Recently got a reconditioned and guaranteed tipo dual. It fails to register a network with the message 'your card does not allow connection to this network'. I have tested both SIMs in other phones and they registered immediately. The phone also has problems reading an SD card. It has no problerms connecting to my network however. Reading other posts here, I gather that this phone has not been entirely fault-free. Nonetheless I'd appreciate views on whether the problems can be cured as, in theory, the phone meets my needs perfectly.
