"Connection timed out" refers that the device has internet connection (it is possible to browse the internet) but MMT cannot establish connection with Telema server within given time. At the same time everything is working in wifi. Thus the problem is in data connection settings.
Check the data connection settings:
Press Menu button of the device > go to Settings > Wireless & Networks (or similar) > Mobile networks > Access Point Names (or similar) > "EMT Internet" must be selected. Change if necessary, quit settings, and try update data or send documents in MMT again.
