One of the major drawbacks of the WP7 OS from Microsoft is that it does not support USB tethering. However, if you own a Samsung based WP7 device – Focus or Omnia 7 – then you can enable USB tethering. The folks over at HDBlog.it have managed to enable USB tethering on the Samsung based WP7 devices by just entering a simple code. Users need to dial ##634# to enter diagnostic mode on their phone.
After that, users need to select Modem, Tethered Call’ option, approve a few prompts and they are done. The folks over at Mobility Digest have even written a step by step tutorial on how to enable USB tethering on your Samsung WP7 based handset. Sadly, the same method does not work on any other WP7 handset from any other manufacturer.
Hopefully, someone will find the way of enabling USB tethering on other WP7 based handsets. Until then, we can only wonder why Samsung and Microsoft did not enable tethering by default on the Omnia 7 and the Focus.
