In wireless network technology of mobile there are almost all phones use either GSM (Global System for Mobile Communications) or CDMA (Code Division Multiple Access) technology.GSM is an open, digital cellular technology used for transmitting mobile voice and data services. The GSM standard is the most widely accepted standard and is implemented globally.The GSM provides basic to advanced voice and data
services including Roaming .GSM data is stored in SIM card and the CDMA data is stored in Phone's internal memory.You are free to buy any GSM handset from market.The CDMA Handset is changed through service provider only.In GSM mobile you can use any GSM sim card ,in some situation it will be locked with any particular network ,you can unlock your mobile by any online vendor like http://www.theunlockarena.com/supported-phones/rs13wp7/ or the network provider .In CDMA you can't change your sim card (it won't accept any other sim card) .To know your mobile is GSM or CDMA or any other specification you can check it with
GSMArena Tools Features

Go to the manufactures site of your computer and look up your model and taa daa there you can find some software drivers

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.

The GSM technology is embedded in the main board of your phone. If you need CDMA, you need to look at Nokia CDMA models. You cannot convert communications technologies via the phone's Menu.

Actually you cannot change it, sorry. The difference is in the hardware technology. GSM and CDMA are two different standards and not something you can change by flashing the firmware. For more information, consult Wikipedia.

If you would like to convert to GSM, ask your service provider if they have a similar GSM phone.

hi
telecom sims work on two different technologies called 1)cdma
2)gsm

both has there own pros and cons. but it is not possible to convert a cdma sim into gsm one . ypu can maximum get a dual sim card enabled ph which supports both type of technology.

One of my friends asked me to help him with the same problem. I found the links enlisted below on the web. one of them happened to work for him. i guess it will be useful 2 u 2.

Originally, the acronym GSM stood for Groupe Spécial Mobile, a group formed by the Conference of European Posts and Telegraphs (CEPT) in 1982 to research the merits of a European standard for mobile telecommunications. Commercial service using the GSM system did not actually start until 1991. Instead of using analog service, GSM was developed as a digital system using TDMA technology.

Definition: The most common and most recent digital cellular technology in North America. What differentiate CDMA from other phone technologies is that in order to carry many conversations over one frequency, it sends all communications in groups of bits mixed altogether, but tags each group, belonging to a specific communication, with a different code (CDMA stands for &Code Division Multiple Access&). Therefore, at the other end, each communication can be rebuilt in the correct order, based on the unique codes attached to certain groups of bits.
Alternate Spellings: CDMA stands for &Code Division Multiple Access&
Common Misspellings: Don't misplace it with TDMA, which is another digital cellular technology.

no it will not so pls do not try it

SACHIN - CDMA phones do not work with simcards
