By default, international roaming is switched on.

UK costs

Calls and texts

The standard voice tariff costs £2 per month. This includes all local, national and UK mobile calls as well as domestic text messages.

Calls to 0844, 0845 and 0870 numbers and other premium rate services are chargeable.


The voicemail service is provided as standard and free of charge on College mobiles.


We have a shared 1TB of data for all College mobile users so individual data limits are uncapped. This doesn’t mean data is unlimited as individual usage will be monitored and non-work activity will be blocked.

Also included in the smartphone data tariff is 50 MMS messages per month.

International costs

Data roaming – Europe

All College mobile devices have O2’s “Roam Like at Home” service activated as standard which includes:

Making calls and sending texts within the Europe Zone to any other country in the Europe Zone (including the UK).

Receiving calls and texts in the Europe Zone.

Using your monthly data allowance whilst in the Europe Zone.

What’s not included?

Making calls or sending texts from the UK, to countries outside of the UK.

Making calls or sending texts to premium rate numbers, directory service numbers and some non-geographic numbers (which can vary over time). Find out more

Mobile broadband tariffs, as they can only be used in the UK.

For more information and to see a list of countries that are part of the Europe Zone please visit the O2 website.

Data roaming – outside of Europe

By default, all users have O2’s Rest of the World 24-Hour Pass applied to their connection which costs £4.95 per day (ex. VAT) and provides up to 500MB of data per day depending on the country you are visiting.

Also included is up to 300 minutes of calls and 300 text messages per day.

Please check the specific allowances for the country you are visiting prior to travel on the O2 website 

Usage limits

All staff mobile devices have a lower and an upper usage limit. This is a requirement of our auditors and helps mitigate costs in the event of a mobile being lost or stolen.

When you reach your lower limit you will receive a text message advising that your usage is unusually high and you may find your service restricted. When you reach your upper limit your service will be barred and you will no longer be able to make calls, send text messages or use mobile data services (you will still be able to use WiFi).

By default the lower limit is set to £200 per month and the upper limit to £300 per month. These limits can be increased if your Telecoms Representative submits a request to the ICT Service Desk.
