I am traveling a lot and I need to be online on my laptop. How can I use 3G connection of my phone to browse internet on my PC?
I have Samsung Omnia 7.
Internet sharing or "Tethering" is an option that is not available on all Windows Phone devices. it is a feature that can be build by one of the OEM's
HTC provides tethering on their devices and it can be found in the settings menu.
There are rumours on Nokia working on an update to provide it on their Windows Phone devices as well.
I'm not to sure about Samsung providing this but found this workaround on the internet explaining how to get tethering working on a samsung device (only through usb cable not wifi)
the workaround for Samsung devices: (not supported by Microsoft or Samsung and untested by me)
I haven't tested this workaround since i don't own a Samsung device. i just found the instructions here
For the Dell Venue Pro there are steps and drivers to enable USB tethering is this thread. Wifi tethering is not possible on the DVP.
Whilst the phone is in USB tethering mode it cannot sync with Zune until the untether process is carried out, all other phone functions are unaffected.
This does not require the phone to be unlocked or rooted, and the process can easily be reversed.
The steps for Windows 7 are:
If you want to untether, follow steps 3-10 and click on Zune to switch your phone back into normal sync mode
Note, for me I didn't need to perform steps 13 and 14 for it to work, but you may need to depending on your network.
However, if you really need the feature (and likely stuck in some sort of contract) it is possible to flash this particular phone with a firmware from an Australian provider (use at your own risk).
