Disadvantages to CDMA are

Your handset can only be used with the provider that you got the phone from. Should your phone brake under contract but out of warranty, getting a new phone from the provider will automatically extend your contract another 2 years.

CDMA is limited to North America and a few other places, GSM is worldwide. If you like to travel oversea's, for the most part, leave your CDMA phone at home.

GSM phones can be unlocked meaning that they can be used with any GSM provider. If my GSM phone brakes, I can get a cheap replacement phone without having to extend my contract. When I travel oversea's, I can continue using my service, better yet, I can use a local sim card for the country I am in and make and receive calls at a much lower rate.

Disadvantages of CDMA include:

1. Due to its proprietary nature, all of CDMA's flaws are not known to the engineering community.

2. CDMA is relatively new, and the network is not as mature as GSM.

3. CDMA cannot offer international roaming, a large GSM advantage.

4. As the number of users increases, the overall quality of service decreases.

There is no such thing as a CDMA card so there is no card for a CDMA device to accept. With a CDMA device you have to contact the service provider and give them the new device's ESN and once they have that changed in their system they will walk you through manually programming your new device.
