Nokia c7 sim card removal i don't now how ??


Insert the SIM card and battery

Important: Do not use a micro-SIM or a micro-SIM with an adapter in this device. This device does not support use of micro-SIM cards, and use of incompatible SIM cards may damage the card or the device, and may corrupt data stored on the card.

Follow the instructions carefully, to avoid damaging the back cover.

Safe removal. Always switch the device off and disconnect the charger before removing the battery.

1 Unlock the back cover release latch, and lift the back cover

2 If the battery is inserted, lift the battery out.

3 Insert a SIM card. Use the diagram printed on the device to correctly align the card.

4 Line up the contacts of the battery and the battery compartment, and insert the battery.

5 To replace the back cover, direct the top locking catches toward their slots, and press down until the cover locks into place.

In case of a problem or clarification or my solution was insufficient, don't hesitate to post me a reply.

If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

My nokia c7 phone shows sim card registration failed whenever i insert a CDMA sim. The manual says it supports WCDMA. Please help


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.

You can try to remove your sim, insert it again and try restarting the phone. Usually this problem is due to sim card not being place properly.

If the phone freezes
