When the message sim card registration failed comes up it is usually as a result of one of 2 things the first being that the phone has not recognized the sim card due to an improper fixing or the sim card has become faulty. Simply try the sim on a different mobile device to determine if the sim card is still good.

The SIM registration failed because Nokia C7 is not a CDMA phone. It is GSM phone.
Also, WCDMA is different from CDMA. In simple terms, WCDMA is a 3G technology for GSM connections just like EVDO in a 3G technology for CDMA phones.
So you have to buy a GSM connection.

Factory resetting the phone will do absolutely nothing with this problem

There are 3 causes of Sim Card Registration Failed, when you first turn on the phone, the sim card attempts to connect to the network if it can not do this it gives a message like Sim Card Registration failed.

1, The sim card is turned off (is it Orange) if you have had the sim card for a while and it hasnt been used they will turn it off, you need to contact them from another phone to get it turned on or get a new sim card.

2, The phone has a hardware reception problem, when it attempts to register itself with the network it can not... There is a reception problem and it requires repairs, this isnt really an easy diy job on this handset.

3, The phone is blocked, i.e reported lost or stolen. Some networks when a phone is reported will allow it to get reception but will not let it make calls, however other networks will not give it reception at all and hence you get a Sim Card Registration failed message.

I hope this helps, these are the causes of the message.
