Data usage and calling

In order to keep a grip on the costs for data usage, various user profiles were implemented on January 1st, 2019. Restrictions on data usage are included in these profiles. How these profiles are structured can be found below.

The following user profiles have been activated, as of January 1st, 2019:

Profile Data usage per month
within the EU-zone
Data usage per month
outside the EU-zone
A 2 GB Blocked
B 5 GB Blocked
C 10 GB Blocked
D Unlimited Blocked
E 2 GB 250 MB
F 5 GB 500 MB
G 10 GB 1 GB
H Unlimited Unlimited

How will this affect you?

Each faculty and service unit has allocated profiles to its employees; these profiles will be activated on 1 January 2019. Employees who have been assigned profile A will notice a change in that, from the date the profile goes into effect, they will have less data available to them (2 Gb instead of the current 5 Gb).

If you have a profile which allows you to use data in zones 2, 3 and 4, your data usage will be charged at cost price. Below you can read more about the costs for data usage in these zones.

Data amount Zone 2 Zone 3 Zone 4
1 GB (1.000 MB) € 302,50 € 605,- € 9.075,-

All employees will be able to place calls to or from any country in the world, without restrictions. Below you can read more about the costs for calling to or from countries in zones 2, 3 and 4:

As of 1 January 2019, it is no longer possible to purchase MB top-ups or Travel & Surf vouchers via the T-Mobile app. These were a temporary measure intended to keep costs in check. To use data outside the EU Zone (Zone 1), employees must have the appropriate profile.

No matter your profile, you will receive an SMS from T-Mobile when you have used up 80% of the data allocated to you in your profile. You will also be sent an SMS when you have used 100% of your data for the month, at which point you will no longer have Internet access (3G/4G). If you have a data-only SIM card you will not receive an SMS.

If you have any questions about the profile allocated to you, or if that profile is insufficient for the purposes of your work, please contact your ICT contact person. If necessary, they can submit a request to adjust your profile using ICTS Selfservice.

Using your mobile to access the internet means using data. Your usage will be measured in MB, not the amount of time that you spend online.

If you are connected to a Wi-Fi network (e.g. eduroam), you will not be using data on T-Mobile's network.

Examples of data usage and how many MB they use are as follows.

  • sending an email without attachments: 0.15 MB per message;
  • sending WhatsApp messages: 0.01 MB per message;
  • uploading a photo to Facebook: 1 MB per photo;
  • downloading an app: 5 MB per app;
  • streaming music on Deezer: 1 MB per minute;
  • streaming YouTube videos: 2.5 MB per minute;
  • streaming HD-quality YouTube videos: 11 MB per minute;
  • watching live TV broadcasts: 10 MB per minute.

There are various ways in which you can stay in control of mobile data usage:

  • use a data monitoring app. The app will track how much data your phone is using. However, you must bear in mind that the usage shown in the app will never be completely accurate or up to date. The information will always be indicative;
  • most devices will also have a built-in option in the settings menu that can track your data usage. Please visit T-Mobile Toestelhulp for detailed assistance specific to your phone;
  • use a Wi-Fi network whenever you can. The Eduroam Wi-Fi network is available at most educational and research institutions. You can log in to it using your AUAS-ID and password. This process will allow you to surf safely, without using any data included in your T-Mobile internet allowance;
  • always update your device to the latest software version. Tip: download updates when you are connected to a Wi-Fi network;
  • always close internet pages that you have visited;
  • turn off automatic functionality. Examples include app updates, notification services (e.g. Facebook), downloading of photos (e.g. in WhatsApp), apps that run in the background and HD videos.
