Unable to connect by 3.5G. I am using CSL data sim card (APN: hkcsl). I also tried 3 data sim card (APN: ipc.three.com.hk), and still cannot be connected. However, when I switched to a 3 sim card with data and voice (APN: mobile.three.com.hk), it works. Anyone has this problem and suggestion for solution. Thanks
