer Phone Number to O2 Big Bundles

It takes around one working day to transfer your phone number over to O2 Pay As You Go.

If you’re switching from another network to O2 Pay As You Go, it’s a straightforward process to keep your existing phone number.

To do so, you’ll need to ask your current mobile network to give you with a PAC Code. By law, they need to give this to you free of charge within two hours of your request.

Once you have that, order your new Pay As You Go handset or SIM card from O2’s website. When your new phone or SIM arrives, you can provide your PAC Code to O2 through this online form. After you’ve done this, your phone number transfer will normally take place on the next working day.

For a step-by-step guide on moving your phone number to O2, please select your current mobile network from the drop down menu below:

    Hi my brother is with o2 pay as you go he puts £10 a month on his phone but runs out of minutes how much more does he need to put on so he gets enough minutes to last the month

    1. Ken replied:

      Hi Diane,
      Thanks for your comment. See the table here for a list of O2’s current Big Bundles. For instance, if your brother were to upgrade to the £15 Big Bundle, he would have 750 minutes per month which should hopefully be more suitable!

    I know most of the comments are about tariffs, but I’ve a question about unlocking phones, can only the place I’ve purchased the phone unlock it, I’m waiting for a delivery of a new phone from O2 I’ve not signed up to a tariff with them but they are sending a £10 Big Bundle triple sim but I want to used another network, but after looking on-line it’s looks like I’ve got to be with O2 12 months before I can request to be unlocked, the phone is a OnePlus 3T and is a Christmas present for my son.

    1. Ken replied:

      Hi Helen,
      There’s more information here about unlocking your smartphone but in short: yes, the only “legitimate” way of unlocking your handset is directly from your mobile network (i.e. O2). Saying that, there are a couple of people on the OnePlus forum suggesting the handset might be provided unlocked (so possibly worth double-checking with O2 to see whether the handset is locked).

    How come 02 are way behind others? Us loyal customers don’t get any good deals like Giffgaff and ASDA. You are 100 times bigger company than those yet when you phone up and you manage to talk to someone there attitude is ‘well go with them then’.
    Sort something out for your customers who have been with you a long time like myself. As for the gurus you have in store in, they are useless arrogant and most times too busy talking c**p
