6680 works in offline mode! - GSM-Forum

Harisk · 11-01-2007, 07:54

6680 works fine with some SIM but don't accept some other SIMs, it works in offline mode. All SIMs I checked is GSM 900 MHz. All the SIMs are working fine in other handsets. What is the problem? I heard SIMs come in two voltages viz. 3v and 5v or so. Is it the problem with voltage difference? HELP!
