In response to the problems with Orange UK broadband and 3G broadband during March 2009 and April 2009 the 3G data network has been upgraded to 3.5G and increased signal coverage. This new network can be seen in action on many mobile phones which display network for instance the Nokia N95, when the phone detects the higher speed. The Orange UK mobile broadband USB adapter works with the new network. The 3G networks for all telecommunication suppliers still struggle to get the throughput that was originally advertised when these networks were announced. The UK Telecoms Regulator has reported on the challenges for all suppliers.
