I received a text notification from someone in my contacts saying that a EE photo message was sent to me, but couldn't be delivered. It said that a message will follow on how to view it and it gave a password. As it was from someone in my contacts, I stupidly clicked on the link (eeuk.mms.ee.co.uk) and entered my mobile number and the password. It came up with just a brief text message. The person in my contacts said they hadn't sent me anything when I asked, so now I'm really worried about malware.
That's a genuine message from EE. It seems you need to update your settings so you can receive MMS (Multi Messaging Service). For most phones, you can download the MMS settings needed from the online setup tool, so you can receive MMS directly without being falsely directed to EE's download website.
