At first I was thrilled with the phone. Then I could not explain why I was sometimes not accessible to me. Again and again was on the phone -> Emergency call only. Now the test began, very tedious. The second SIM slot works, but not 3G, but only with EDGE. The first SIM slot has always failures, at first I thought it would be the SIM card in the SIM frame - gained> new SIM. But even then, did not work the first SIM slot. Again and again had to read -> Emergency call only -> thus no reception. If, now back on Airplane Mode, and again, then he finds the net. But after 1 hour again the same -> Emergency call only. So I can not recommend the phone. I can exchange it no longer because the deadline has expired. My tests have lasted too long. :-(
