I am looking at my phone's configuration and i am not sure about the passwords because they are shown as asterisks, but anyway here you go:
For Internet:
- access point: internet
- username: internet
- password: try 'wap' or 'internet'

For mms:
- access point: mms
- username: mms
- password: try 'mms'

For wap:
- access point: wap
-username: wap
-password: 'wap' i guess


if you have any doubts try calling 107 or +973 - 36107107.
