What You Get For Your Mobile Data

Mobile data can be a bit intimidating, especially at first as you get to grips with terms like gigabytes and download speed. At Tesco Mobile, we’re all about making thing less complicated and that includes breaking down the jargon when it comes to mobile data.

The biggest question people often have is what their mobile data limit is and, more importantly, what they can actually do with it.

Let’s take some simple figures to start with - a package like Tesco Mobile’s €30 plan gives you unlimited calls and texts and 15 gigabytes (GB) of mobile data every month.


This megabyte breakdown is important because it’s a small unit of measurement which is more likely to be used when talking about how much data is used for certain services.

Now let’s break this down further into looking at roughly how much mobile data some popular apps actually use.

Instant Messaging:   0.5 megabytes per message
Games:  0-2 megabytes a minute
Email with attachment:  1 megabyte per email
Web browsing:  1+ megabytes a minute
Facebook:  2 megabytes a minute
Music streaming:  2 megabytes a minute
Youtube/Netflix in HD:       6 megabytes a minute

These are estimated amounts as many variables make a difference - such as adding high-quality images to an instant message, browsing media-rich websites or playing games that have to be constantly connected to the internet. And do remember that uploading videos also eats into your mobile data allowance.

Data allowances

Your data allowance will vary according to the plan you have signed up to, or any additional add-ons to your package. 

If you are unsure of the data allowance available with your package, please check our plans page on the Shop tab. 

If you exceed your data allowance or have no data with your plan, you will be charged per MB for each data session with a minimum charge of 1MB.

Data charges

Tesco Mobile charges 3c per MB for any data used which exceeds your Billpay plan amount or 10c per MB when you go Out Of Bundle on Prepay. You can purchase bundles of data, and anything you use over this amount is also charged per MB. Each data session will be billed per MBClick here to see the available data add-ons.

There is an EU data roaming cap of €50 excluding vat. If you go over this amount while roaming, a bar will apply and you won’t be able to access more data. You can remove this by going online to My Tesco Mobile.

The cap renews automatically per calendar month for Prepay, and per billing cycle for Billpay. This means that the bar may apply even if you have previously removed the cap.

You can check how much data you have left by:

  • dialling *100*6# and pressing the call button
  • logging onto My Tesco Mobile
  • using our app for Android and iPhone

Data Troubleshooting

How fast should my data be?

The speed can vary based on a number of factors. The main consideration is the coverage in the area that you're using your data.  

I have 3G coverage in my area, but my data still isn't very fast?

We would recommend you check the settings on your phone to make sure you have the most up to date version. You can download these directly from our website here.

Is the speed of my data dependent on my phone?

Most phones are enabled for data, but some phones aren't enabled for high speeds. If you want to check if your handset is capable of high speed data, please check with the manufacturer.
