I have no clue when or why the Bayanat (WiMax ISP division of Mobily) blocked Googe Earth. If you follow the instructions of the trouble shooting process it will not give you any indicator it’s blocked. However the software will never work successfully with you unless you connect to another provider.
The moment the connection is established, you may continue the browsing again through Mobily link. Funny thing, they just blocked the authentication part.
