25GB data

25GB of data: How much is it and how long does it last?

If you’re looking for a data plan that can last you the whole month, 25GB data SIM could be exactly what you need. In this guide, find out how big 25GB is, how long it can last, and if it’s the right amount of data for you.

How much is 25GB of data?

25GB is equal to 25,000MB. 

Compared to other data plans, 25GB is quite a lot. According to Ofcom, the average person in the UK opts for 4.5GB each month. That means 25GB is 5x greater than average! 

Saying that, it all depends on the type of user you are. If you’ve tried a 10GB bundle before but found yourself running out of data, why not upgrade to a 25GB data SIM?


How long does 25GB of data last?

Mobile data is measured in megabytes (MB) or gigabytes (GB).

To find out how long 25GB can last each month, let’s take a look at how much common activities consumes on average:


Data consumption

Browsing the internet

60MB per hour

Listening to music


10.8MB per hour (24kbps)

43.2MB per hour (96kbps)

72MB per hour (160kbps)

144MB per hour (320kbps)

Watching Netflix

1GB per hour (standard definition)

3GB per hour (HD)

Watching YouTube videos

1.56GB per hour (1080p)

2.7GB per hour (4K)

Browsing social media

90MB per hour (scrolling)

156MB per hour (interacting)

Using Skype / FaceTime


270MB per hour


180MB per hour

The more data hungry the activity, the more you will use up every hour. For example, streaming video content is data-heavy, as video files tend to be rather large. Compare this to say, opening a web browser or streaming music, which have much smaller file sizes. 

Reduce your data usage

Top tip - minimise your data usage by downloading content ahead of time (when still on Wi-Fi). You won’t need to use up any mobile data to play them. 

You could stream using a lower quality, although you might not need to worry about this with a 25GB plan! 


How many hours does a 25GB data SIM last for?

With the information above, we can now calculate how long you can spend on each activity with 25GB of data a month.

Browsing social media

160 hours (interacting)

Using Skype / FaceTime


92 hours


138 hours

*Calculated based on data consumption values in previous table - 25000MB or 25GB / XXMB or XXGB


With 25GB of data, you could stream audio for a very long time each month, though it’s unlikely you’d find time to listen to 578 hours of music! 

Needless to say, you would have more than enough data to browse the internet and social media.

You’d also have plenty of room to watch videos too. 25 hours of Netflix is quite a lot really, especially when out and about. Maybe you’d want more if you have a long commute and watch a lot of videos each way. In that case, why not consider unlimited data

Overall, 25GB provides a good chunk of data suitable for most people and their needs.


Is 25GB of data enough for me?

A 25GB data bundle is enough for you, if you:

  • Like to stream music quite regularly throughout the month
  • Watch video content occasionally, like when commuting or travelling
  • Interact on social media quite regularly
  • Consistently use data to browse the internet
  • Video call friends or family a couple of times a week

If you only use your mobile data to browse the internet, we wouldn’t recommend a bundle of this size.

I love ASDA mobile for me it's great and I love having my phone on the ASDA mobile network also good bundles without any contract commitments


Never had any problems using data or phone calls. Great price for month to month contract. Purchased another Sim for my son as it’s half the price of our Virgin Media contract.


I have been with Asda mobile for some years now. I personally believe their service and value for money the best I've come across. I can honestly say that Asda mobile is the best out there.
