25GB of Data: How Much Is It & How Long Does a 25GB data SIM last?

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:

Activity	Data consumption
Browsing the internet	60MB per hour
Listening to music	Spotify 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	Skype 270MB per hour FaceTime 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.

Activity	Time duration with 25GB*
Browsing the internet	416 hours
Listening to music	Spotify 2,314 hours (24kbps) 578 hours (96kbps) 347 hours (160kbps) 173 hours (320kbps)
Watching Netflix	25 hours (standard definition) 8 hours (HD)
Watching YouTube videos	16 hours (1080p) 9 hours (4K)
Browsing social media	277 hours (scrolling) 160 hours (interacting)
Using Skype / FaceTime	Skype 92 hours FaceTime 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.
