I know that this problem has been written all over the internet but seriously... no solution? The E71 works perfectly with other sim cards and no, it's not blacklisted. The sim card I want to use works perfectly on other cell phones like my Sony Ericsson (which I don't want to use). My E71 is not sim-locked and I do not know where to go than here! A weird thing is that the E71 can not find the operator I want to use either and the operator's net is really good on other phones. I really do not get this. Could any one please help, thanks!

If other SIM cards work normally, and you've tested multiple cards from your preferred operator, then there's something odd about their cards. The E71 was first released in June 2008. Is the Sony Ericsson phone considerably newer? That might give at least a half answer about why they act differently.
Not all SIM cards are created equal. For example, there are whole FAQ's describing the differences between Nextel SIM cards here in the USA: http://reviews.ebay.com/Nextel-32k-64k-and-128k-60
I hope that helps a little.
