If you need to use your mobile device abroad, please refer to our guide to Travelling abroad with mobile devices before you travel.

Users MUST notify IT Services as soon as is practically possible of any lost or stolen devices so appropriate actions can be taken to prevent any possible fraudulent activity or data security breaches. Please also advise IT Services of any transfer of devices between colleagues.

  • Connection to the mobile provider’s network, currently Vodafone
  • 4G data connection - see Vodafone UK-coverage-map

To request a new connection, new device, change or cancellation, or to report a lost, stolen or faulty mobile device please contact the IT Service Desk:

Personal Mobile Phones

Note: The University will not reimburse you for hiring, leasing or purchasing such equipment of your own.

Costs for occasional ‘work’ calls (but not line rental or equipment costs) made on personal mobile devices may be claimed back on expenses (these must be supported by an itemised bill, with the relevant calls highlighted); however, overuse of this facility will be deemed as a deliberate attempt to circumvent the above requirements. See the Mobile Telephones Section of the University Expenses and Benefits Policy.

Privately Owned Devices and MS Exchange

You can use privately owned iPhones, Androids, and Windows Mobiles to connect to Microsoft Exchange for Outlook email, calendaring and contacts. See our Wireless fact sheets for guidance on configuring your device.


Voicemail at the University is part of the Mitel telephone system. It is available on all University four-digit telephone extension numbers and we can make adjustments for shared telephone extensions and for anyone who has more than one telephone extension.

Note: Voicemail is not automatically enabled but is available on request via the IT Service Desk –, or

Setting up voicemail

After we have created your voice mailbox you will receive confirmation including a default passcode and instructions on how to personalise your mailbox.

You must follow the instructions in the Voicemail First time set up guide and complete ALL three set up steps otherwise callers will hear an anonymous generic greeting and may not be confident that they’ve reached you.

Voicemail user guides

  • Forwarding calls
    When your voice mailbox is created, callers are automatically diverted to voicemail by default, either when you’re on another call or if you don’t answer within six rings. However, you can switch diverts off and on by changing the divert options on your office phone.
  • Receiving and listening to messages
    When a caller leaves a message, you will receive an email notification with the voice message attached. If you share a phone, you may have a flashing lamp on your phone instead.
  • Access voicemail and passcode reset
    You can access your mailbox to listen to messages or reset your passcode from any phone.
  • Changing your greeting and name
    Change the greeting your callers will hear.
