Start -> Settings -> Connections -> Work -> Modify
Modem -> New ->
Type Name for Connection
Select Modem -> Cellular Line (GPRS)
Baud Rate -> Any or Maximum
Tap Next
Enter Access point (mnet or waselmnet)
Tap Finish
When connection is made, a pop up box appears asking for username and password. Enter username mnet password mnet (or waselmnet/waselmnet if applicable), make sure that you have entered correct username and password, tick save password and tap OK
In case password and/or username is incorrect, there is only one way (as far as I know) to correct it, and that is to delete the modem connection and create new again.
Settings were taken from Etisalat mnet website as well as help received from Emirates Computers Help Centre.
