We often get asked ‘Does O2 do a Unidays discount?’ Well, the excellent news is that there is a Unidays O2 code to get 20% off Airtime plans and also now off selected accessories too!

To get it, you need to head to the page, get the Unidays code and then follow the instructions. It’s easy to use the code and is well worth it for 20% off.

There are a couple of other discount schemes in the UK such as NUS Totum and Student Beans and below we now look into whether they offer a discount too. This information is correct as of February 2021.


There is no NUS Totum O2 scheme at the moment for students to save. This includes not being included in the NUS Extra card scheme.

HOWEVER, NUS students qualify to get the discount. Just head to the student page follow the instructions and you can get a 20% discount on O2 contracts.


Nope, there is no association between Student Beans and O2.

3. O2 PRIORITY OFFERS and Refresh Airtime

One big advantage of getting a mobile contract with it is you get access to O2 Priority.

O2 Priority is exclusive to customers and gives them special offers such as rails offers, a great device plan, priority ticket releases for gigs and events and high street vouchers. There are some great 02 online discounts there that could help you save money throughout your university career.

What is O2 Refresh Airtime?

Refresh Airtime is the name of the contract that O2 offers. The contract payment is split into two parts., the device plan and the airtime plan. The device plan is the cost of your phone or tablet and the airtime plan is the cost of your calls, data and text messages. This means that once you’ve paid off your device plan O2 automatically lower your bill. It also makes it one of the most flexible contracts out there as students can upgrade your phone at any time without having to make upfront payments.


So throughout the year, there are O2 promo codes that are regularly released to take advantage of to save money on their contracts and mobile phones – as well as sometimes broadband and tablets.

Frequently Asked Question

  1. I am a student looking for the best airtime plans around, offers on mobiles and general student airtime plans such as o2 refresh. They look a good option but I am also looking at Three and Vodafone, which do suggest?” Not a straight forward question, firstly we think that the 02 student discount is one of the best deals on the market today but you’ll need to personally think about how you are going to use it and look at a range of airtime plans. Do you need lots of free minutes? A new phone? Tablet? How much data do you need? Once you have that info you can effectively cross-check all of the airtime plans and see which is the best that may be o2 refresh as you say. The o2 refresh is one of the best ways to save.
  2. Are they the best phone contracts for students or should you use other offers like an o2 promo code?”Good question. Mainly you won’t beat the students discount as that is the best student offer. Student discounts, in general, are the most generous a company can give. It is a good idea though when seeing an 02 promo code and looking for a new contract, to see where you can combine an o2 promo code with students discount, to get more savings and the best airtime plans. It will depend on terms and conditions but worth a go.
  3. As well as discounts on phones and o2 airtime plans (including monthly bill options) can you get discount in tablets? As well as discounts on airtime plan they offer student discounts across products as well, so check online and in-store. Also check the refresh packages.
  4. Can you combine an o2 promo code, general sales offer and the students discount?” This is down to the retailer and their terms and conditions, sometime they will allow you to combine and double up offers. It’s always worth an ask. They are a great retailer and often generous so pop in-store or online and they will be helpful. Always see if you can work with o2 refresh scheme as well, to really maximise things.
