Everything worked just fine for about 1 month when all of a sudden, my mobile began to display at all times: "Insert SIM Card ". Only the mobile they me supplied walking even worse than the other ( some buttons do not work) , then a second exchange where I still got a mobile that does not work and a third took place. Please help.

Your phone has no contact with your SIM card. We recommend :

* Clean the connectors on the SIM card using a soft brush , cloth or cotton swab moistened with alcohol colorless and fragrance free.
* Check that the card is damaged or worn.

If your SIM card is damaged or not working properly after cleaning , contact your operator to get a new SIM card .

Your phone is probably locked to a SIM card of a specific operator . This usually happens when you buy a phone from an operator . Phones whose SIM card is locked can be unlocked - please contact your operator for more information.

I think it stems from the SIM card , try then it in another phone, in the like example. Then if your phone displays the same error goes to your operator and will require a SIM card change . But if it comes from the V600 , it must be under warranty for t'aille the SAV repair. In the Settings menu -> Connectivity - > menu of connectivity Network . You select the GSM mode.
