I can repeat same thing with 6121c. I just do not need to cup the phone so much but keep it naturally. 3 celltowers visible and under range 1km here and in 10 seconds keeping phone it drops from UMTS to GSM network. Calls gets dropped or voice quality gets very bad that you can not make sure what other is speaking. Fix is to keep phone by four fingers nicely.
