Hi guys how can I find out, if my D620 has got a UMTS/HSDAP modem integrated ? There is a slot for a mobile sim card under the battery. When I put my Vodafone UMTS Simcard in, nothing happenes. It would be cool if I wouldn´t need a USB modem Stick like most others need. Please help ! How can I activate it ? What drivers do I need for windows 7 32bit ?
