Let's get into why you asked. For example, CDMA is pretty much an USA thing. I found coverage to be spotty compared to ATT, Tmobile and others and being locked to the provider's phones a real pain.
Just on the lock alone I ignore CDMA and use GSM phones now. My service is from Ting.com.
How different is GSM to CDMA? Both works for telecom service providing, so what are basic differences?
Which is better to adopt?
